Electric Power Line Fitting Bolt Type Strain Tension Clamp

Aluminum Alloy Bolted Type Dead End Tension Clamp
Bolted type tension clamps are used in transmission line construction with all aluminum, ACSR or aluminum alloy conductor. Consequently it is always necessary to give the exact data concerning conductor and stresses. With this clamp type the conductor can be passed onwards uncut. Fitting is extremely simple by tightening the clamp bolts to the prescribed tightening torque.Application
NLL series aluminum alloy strain clamp (Bolt type) is suitable for aerial line up to 35V, fixing aluminum wire or steel core aluminum wire on the strain pole, aerial insulation aluminum conductor and insulation aluminum cover are being used together, and the action is insulation protection.
The product body and press plate are made of high strength aluminum through heat treatment; the outside shield was made from good climate resistance insulating material.
This product has advantage such as high strength, good holding power, light in weight and no magnetic hysteresis loss, it was belonging to power-saving anchor clamp.Structure Feature
