NYH Strain Clamps(Hydraulic Compression Type)

Strain clamps are used to tension conductors and earthwires and must therefore satisfy the most stringent requirements.
 
There are two basic systems of tension clamps, viz:
1. Detachable clamps, such as wedge-type tension clamps, thimbles,bolted type tension clamps, which allow for subsequent adjustment, and
2. Non-detachable clamps, such as compression dead-end clamps which require absolute matching to the conductor length.
