High Voltage Substations - Temporary Earthing Kits for Substation Earth Tapes

Thorne & Derrick UK distribute temporary HV earthing kits and equipment for substation earth tapes in accordance with National Grid NSI 24.

Earthing kits for high voltage (HV) substation earth tapes cover National Grid substations (400kV-275kV-132kV), Intermediate substations (66kV-33kV-11kV) and Distribution substations (less than 11kV to 415 volt).

2 types of Earth Tape Bridging HV Kits are available :

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.
