Helical Tension Clamp

A Helical Tension Clamp is used for fixing OPGW at the corner tower or terminal tower.

Usage scenarios

Communication system

Technical features

The helical structure distributes the stress evenly.

Product advantages

The holding strength of the dead-end set is high, which is not less than 95% RTS of cable;
It has an excellent anti-fatigue characteristic;
The installation is convenient, no special tools are needed;
The inside of the inner and outer rods are covered with silicon carbide, increasing friction.

Remark: AAAA is the largest integer tens within the 95% RTS range, **** is the diameter of OPGW, if stranding direction is left hand, we normally add “S” at the end of type.

For example, OPGW diameter: 13.20mm, RTS=76.5kN, right hand, the type is: ON-080-1320;OPGW diameter: 14.40mm, RTS=118kN, left hand, the type is: ON-120-1440S.
