The tension clamp is also called dead end clamp or strain clamp, which is used to fix conductor and ground wire on transmission lines or distribution lines, and through link fittings to connect with insulators.
In according to the material, it can be divided into two series: NLL series tension clamp, is made of aluminum alloy, and NLD series, is made of malleable iron.
Depending on the conductor diameter, there are NLD1, NLD2, NLD3 and NLD4.
The clamp body and keepers are malleable iron, the closed -pin is stainless steel, and the others are HDG steel.
