EV Pillars | Taking Charge of Safe & Reliable On-street EV Infrastructure

EV Pillars by Lucy Zodion

Background

With a key driver for the electrification of vehicles being the environmental benefits they promote, electric vehicles (EV) are becoming pivotal parts of urban regeneration.

Reducing emissions and improving the carbon footprint of both individuals and communities, EVs and their supporting infrastructure, such as EV Pillars, are now vital assets for cities and towns throughout the world.

There are a number of initiatives throughout the UK that are helping to drive the uptake of EV. One of these initiatives is the ‘Go Ultra Low City Scheme’ (GULCS) procurement framework, which has been set-up by London Councils, TfL and the GLA, to ensure the Capital’s transport network meets its aim to be the Ultra-Low Emission Vehicles (ULEV) capital of Europe.

The Scheme has four main streams of work which focus on making residential charging available, increasing the provision of rapid chargers and increasing the provision of charging infrastructure in car club bays. This increased uptake means solutions are required that not only make EV charge points more accessible, but ensure the supporting infrastructure is capable of providing a consistent, safe and reliable power supply.

ubitricity is a market leading supplier of on-street EV charging solutions, integrating them within existing street furniture to make on-street charging available and simple to use.

The EV charging specialist recently carried out work as part of the (GULCS) by transforming existing street lighting columns into on-street charge points, throughout London and surrounding boroughs. As the UK’s market leader in the provision of connection equipment for external lighting infrastructure, including the sole supply of street lighting cut-outs and isolators in to the UKPN electrical network, ubitricity selected Lucy Zodion as its solution partner for the project.

Challenge

The main challenge of the project was to support the transition of the use of the streetlight.

From being solely used to illuminate the street, it is now required to become a multipurpose piece of street furniture, providing both illumination and EV charging facilities simultaneously, while ensuring power and protection to both equipment and people, in-line with electrical regulations.

EV charge points fall into four main categories according to the charge speed – Slow, Fast, Rapid and Super.

Objectives

Lucy Zodion worked with ubitricity’s UK Operations Director to provide a certified and approved solution that works alongside existing street lighting infrastructure. The key objectives for the EV project included feeder pillar design to satisfy the following criteria:

• Reliable Power – The solution had to meet all relevant industry standards, as well as those outlining the safety of users. It also had to demonstrate a proven track record.
• Safe – As the lamppost is being transformed from street furniture to a point of public access, the solution needed to consider not only electrical safety within the street lighting column, but the safety of the end-user while accessing EV charging equipment.
• Readily Available – As the project was on a short-lead time, Lucy Zodion was required to provide a distribution pillar solution that was immediately available.
• Multi-purpose – The power distribution solution was required to provide appropriate protection of both the EV charging equipment and to protect the user from electric shock in line with industry standards. The solution had to provide a separate feed to the luminaire to ensure continual operation in the event of electrical issues.

Project Summary

• Project Name: Taking charge of safe and reliable on-street EV infrastructure using Lucy Zodion feeder pillars manufactured for EV sector
• Location: Greater London, UK
• Completed: 2019
• Pillar Installed: Lucy Zodion single phase secondary isolators

Collaborator: ubitricity

Solution

Lucy Zodion’s solution was to manufacture and supply several thousand secondary isolators to provide 32A supply protection and lockable isolation for the street lighting column. They provide 25A residual protection for the 5.8kW EV charging equipment,plus 6A protection for theluminaires. The product installed is:
• Product Specification: Lucy Zodion Trojan Midi with 32A switch disconnector

Lucy Zodion Results

Lucy Zodion’s isolation solution met all objectives successfully, resulting in a certified and approved installation. As a result of the project, various London Boroughs are closer to meeting their Ultra-Low Emissions targets with a capable infrastructure to support EV drivers. The objectives were met in the following ways:

Safe | Lucy Zodion included in the design a 25A residual current protection for the 5.8kW ubitricity EV chargers. Additionally 6A protection for the luminaires was included so that in the event of a fault on the charging equipment, the luminaire will continue to operate as normal.

Reliable | Lucy Zodion isolators are manufactured considering current British and Industry standards. Components are also tested by third party, KEMA, for further compliance and accreditation. The 32A isolator is KEMA tested to IEC/EN 60947-3 and the fuse carrier is KEMA tested to IEC/EN60269-1. Additionally the isolators’ 25A residual current protection and 6A protection, were integrated in line with the IET Code of Practice for Electrical Vehicle Charging Equipment Installation (BS7671:2008+A3: 2015).

Delivery Time | Due to the number of units required, these were shipped weekly to support a wide-scale roll out over a relatively short period, which suitably matched the installation schedule.

Versatile | The isolators provide 25A residual current and overload protection for ubitricity’s 5.8kW EV chargers, which are mounted into existing streetlights. In addition, 6A protection is included for the luminaires to provide dedicated supply and protection in order to minimise outages. The isolators were used in conjunction with the Network Operators (UKPN) approved Lucy Zodion Street Lighting Cut-Out.

Feeder Pillars | A Survey of External Enclosure Performance By Ritherdon

Feeder Pillars

Feeder Pillars

Water ingress, Corrosion & Paint Finish of Cabinets and Feeder Pillars 

There are many thousands of Ritherdon cabinets and feeder pillars in service and, stainless steel being highly corrosion-resistant, that number is constantly growing.

There are a few enclosures around the UK which we keep an eye on to monitor their performance as they age. Over the years, this has helped improve their design and the materials that we use and this is the reason why Ritherdon external enclosures are among the highest quality on the market.

In May 2021, Ritherdon did a survey of several local pillars and cabinets to see how some of the old ones are doing but also to test that sealing the cabinet base of the enclosure prevents internal condensation and mildew on the backboard.

This report is a photographic summary of what we found.

Water Ingress Protection

Water Ingress Protection

Basic Feeder Pillars

Is it Necessary to Seal the Base?

Plate 1 and 2: R300 Feeder Pillar ~ 10 to 15 years old

It’s probably fair to say that most basic, small feeder pillars (e.g. with just the cut out and protection for a couple of circuits coming out of them) don’t have their bases sealed.

In many cases, where the ground water levels are low, this doesn’t cause a problem.

The electrical components inside this kind of feeder pillar are perhaps relatively less sensitive to humidity and usually housed within their own sub-enclosure, with an added layer of ingress protection.

Plate 2 – R300 (approximately 15-15 years old)

Inside the pillar shown in Plate 2 (R300, approximately 10 to 15 years old), with no base seal, the surfaces felt slightly damp and there were some small signs of mildew on the backboard.

Plate 3: R150 Pillar ~10-15 years old

However, the inside of the feeder pillar in Plate 3 (R150, ~10-15 years old, just a few feet above a river) was very wet. There was condensation running down the sides of the enclosure and the backboard was clearly damp, with some mould growing on it.

The base was unsealed and, most likely because of the high water-table in that location, there was significant water ingress.

Apart from looking unsightly, the marine grade plywood backboard had still maintained its integrity and felt solid after well over a decade in those conditions. Also, as expected, there were no signs of corrosion on the pillar body either.

Plate 3: R150 Pillar ~10-15 years old

Plate 4 and 5: RB460 Metered Pillars ~2 years old

These RB460 cabinets in Plates 4 and 5 had been installed much more recently (probably within one or two years) however the backboard already had a lot of mildew growing on it. The base, while concrete, was not sealed with impervious material (grout or resin) and standing water could be seen in the ducting (Plate 5).

Plate 4: RB460 Metered Pillars ~2 years old

Plate 5: RB460 Metered Pillars ~2 years old

Cabinets with a Sealed Base

Communications Cabinet

When an external enclosure is intended to house more sensitive electrical or electronic equipment it is definitely important to seal the base with an impermeable material.

The CP850 cabinet in Plate 6 is based on the RB cabinet range, with the same door sealing design as the RB460 in Plates 4 and 5. The CP850 is a much deeper cabinet and has internal 19” racking installed.

Plate 6: CP850 Cabinet with Sealed Base

Plate 6: CP850 Cabinet with Sealed Base

The CP850s inspected in this survey all had their bases sealed with resin (and the ducts sealed too).

As a result, the environment inside the enclosures was clearly suitable for the communications equipment they were housing. There was no feel of damp and no sign of mildew on the wooden backboards.

---

Should we Pre-treat the Backboards with Fungicide?

We decided not to treat the backboards of the enclosures we make for the following three reasons:

1. The marine grade plywood boards will maintain their integrity even in very damp conditions for many years (e.g. Plate 3).
2. As an ISO 14001 compliant company we aim to minimise our environmental impact. This includes avoiding the use of potentially harmful chemicals wherever we can. Using fungicides in this way would be contrary to that aim.
3. Water ingress in any external enclosure is clearly undesirable and so Ritherdon recommend that mildew on the backboard should be a clear indicator to the user that the base needs sealing.

If the cabinet is inspected during a dry period, without this visual indicator, the potential problem might not be so obvious. The integrity of the backboard itself will not be significantly affected by the mildew but the equipment housed in the enclosure may be damaged by the damp.

---

Older Pillar Performance – Over 20 years old

Some feeder pillars included in this local survey were over 20 years old.

The backboards of these pillars were not inspected this time but Plates 7 and 8 show the condition of the pillars’ exteriors.

Resistance to Corrosion

Plate 7: R150 ~ 20+ years old

Plate 7: R150 ~ 20+ years old

Plate 7 shows a Ritherdon R150 feeder pillar, installed at the side of an urban road in the late 1990s. Plate 8 is an R460  pillar of similar age installed by a main road, in a rural environment. Both pillars would have been fabricated from standard 4003 grade stainless steel (some further reading on the predicted service life of  different grades of stainless steel from the BSSA).

There was clearly very little corrosion on these 20+ year old feeder pillars, with just some localised staining on bare edges. The powder coating at the base of the R460 has started to peel away in places.

Plate 8: R460 Rural Environment

Plate 8 R460 Rural Environment

Durability of the Paint Finish

This pillar was last surveyed in 2012 when the paint was still intact, suggesting that the powder coating will last for at least 15 to 20 years in rural and urban environments. The bare metal exposed by the peeled coating, was still bright and untarnished.

Ritherdon have switched to ‘architectural grade’ powders in recent years, which should last even longer than the coatings on these early pillars.

---

Conclusions from the Survey of External Enclosure Performance

1. Pillars and Cabinets Designed for Water Ingress Protection Ritherdon enclosures are designed to keep water out (IP 24 with louvres, IP 46 without). So, if you see mildew on the backboard then moisture is likely to be coming up though the base.
2. Signs of Mildew on Backboard Indicate Water Ingress Rather than treat backboard mildew with fungicide, it is better to stop the water entering the enclosure.
3. Seal the Base of Cabinets and Pillars Ritherdon always recommend that you seal the base of your external enclosures. This is a reasonably straight-forward process and can easily be done retrospectively.
4. Long Service Life and Performance Ritherdon stainless steel enclosures perform extremely well in typical, roadside environments; maintaining their integrity and functionality, with even the surface powder coating lasting for at least 15 to 20 years.

Tips To Prevent Your LV Switchboard From Overheating By Comeca Group

Prevent your LV Switchboard from Overheating

LV Switchboards

• Special thanks to Mélanie Oliver at Comeca Group for the kind permission to republish this article

The monitoring of the heat build-up, often carried out by thermography, allows early detection of anomalies that will lead to spurious tripping or even fire and the immobilisation of the installation for a long period. It is therefore a subject that deserves our full attention because it deals with the safety and availability of the installations and therefore the continuity of production.

Thermography is a solution that ensures that there is no abnormal heating of the switchboard during operation.

However, well before its operation, at the time of specification, purchase and installation of the switchboard, there are a few keys factors not to be overlooked.

In the field of high-power, withdrawable, low-voltage switchboards, it is possible to have a positive influence on the future of the installation from the moment of purchase. Similarly, the choice of equipping the switchboard with certain devices allowing easy and safe access to the components to be controlled will make its’ operation simpler and safer.

A good, original design, continuous monitoring and appropriate maintenance are key to the durability and reliability of the electrical panel over the years.

1. Design your LV switchboard according to the IEC 61439-2 standard

A well-designed electrical panel should be chosen, it should be validated in all respects according to IEC 61439-2. Indeed, this standard requires tests and checks to ensure that each component is implemented in accordance with the rules of the standard and that the temperature rise is perfectly controlled, within acceptable limits.

By carrying out these tests, the original manufacturer has the data at its disposal that enables it to produce suitable, reliable and long-lasting low-voltage assemblies, in line with their operating conditions.

Temperature rise tests on an LV switchboard

2. Maintain your LV switchboard regularly

During installation, care should be taken to ensure that the air vents are not obstructed or limited in their effect to ensure natural ventilation of the switchboard.

The cleanliness of the air vents but more generally of the electrical panel should be periodically checked to avoid any degradation of the intrinsic qualities of the assembly. In addition, the forms of internal separation will not be removed, they are the ones which ensure the protection of the personnel during the thermography and maintenance campaigns.

3.Monitor heat build-up by thermography

Thermography campaigns require going as close as possible to, and aiming at, live components. In doing so, the operator will take more risks than during the operation of his switchboard.

In addition to periodic inspections, certain safety features can facilitate or supplement the monitoring of overheating. Discover the safety elements that can be implemented at the time of the initial investment or modernisation of your existing installation.

Easy & Secure Access

Inspection of the cable terminations is a must. Easy access and the width of the cable sheath are criteria to be considered. The position and shape of the downstream power connections are elements that can bring a increased ease of this operation.

For feeders, the possibility of opening the front opening drawer allows all components and all clamping points of the drawer to be seen.

If this option was not chosen at the time of purchase, the starter may have been fitted with a sighting window, which will nevertheless allow some thermal readings to be taken, but in a much smaller sighting area.

Thermographic sighting

The main busbar, which is often placed in the upper position of the switchboard, can also be examined. The main purpose is to check the temperature at the busbar joints and connections. The fewer they are, the fewer points to be monitored.

The roof of the electrical panel must meet certain safety requirements:

• Easy removal of the sheet metal
• Equipment of removable sheets with captive bolts
• Presence of forms of protection

By its’ design, the assembly must facilitate this operation, which is often uncomfortable to carry out because it is high up and close to live elements.

When choosing the LV switchboard, it is therefore important to ensure that it offers a safe and easy access solution for this type of operation.

The power connections on the incoming circuit breaker(s) are also often difficult to access. This is particularly true for switchboards with cable connections from the front. In this case, permanently readable infrared sensors can be offered.

Points of Vigilance for Sighting Devices without Dismantling

For sighting devices without dismantling (arc-proof windows, large arc-proof windows, grids), the solution must allow measurements to be taken without opening the LV switchboard casing and guarantee the protection of the operator during the inspection, thus avoiding the need for reinforced individual protection to protect against the effects of a possible internal arc flash.

The electrical panel can be fitted with these devices on the incoming columns, to monitor the temperature at the main busbar sides or even on the fronts of some withdrawable drawers.

Focus On Viewing Solutions

Polycrystalline sightglasses are the best known solution; they are relatively expensive and offer a fairly narrow viewing surface but promise good internal arc resistance.

Larger sighting solutions of various shapes and sizes are also available. They consist of a honeycomb structure firmly attached to a plastic film. They allow a much better viewing angle and an increased inspection area. Their internal arc resistance is sufficient in many cases and their plastic film does not degrade over time, unlike polycrystals which lose their transparency over part of the spectrum as they age.

In the case of withdrawable drawers, cheaper solutions can be considered, such as the use of Plexiglas or removable metal sheets that allow partial inspection of the interior but with the appropriate individual protection. The use of front opening drawer is the solution allowing a complete inspection of the inside of the drawer but it leads to an increased risk for the operator during the measurement campaign.

Conclusion

In short, a well-designed, well maintained low-voltage switchboard and regular monitoring of its components enable you to prevent the risk of fire resulting from abnormal heating of your installation.

It should be remembered that each intervention requiring the opening of a door or front plate exposes the operator to a greater risk of internal arcing and contact with live parts.

In fact, tests on the behaviour of the electrical panel during an internal arc are always carried out with the enclosure closed and the effects of the arc on the operator are only evaluated outside the LV switchboard during internal arc conditions.

For thermography campaigns, it is necessary that the operator wears adequate individual protection and is trained to follow the appropriate methodology.

Did you know that we will need over 29,000 charging points for Electric Vehicles across Great Britain by 2030? Over 85% of these need to be fast or rapid chargers.

Want to know more about the difference?

Electric Vehicles

Electric vehicles are a key technology to reduce air pollution in densely populated areas and a promising option to contribute to energy diversification and greenhouse gas emissions reduction objectives.

The growing demand for Electric Vehicles (EV) and the resulting strain charging infrastructure has on our electrical network, means a wide range of safe and compliant connection solutions are required. Global sales rose a dramatic 65% from 2017 to 2018, for a total of 2.1 million vehicles. However, the subsequent outbreak of the coronavirus pandemic has resulted in a 25% decline in EV purchases during the first quarter of 2020.

Despite these setbacks, Electric Vehicle demand is again expected to rise with improved batteries and a more readily available charging infrastructure.

From DNO accredited cut-outs and isolators for on-street chargers, through to larger ‘heavy duty’ EV feeder pillars for fast, rapid and super chargers, Lucy Zodion’s products and design team can solve your connection requirements.

Empowering EV with pre-wired solutions

As one of the UK’s leading suppliers of pre-wired power distribution enclosures, we understand the importance of electrical safety and flexibility to meet the growing demands of power infrastructure. EV is becoming commonplace throughout the UK, with a number of initiatives in-place to drive-up use of electric vehicles in a bid to reduce emissions and increase efficiencies. As the demand for EV increases, there becomes a growing need for the implementation of accessible charge points, meaning a step-change in urban infrastructure is required, therefore the demand for power distribution solutions are on the up.

With this in mind Lucy Zodion is able to meet a number of EV power distribution requirements, to meet almost all specifications, configurations and styles.  We have an in-house Design Centre dedicated to the design and manufacture of bespoke power distribution pillars and have extended our service to EV power distribution enclosures, developing solutions to meet growing demand.
