Type No.:MAG-Bolted aluminum
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 suitalbe for
aerial line up to 35kV,fixing aluminum wire or steel core minium
wire on the strain pole, aerial insulation aluminium conductor
and insulation aluminium 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
1. The body is made of high-strength
2. Smooth surface long servile life
3. Easy installation
4. No waste electric energy
Insulation Cover Performance Feature
1. Withstand voltage:
≥ 18kV keep voltage one minute not breakdown
2. Insulation resistance:> 1.0×1014Ω
3. Environments temperature:-30℃ ~90℃
4. Weather proof performance:have good performanced after
1008 hoursartifical climate aging test.
