P&B Weir Electrical design and manufacture a large range of Substation Portable Earthing equipment for many applications.
The design of all line end clamps is such that once hooked over the bus bar they become self- supporting whilst the operating screw is tightened or loosened.
Portable Earthing clamps should be inspected at regular intervals and prior to each application. All clamps should operate freely and moving parts should be lightly lubricated, springs should be protected by heavy grease and contact faces should be clean.
