Aluminum Heavy Duty Parallel Clamps
Type AVT
• Top and bottom castings are manufactured from high strength aluminum alloy • Spacer is manufactured from pure high conductivity aluminum alloy • Recommended for heavy duty dissimilar metal applications • Accommodates a range of aluminum, copper, and ACSR conductors in either groove (place aluminum above copper)+ • Specially designed wrap-around finger on spacer minimizes cold flow over entire conductor range • Rounded contours for easy taping • Staking the longer of the two bolts makes the assembly one unit with no loose parts to drop • Use of an oxide inhibitor is recommended for aluminum and ACSR installations
