NLL Series aluminum alloy strain clamp 


The details of strain clamp: 

The strain clamps is used for fixing conduct wires and linghting rods on nonlinear pole of aerial electric lines or in transforming stations. They are connected to the stain insulators by connecting clamp. Or fix lightning rods on the pole tower.

According to the structures and installation methods, they are divided into three types including bolt type, compressed type and wedge type.

According to different materials, they can be divided into two types: Forging cast iron and aluminum alloy of which, the aluminum alloy clamp is also the energy saving anchor clamp. 

Used for: 

NLL series is suitable for aerial line up to 35KV, fixing alumium wire or steel core aluminum wire on the strain pole.

Specified Failing load of NLL series bolt type strain clamp is from 40KN to 120KN.
