Bolt Type Strain Clamp

NLL series aluminum alloy  strain clamp (Bolt type)is suitable for aerial line up to 35KV,fixing aluminum wire or steel core aluminium wire on the strain pole,aerial insulation aluminum conductor and insulation aluminum cover are being used together action is insulation protection.

There are two basic systems of Compression strain clamps,

1. Detachable clamps, such as wedge-type tension clamps, thimbles, bolted type tension clamps, which allow for subsequent adjustment.

2. Non-detachable clamps, such as compression dead-end clamps which require absolute matching to the conductor length.
