How To Protect LV MV Cables From Electrical Arc Faults & Fire

June 2nd, 2020

3M Scotch 77 Arc Faults & Fire Proofing Tapes

Electrical Arc Faults

Electrical arc fault generated fires can be of up to 2000 Degrees Fahrenheit.

That’s more than twice as hot as the temperature of the surface of Venus and enough heat to melt gold.

Furthermore, this is more than enough to destroy expensive electrical cables.

The resulting catastrophes of an electrical arc fault generated fire means that we have to find a solution to protect cables against these dangerous and damaging fires.

In this Article we show how 3M Scotch® Fire Retardant Electric Arc Proofing Tape 77, can protect low (LV) and medium voltage (MV) electrical cables from electrical arc faults and their resulting fires.

Arc Faults Can Be Catastrophic

Protecting cables From ARC Faults

with 3m scotch 77 tape

3M Scotch 77 Tapes Even after a short exposure to a flame, an unprotected cable will catch fire, and continue to burn. Increasing the likely-hood of causing other fires and causing additional major damage. One fire could wreak absolute havoc on cables, or the equipment they are connecting.

Unless of course you can help prevent them from catching fire in the first place. Scotch fire retardant electric arc proofing tape, is designed to protect Low Voltage and Medium Voltage cables and cable accessories from arc faults and the resulting fires.

3M Scotch 77 tape can withstand a 2000 degree torch blast from 3 inches away, for 3 minutes.

That’s 3 minutes longer than an unprotected cable.

3M Scotch 77 Tapes are 0.76mm thick, arc and fireproofing electrical tapes designed to protect all types of electrical cables. This insulating firewall acts as a heat shield and flame barrier, thus protecting the cables joints and accessories.

Scotch 77 tape is burn resistant.

It will also help prevent cable jacket material from melting and dripping flames onto whatever lies beneath it. When the flame is taken away from a cable protected by 77 tape, that’s it, it doesn’t continue burning. It doesn’t cause additional fires and when the tape is removed, the cable underneath does not show any significant damage, and should not need to be replaced.

That kind of trusted protection is why electrical professionals around the globe have taken notice. Used properly, Scotch brand fire retardant electric arc proofing tape 77, can be the difference between a small problem, and an expensive catastrophe.

LED Lighting for Offshore Wind Farms

LED Lighting

Raytec are world leaders in LED lighting for hazardous area environments – the Raytec SPARTAN range of hazardous area lighting is globally certified Ex LED lighting, approved for all ATEX and IEC Ex Zone 1 and Zone 2 hazardous area environments, including UL /CSA C1D2 (Class 1 Division 2) installations.

In this Application Focus, we explore the lighting requirements for offshore wind farms and identify some of the key features to consider when specifying luminaires for these types of environments.

LED Lighting Requirements

for Offshore Wind Farms

An offshore wind farm can be defined as a cluster of wind turbines constructed in a body of water. The turbines harvest wind energy to generate electricity and benefit from the high wind speeds of their offshore location.

However, the nature of an offshore location provides a challenging environment when specifying lighting. Given the continuous exposure to marine conditions, such as high wind speeds and a saline environment, a high-quality and durable lighting system, capable of withstanding these elements, is critical.

Offshore Wind Stats

Typical Areas Requiring LED Lighting

Jacket Base Of The Turbine

A turbine sits on a supporting structure called a Jacket Base. The jacket sits above the waterline, as well as being anchored to the seabed, giving the turbine the foundation it needs to withstand the harsh marine environment and dynamic loads.

Lighting, particularly LED lighting, is required to ensure safe working conditions when accessing and departing the turbine, via a crew transfer vessel, where the jacket structure is the main access point. Installing lighting here is also beneficial for routine maintenance and inspection of the area around the ‘splash zone’, where corrosion occurs due to the meeting of the waves and air.

Interior Of The Turbine
Lighting is required inside the turbine for the safety of workers when they perform routine maintenance procedures from within the tower. In many cases ‘Emergency Lighting’, such as the Raytec SPARTAN Intelligent Emergency, is also needed to maintain safety in the event of a power outage.

Access Area Lighting
It is a necessity for heavy-duty industrial lighting to be installed at the crew access point to the turbine, when disembarking the crew transfer vessels. This area sits above the supportive structure and is accessed via a bridge from the crew transfer vessels. Therefore, safety requirements dictate that high-quality industrial lighting is needed to make sure these areas are well lit.

All of these areas require the use of a heavy-duty lighting fitting, such as lighting from the Raytec SPARTAN range, to withstand the challenges of the offshore environment. The remainder of this article will explore the key features to consider when specifying a luminaire for an offshore wind farm.

Specifying Lighting for Offshore Wind Farms

Choosing LED

Firstly, selecting lighting which uses LED technology (rather than conventional lighting, such as high-pressure sodium), should be considered essential when specifying for offshore wind farms.

Lighting Maintenance
Providing it uses effective thermal management, an LED luminaire can offer a lifetime of 100,000 + operating hours, without the need to re-lamp. This results in a significantly longer lifespan and lower life-cycle costs. Reducing the number of maintenance interventions in these remote and offshore locations, where access is difficult and costly, is vital.

Energy Costs
Keeping costs to a minimum is a common goal amongst offshore wind applications. LEDs run more efficiently than conventional lighting; reducing energy costs. The major benefit comes from an LED luminaire’s ability to instantly restrike. Instant restrike allows the lights to be easily switched on and off when they’re not being used. In contrast, due to the warm-up time of a conventional lamp (such as High-Pressure Sodium) they would likely be left switched on 24/7 to avoid costly and impractical delays during maintenance.

Quality of Light
With LED’s capable of providing improved CRI and higher colour temperatures than conventional lighting, light quality is improved which drastically improves working conditions.

Easy Maintenance

Specifying LED lighting can help in reducing the frequency of maintenance required. However, the way a manufacturer has designed the luminaire can have a large impact on how easily maintenance can be carried out of it is required, and how long the site is left without light.

Making Access Easier
For offshore wind farms, where access for maintenance can be difficult, choosing an LED luminaire with a removable power supply unit (PSU), that can be placed separately from the main unit, can help make access easier. For example, Raytec’s SPARTAN High-Power Flood & High-Power Bay luminaires, allow the PSU module to be removed from the main body of the luminaire and be positioned in an easy to access location. This makes access to serviceable parts far easier.

SPARTAN High-Power Bay Lighting

SPARTAN High-Power Flood Lighting

Lighting is required inside the interior of the turbine, stretching from the bottom to the top. Each luminaire can be accessed via a stair or lift system within the turbine column. However, when routine or emergency maintenance is required, having the PSU located at ground level would mean this could be conducted with more efficiency. Having this functionality reduces the time taken to carry out maintenance, and its associated cost. By reducing the time and frequency which maintenance workers spend working at height, health and safety compliance is also positively impacted.

Reducing Downtime
Minimising downtime is crucial to the financial viability of wind farms. If the lighting fails, certain scheduled maintenance procedures can’t take place due to the health and safety risks to the workers.

This could have a detrimental impact on the ‘up-time’ of the turbine itself. So, having a lighting solution that allows maintenance to be quick and easy – bringing the turbine back into service as soon as possible – can be a massive selling point for manufacturers, developers and investors, as this improves the overall financial viability of the site.

LED Lighting For Offshore Wind Farms

Durability

Lighting Withstanding Harsh Environments In Offshore Wind Applications

There are many environmental issues companies need to be aware of when installing hardware for an offshore wind application. These will be discussed in further detail below:

Sea Water (Saline Environments)
A saline environment (exposure to sea water spray and salt water saturated air) can cause a higher risk of corrosion compared to inland applications. Saltwater spray aggressively corrodes the metal. Once evaporated, saltwater can also leave a thin film of salt on the hardware – interfering with the performance of the luminaire by reducing light intensity.

Any luminaire installed in these offshore locations needs to withstand these aggressive conditions. The Raytec SPARTAN range is designed with offshore use in-mind. Made with marine-grade aluminium and stainless-steel fixings, while being ABS approved to marine standards, our luminaires are ideal for any marine application.

Top Tip for Specifying…. Specify a luminaire made from marine grade aluminium or stainless steel as this provides a more robust solution under aggressive environmental conditions. Also look for a luminaire which uses a smaller front gasket, reducing the risk of water ingress into the unit.

High Wind Speeds & Extreme Weather
High wind speeds and other weather conditions such as sleet, hale and heavy rains are a regular occurrence for offshore applications. A luminaire with a high IP rating is essential to prevent water ingress which could damage internal components of the unit.Fixing centres and brackets of luminaires also need to be durable enough to withstand the extra wind forces. If this is not the case, then over time the lighting bracket could wear and snap causing the unit to be lost at sea.

Top Tip for Specifying… Specify a luminaire with an appropriate IP rating, and check exactly which tests the luminaire has been exposed to. SPARTAN lights have been approved to both IP66 and IP67 standards – so they can withstand powerful water jets (IP66) as well as temporary immersion (IP67).

Sun & UV Exposure
Prolonged exposure to the sun, or UV (ultraviolet) rays, is common for offshore locations. In the case of an offshore wind turbine, the turbine is in a vast, open space, with nothing to shadow the turbine. When lighting is installed in external areas, such as the ‘jacket base’, this continuous exposure to UV may cause issues for some luminaires, depending on the materials it’s constructed from. For example, luminaires made from GRP (glass reinforced plastic) can degrade and become brittle when exposed to UV over long periods, causing issues around maintenance and structural integrity of the housing.

Emergency Lighting

Offshore wind sites are high-risk environments and rely on the use of emergency lighting to ensure the safety of maintenance workers on-site at that specific time.

Turbines have a tendency to cut out. This can be down to several reasons, such as the wind speed being too high, water entering the wiring system, a voltage or current surge, or overheating. In these circumstances the turbine is turned off, the fault assessed, repaired, and restarted. This can sometimes be done remotely, but in many cases, it is necessary for people to enter the turbine to manually check the issue. Emergency backup lighting is therefore a necessity to maintain the safety of anyone on site, providing back-up illumination in the event of a power outage. This protects maintenance workers and can be essential in getting the turbine running again. Emergency lighting may also be needed to evacuate people from site if issues are unable to be resolved.

Duration & Output
To ensure an emergency luminaire will provide back-up illumination for the required length of time, it is important to check the emergency duration when specifying. Consideration should also be given to the level of light output the luminaire provides whilst operating in emergency mode. This is usually expressed as a percentage of the luminaire’s output in normal operation, and it is common for output to drop significantly when in emergency mode.

Most of Raytec’s SPARTAN emergency luminaires provide 25% light output for 3 hours as standard but can also offer up to 100% output for a shorter duration if required. The duration and intensity of output are often specific to individual applications, so this flexibility can be an important benefit.

Automated Testing
Some manufacturers are now providing emergency luminaires which increase safety and reliability of emergency systems. Raytec’s SPARTAN Intelligent Emergency luminaires provide a self-testing function which automatically cycles the emergency battery, to maintain its health and to measure its capacity. This ensures the luminaire is operating at its optimum and reduces the requirement for manual intervention. Inspection of emergency luminaires is also made easier, with a tri-colour LED indicator which communicates when the unit is going through a testing procedure and highlighting the health of the luminaire.

BAND-IT Ball-Lok Metal Cable Ties

Essential. Everywhere. Together.

The BAND-IT Ball-Lok range of stainless steel cable ties provide fast and reliable bundling of LV MV HV cables for maximum strength, reliability and clamping of cables.

The corrosion resistant stainless cable steel ties with self-locking design are used to bundle, tie or fasten cables in both onshore and offshore locations including industrial, substation and hazardous area locations with potentially explosive atmospheres.

Several developers and installers of solar farms specify BAND-IT cable ties for a better solution that matches the lifespan of the photovoltaic panels and replaces nylon cable ties with Ball-Lok cable ties as part of their cable management portfolio.

The decision has been by many solar farms to replace the nylon ties with BAND-IT metal cable ties to reduce maintenance and costly failures.

Currently there are over 2,000 solar farms (over 10 MW) planned throughout the United States. The average livespan of a photovoltaic panel is 20 years, which is much longer than the lifespan of a traditional nylon cable tie, especially in extreme heat and UV exposure typically found in high producing solar areas.
