International Castings offers complete range of envelope design clamps from 6 mm dia to 55 mm diameter conductor. Clamp bodies and keeper pieces are cast in high strength copper free Al-Si Alloy and are also made in other alloys , heat-treated depending upon strength requirement. The U-bolt and clevis pins are of galvanized steel while split pins are of either brass or stainless steel. These clamps offer minimum power loss and heating due to hysteresis effect at higher currents.
Bolted tension clamps are available in Aluminium alloy for all conductor & earthwire sizes. Compression type clamps are recommended for higher strengths requirements.
Socket ended clamps are also available also for sizes upto 100 sq.mm.
Available for EHV lines for corona free performances in multiple conductor systems. Spacers are available for flexible, rigid and armour grip type applications. Products are designed to withstand tensile, slip, mechanical, compressive and fatigue endurance for longitudinal, horizontal and subspan oscillations including short circuit forces.
