Telexc Stainless Steel ADSS & OPGW Down Lead Clamps are engineered to securely guide and fix fiber optic cables from transmission towers or poles down to splice boxes or terminal points. Designed for long-term outdoor performance, these clamps ensure stable cable routing without inducing mechanical stress or surface damage.

Manufactured using corrosion-resistant stainless steel, aluminum alloy components, and protective rubber liners, the clamp provides a strong holding force while preserving cable integrity. Its adaptable structure supports a wide cable diameter range, reducing inventory requirements and simplifying field installation.

Telexc down lead clamps are suitable for cement poles, galvanized steel poles, and lattice towers, offering reliable performance in power transmission and telecommunication networks.

International Standard Compliance

IEC 61284:1997
Designed according to international utility hardware best practices
Meets mechanical strength, material durability, and cable protection requirements for overhead fiber installations

Construction & Materials

Main Body: Stainless steel
Mounting Components: Aluminum alloy adapters
Cable Contact Surface: High-performance rubber/urethane pads
Fasteners: Stainless steel bolts, nuts, and bands

This construction ensures long service life in harsh outdoor environments while preventing abrasion or compression damage to optical fibers.

Installation Guide

Confirm clamp position and cable diameter.
Adjust the stainless steel pad according to the cable direction.
Wrap a stainless steel band around a pole or structure.
Secure the band through the aluminum alloy adapter.
Tighten the M12 nut firmly.
Place the cable into the rubber groove.
Close the clamp and secure it with the spring pin and nut.

Installation Notes:

Typical spacing: 1.5 m per set
Two sets are recommended at cable bending points
Install from top to bottom during cable routing

Applications

Power Transmission Lines
Used to guide ADSS and OPGW cables from towers or poles to ground-level equipment while resisting wind, vibration, and thermal movement.

Fiber Optic Communication Networks
Secures vertical fiber routing to maintain alignment and protect optical cables from stress, abrasion, and long-term damage.

Substation Cable Routing
Provides stable and organized cable fixation at substation entry and exit points, reducing strain in high-voltage environments.

Terminal Towers and Splice Joint Towers
Ensures smooth cable transition to splice closures while maintaining proper bend radius and preventing fiber damage.

Angle and Tension Towers
Holds cables firmly at directional change points where mechanical forces are higher, ensuring safe and stable cable positioning.

Utility Poles (Cement & Steel)
Fixes fiber cables securely on poles without drilling, offering long-term protection against environmental exposure.

Telecommunications Infrastructure
Supports reliable fiber routing in broadband and telecom networks by preventing cable movement and signal interruption.

Product Advantages

Ensures Cable Stability
Firmly secures ADSS and OPGW cables to prevent sagging, vibration, and unwanted movement under environmental loads.

Protects Cable Integrity
Rubber-lined contact surfaces reduce abrasion and compression, safeguarding optical fibers from mechanical damage.

Maintains Proper Alignment
Keeps cables correctly positioned during vertical routing, preserving bend radius and preventing stress points.

Enhances Operational Safety
Prevents cables from contacting structures or ground points, reducing the risk of faults and installation hazards.
