Parallel Groove Clamps Copper Extruded type
The clamp was designed to connect two parallel bare conductors . Conductors can be copper stranded or rods .Material is forged copper for copper to copper connection throughout the conductor range .The clamps have serrated transverse grooves for maximum conductor contact ,use coppel bolts and utilise Belleville washers to prevent thermal ratcheting under cyclic loads .
The clamps are coated with an oxide inhibitor .And stainless botls and nuts with washers was on requirement .
For tap-off connections of copper-conductors acc to DIN48201 .
Material
Body：Copper alloy
Bolts：steel or stainless steel
Nuts：DIN 934 ,steel
Surface：uncoated
