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.The most

popular tension clamps are probably NLL and NLD clamps

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).

NLD series tension clamp is used with aluminum-clad steel conductor. When it is used on the aluminum

conductor, it usually assembled with liners. The above is only introduced the main body of the tension

clamp. There are U bolt, nut, and washers required for fasten the conductors into the gun bodies.

The bolt type of tension clamp is suitable for aerial lines up to 35kv. Jingyoung bolt type tension clamp

is intended for use with ACSR or all-aluminum conductors. Some clients ask NLL series of bolt type

together with the armor tape or special liners to protect the conductor from damage.
