The Double Suspension Helical Set for OPGW is engineered to provide reliable mechanical support for optical ground wire installations on transmission lines with large spans, high elevation differences, and line angles exceeding 30°.
By utilizing a dual-suspension point design combined with inner structural reinforcing rods and outer armor rods, the assembly evenly distributes mechanical stress along the OPGW cable. This design significantly reduces static load concentration and dynamic stress caused by aeolian vibration, thereby improving fatigue resistance and extending the cable’s service life.
The set is widely used on straight-line towers and poles where enhanced holding strength, vibration control, and grounding continuity are required. High-strength double suspension helical set for OPGW, designed for large spans, high angles, and long-term cable protection.

Installation Guide
-
Verify OPGW diameter and select the correct TCLS model
-
Install structural reinforcing rods over the cable
-
Apply outer armor rods evenly in a preformed direction
-
Mount dual suspension housings onto the armor rods
-
Connect the PS links, yoke plate, and U-clevis to the tower hardware
-
Secure grounding clamps and verify electrical continuity
Trained line technicians should perform installation.
