Strain Clamp

Tension clamp is one type of single tension hardware that used for completing the tensional connection on a conductor or cable,
and it provides mechanical support to the insulator and conductor. It is usually used with fitting like clevis and socket eye on
the overhead transmission lines or distribution lines.
Bolted type tension clamp is also called dead end strain clamp or quadrant strain clamp.
Depending on the material, it can be divided into two series: NLL series tension clamp is made of aluminum alloy, while the NLD series is made of malleable iron.
NLL tension clamp can be classified by the conductor diameter, there are NLL-1, NLL-2, NLL-3, NLL-4, NLL-5 (the same for the NLD series).
