Earthing clamps with scraping plate


Category:

The manual earthing clamps with scrapping plate are manufactured in two sizes (normal/reduced), depending on the value of the nominal short-circuiting current.

By mounting the earthing clamp with scraping plate removes the oxides layers, impurities and protective paint from painted metallic surfaces of poles or earthing bars. This way an appropriate contact resistance is obtained.

The earthing clamps body is made of moulded cooper-aluminum alloy.

The scraping plate and the tightening screw are made of galvanized steel.
