Portable Earthing - Substation, Overhead Transmission & Distribution Lines

Portable Earthing

Transmission Line Earthing

Substation Line Earthing

Distribution Line Earthing

Portable earthing equipment is specifically for maintenance on high voltage networks to provide safe and reliable earth clamping where electrical connections are to be made to dirty or heavily oxidised copper/aluminium bars or stubs : this includes portable earthing for 33kV, 66kV, 132kV, 275kV and 400kV including line end clamps and earth end clamps.

Portable earthing equipment is electrical safety equipment used for discharging and grounding of de-energised electrical equipment, including high voltage transformers, substations, 11-33kV cable ends and overhead lines.

Portable Earthing Kit - Selection Check List

In order to correctly specify the suitable portable earthing kits it is important to establish the clamping requirement at both ends of the earthing lead i.e. busbar or cable (including dimensions).

• Confirm short circuit rating
• Number of earth leads
• Earth lead lengths
• Current rating
• Voltage
• Confirm operating pole length
