There have always been situations where electrical supplies have to be terminated at the roadside to feed local authority, utility and motorway equipment. Generally the enclosures are metal and in the event of an electrical fault or vandalism there have been instances where the cabinet becomes live and a hazard. There are many recorded incidents where humans and animals are injured after touching live roadside equipment that have developed an electrical fault.
SafeCab is designed to stand up to the hardships of roadside use and is manufactured from stainless steel and Electrically Insulated Coating (EIC) technology to provide a level of protection from touch potential electrocution. The doors and external body are coated with EIC so that in the event of a live electrical fault, access can still be gained safely to isolate the enclosure from the mains supply by the engineer.
Touch Potential Enclosures
The range of SafeCabs are CE approved for installation on DNO supplies and has been extensively tested for working voltage insulation. The units have also been tested to withstand the harshest of environments and have a high chip and abrasion resistance including electrical fire performance.
Manufactured from a unique coating technology the life expectancy for the SafeCab exceeds 40 years and is UV stable for the duration of the product. Stainless steel, coupled with the unique coating system, will extend the life of the SafeCab and save money on future DNO connections and excavations. The units are supplied on a removable plinth for changing of the cabinet in the event of damage and include electrically insulated hinges and locks for non-conductivity if the cabinet goes live.
Until now the only way an engineer could specify an electrical safe enclosure was to use GRP or plastic which can be expensive to mould, brittle and easily damaged by fire and vandalism. With this in mind Henry Williams have developed a roadside enclosure that offers all the strength benefits of a metal cabinet but with electrical insulation, graffiti and anti-fly poster resistance through a unique coating system.
Class II Fully Insulated Enclosures
Transport agency customers have used this solution on their existing roadside communications power cabinets and trackside distribution equipment to achieve a Class II level of insulation. Small modifications to the original designs were undertaken which enabled them to still use major components and reduce the risk and cost which is normally associated with new type approved products.
All SafeCab Class II roadside enclosures are fully certified before leaving the factory and have been dielectric tested to BS EN 61439-1:2011 and are suitable for single and three phase connections. They are manufactured in black and grey as a standard, other colours are available on request. Locks and hinges are fully insulated and the enclosures come with non-conductible fixings, label mounts and internal parts.
