GROVE CLAMP PARALLEL 2 BOLT BI METAL AL150MM2-CU95MM2
Bi-Metal Parallel Groove Clamps
CABAC has a range of bi-metal parallel groove clamps for tapping or joining hard drawn orannealed copper conductor to aluminium overhead conductor type AAC, AAAC or ACSR.
Forged from 99.6% pure aluminium, incorporating two parallel grooves with transverse ridgesallowing low resistance between the clamp and conductor.
One parallel groove has a copper inlay impact welded onto the surface of the groove, and theexternal aluminium to copper interface is sealed by a special compound which preventsinterface corrosion.
Slotted bolt holes allow adjustment to varying conductor sizes in each groove.
Tightened onto the conductors using galvanised 8.8mm bolts.
Galvanised nuts allow the clamp to be tightened with the use of a single spanner at highertorques.
Belville washers on bolts maintain clamping pressure, thus preventing metal creep.
Clamps are ultrasonically tested to check bonding between copper inlay and aluminium.
Individually packed in plastic bags.
