Tension Assembly for OPGW

OPGW Suspension / Cable Fittings / Tensioner Assembly

Features
a. The tension assembly for OPGW cable provides uniform stress distribution for maximum cable protection.
b. The cable clamp has outstanding gripping strength, and is able to hold greater tension without exceeding the cable side crushing strength.
c. The grip strength is no less than 95%RTS of optical cable.
d. Excellent aluminum clad steel material to improve the mechanical and corrosion-resistance of the clamp.

Purposes
The tension assembly holds all of the strain of OPGW suspension installations.

Note: Please contact our technical department if selection demand exceeds the technical scope of the table.

Cautions:
a. Select the tension clamp according to OPGW cable diameter and rated tensile strength.
b. Configurations: 1 set/ terminal tower (including gantry), 2 sets/ tension tower.
c. The lay direction of inner rod is opposite that of the lay direction of the OPGW outer wire. The lay direction of OPGW outer wire is right. If left, it should be specified in the order contract.
d. After the clamp affords a full tension, it cannot be loosened.
e. Provide us with the model type of the first link fitting connected to tower in order to get the proper cable fitting.
f. Clamp strength: 70kN, 100kN, 120kN, etc.
