Strain clamps are used to fix conductors and ground wires to insulators or link fittings to tower arms and substation structures.
There are two basic systems of 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.
The type of strain clamps are including NLL-1, NLL-2, NLL-3, NLL-4 and so on.
