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 single earth clamps. These clamps provides a copper alloy block to maintain the conductor the uplink loop of the buried grounding network.
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.
