HV Substation Clamps – Earth End
PB Weir earth end substation clamps are precision manufactured from a robust aluminium casting with stainless steel fittings. are designed to meet ENA technical specification 41/21.
The sprung loaded feature of all types makes them suitable for application by hand to copper or aluminium earth bars in any natural condition and are suitable for application by hand. Only normal strength is necessary to achieve a good contact and tightness.
Sprung loaded clamps should be tightened down until the spring is fully compressed but not overtightened. Earth end clamps should be fastened securely in place before any attempt is made to secure the line end clamp and should be inspected at 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.
Substation portable earthing clamps suitable for extra high and high voltages: 66kV 132kV 245kV 400kV.
