T&D can design and develop portable earthing for use on outdoor high voltage substations, overhead transmission lines and distribution lines – portable earthing kits have been developed to provide safe and secure high voltage connections to dirty or heavilty oxidised copper/aluminium earth bars, stubs or stranded conductors. The earth clamps, operating poles, sockets and cables have safely withstood mechanical and electrical type tests for use on National Grid systems.
