Telexc Helical Tension Clamps are designed for secure dead-end termination of OPGW（Optical Fiber Composite Overhead Ground Wire） and ADSS（All-Dielectric Self-Supporting）cable in aerial broadband deployments and communication networks. The system combines preformed dead-end grips with structural reinforcing armor rods to provide effective load transfer while protecting the cable from mechanical damage.
The specially designed armor rods provide cushioning and stress distribution, ensuring that no undue stress is applied to the OPGW or ADSS cable. This design significantly enhances cable system reliability and ensures long service life under continuous tensile and environmental loads.
Helical Tension Sets are mainly used for cables with Rated Tensile Strength (RTS) up to 160 kN, installed on terminal poles/towers, tension poles, corner poles/, and continuation structures.
A complete Telexc OPGW Helical Tension Set includes:
-
Preformed Dead-End Grip (Aluminum alloy / Aluminum-clad steel)
-
Structural Reinforcing (Armor) Rods
-
Thimble, Shackles, Parallel Plates
-
Supporting fittings
-
Grounding wire clamp (supplied together; not installed directly on armor rods or dead-end)

-
IEC 60794
- ISO 9001 / 14001 /45001
Types Available
-
Guy Wire Dead-End Grips: Used for pole guying in communication lines; suitable for steel strand guy wires.
-
Preformed Dead Ends for OPGW / ADSS: Suitable for ADSS/OPGW cable applications where high mechanical holding is required.
Construction & Materials
-
Shackle
Hot-dip galvanized steel; connects to a fastening clamp on tension poles or towers. -
Parallel Plate
Hot-dip galvanized steel; connects the thimble and U-shackle. -
Thimble
Hot-dip galvanized cast steel; installed at the bend of the preformed dead end to protect the cable and provide a secure connection point. -
Armor Rods (Structural Reinforcing Rods)
Manufactured from aluminum-clad steel wires with internal emery particles to increase friction. Supplied in multiple subsets to reduce misalignment and speed up installation. Rod ends are outward-bent to prevent stress concentration on the cable. -
Preformed Dead-End Grip
Made from aluminum-clad steel wire with internal abrasive coating. The helical structure provides high gripping strength while reducing side pressure and eliminating point loading. - Identification: Factory color code and product label
Installation Guide
- Identify the color code on the preformed rods and match it with the cable marking.
-
Install the armor rods first to reinforce and protect the cable.
-
Insert the thimble into the bend of the preformed dead-end grip.
-
Wrap the short leg of the dead-end grip first, followed by the long leg.
-
Continue wrapping manually until the grip is fully seated on the cable.
-
Verify correct installation through visual inspection.
-
No special tools or training are required.
