Double earth clamps
For structural steel up to 20mm thick
Earth clamps are used as earth connectors for substations grouding and earthing uplink networks. The quality of an equipotential earthing network depends on the quality of the constituent elements connections, by providing reliable mechanical characteristics and electrical contact as well as good resistance to corrosion. In this context, the earth clamps constitute the connections of the buried mesh network risers to frames, equipment support frames, and, in general, to metallic masses present in substations.
MALTEP offers a range of double winged earth clamps. These clamps are similar to the winged earth clamp but include an additional copper alloy block allowing the mounting of an extra conductor.
The earth clamps are generally mounted on galvanized steel, metalized or aluminum frames. The steel-copper, aluminum-copper or zinc-copper contact generates an electrolytic corrosion. In order to overcome this effect, MALTEP offers brass bolts (stainless steel as standard) as well as bimetallic plates and washers, or clamps in tinned version.
