preformed grip dead-end grip for ADSS cable
Overview
Tension Clamps are designed to connect ADSS cables and poles/towers . Armor rods can provide protection and cushioning to the ADSS cables. The special design of Preformed rods makes ensure that Tension Clamps can’t cause undue stress to the ADSS cables, so as to ensure the normal lifetime of cables system.

Note
▪ Do not overlap the wire clips. Lapping on the wires before and after the clamp is allowed:
▪ Do not use wire clamps for overhead ground wires;
▪ After the initial installation, do not use the wire clamp again:
▪ The direction of rotation of the wire clamp and the wire should be the same. The standard clamp is right-handed, if you need left-handed products, please consult the company.

Note: The meaning of letters and numbers in the model: N- strain clamp; L- spiral pre-twisted type: “-” is the applicable wire model JY- insulated wire.
The selection of the TCB model of the optional matching hardware is related to the rated breaking force of the wire.
The selection of strain clamp is subject to the actual wire diameter.
