Application:
The tension clamp of NLL series are generally called bolted type tension clamp or aluminium alloy gun type strain clamp,which are used for fixing aluminium wire or steel core aluminium wire on the strain pole, which apply to aerial line below 220kV.
Advantages:
1.Convenient installation: No need of special tools and cutting the wire
2.Grip and Failure load: Increased as the body and the wedge core of Bolt Type Strain Clamp is made of high strength aluminum alloy materials
3.Features:With Self-locking function to pull the wire tight ,which increasing the safety and reliability of the line and reusable advantage after removing
4.Significant effect:No cutting of the wire brings electrical contact point reduce, low loss, energy-saving of transmission line.
