What Is Pre-twisted Wire?

In the field of modern power transmission, armor rods transmission line, as a key connection hardware, is gradually becoming the "invisible guard" in the transmission line with its high reliability, easy installation and environmental protection advantages.

1. What is armour rod?

armour rod in transmission line is a metal accessory for overhead transmission lines, mainly used for terminal fixation of conductors or ground wires, anchoring of tension sections and jumper connections. Its structure consists of aluminum alloy wire bundles prefabricated in a spiral shape, which are evenly wound on the surface of the conductor to form a tight mechanical grip, replacing traditional bolt crimping or hydraulic armor rods conductor.

2. Technical highlights

Strong fatigue resistance: pre-twisted wires and conductors are in full contact to disperse stress, reduce metal fatigue caused by breeze vibration, and extend the life of the line.

Convenient installation: No hydraulic tools are required, manual winding can be completed, and construction efficiency is increased by more than 50%, especially suitable for complex environments such as mountainous areas and high altitudes.
