Electric Vehicles | Power Distribution By Lucy Zodion
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 Zodionis 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. The benefits of our service include:
Case-for-case approach to EV power distribution projects to ensure we meet your specification objectives
In-house Design Centre to ensure approved drawings are closely followed and tested for functionality, fit and form, based on drawings
IET and BS industry standards followed to ensure product suitability and conformity at application
Reaching the streets with on-street connection products
As plans for the ‘Road to Zero’ become clearer, transport has been identified as a key focus to ensure the nation is able to meet its net zero targets by 2050. As a result, a range of Governmental initiatives have been introduced to drive the uptake of electric vehicles (EV). One of these initiatives is to make on-street EV charging more accessible to residents without access to private charging facilities, with £2.5 million funding to be made available for the provision of over 1,000 on-street electric car charge points.
On-street charging can be provided by either street-side charge points, or via transforming existing street furniture into charging hubs; such as lampposts. As a specialist in the street lighting industry for over 50 years, we have a wealth of knowledge in the electrical infrastructure and equipment necessary to provide effective and safe illumination. This knowledge means that we can develop connected, adaptive and reliable solutions to meet the growing demand for on-street EV charging.e nation is able to meet its net zero targets by 2050.

Swapping a faulty power cable for a 1 x 70mm 2 core FGT Aluminium
1 x 70mm 2 core FGT Aluminium
Amaro Signalling Ltd | by Lee Fisher
A few weeks, our guys were getting some well-earned rest after a seriously tough shift in South East London…
A physically demanding job, they’d been tasked with pulling 300 metres of cable between two location cases at Plumstead Station, swapping out a faulty power cable with brand-new 70mm 2-cored FGT cable.
Lee Fisher Assistant Project Manager at Amaro Signalling Ltd commentated on Linkedin, ‘this was 1 x 70mm 2 core FGT Aluminium (water blocked). We have installed a wide range of FGT from 10mm up to 95mm.’
Part of the largest third rail network in the world, the bright yellow ‘third rail shrouds’ you see here proved essential, protecting our team from the 750v of DC power coursing through the conductor rail directly behind them.
Yet another cable installed and ready for commissioning. Keep up the good work!

Stokbord® Drum By Centriforce
Protection of High Voltage Electricity Cables
Centriforce, working through their distributor network including Thorne & Derrick, last year announced a new cable protection product that can help to improve working safety for High Voltage Electricity Cables applications – known as the Stokbord® Drum.
The multinational energy company SSE has launched a network upgrade programme set to future-proof the local electricity infrastructure for homes and businesses of Petersfield, Fernhurst and the surrounding areas.
Through cable network upgrades and the refurbishment of an established substation, SSE’s work will prepare the network for future commercial and residential connections.
Born from our policy for innovation and continuous improvement, Stokbord® Drum is a faster and safer alternative to traditional buried cable and pipeline protection. Stokbord® Drum is a single material strip supplied on an industrial reel which, to install, is simply unwound into the trench removing the need for operatives to set foot below ground.
Suitable for high impact protection against heavy-duty tooling and machinery, Centriforce manufactures Stokbord® Drum to the same industry standards as our globally trusted Stokbord® Cover. The installation time and cost benefits gained through this innovation makes Stokbord® Drum the perfect partner for large scale utility projects.
An excellent example of Stokbord® Drum’s project versatility
Stokbord® Drum has also been installed on major infrastructure projects including: Triton Knoll, Hornsea 2, Dogger Bank
Key benefits of Stokbord Drum
Stokbord® Drum offers a range of key benefits to constructors and end-users including:
Time and cost saving – Stokbord® Drum significantly reduces installation time in comparison to traditional cable protection, up to 5x faster than alternatives
Reduced Risk – Helps to reduce potential risks posed to operatives by reducing the need to enter the trench
Industry Specifications – Stokbord Drum complies with all UK and international industry specifications
High impact resistance – Meets the same standards as Stokbord® Cable Cover – Stokbord® Drum does not shatter on impact from heavy-duty tooling and machinery
Highly visible – Stokbord® Drum uses bright colours and bold text to provide a clear visual warning to workers and excavators on-site
Long-lasting – Rot resistant and chemically inert to ensure the product’s long service life
