What are the primary techniques for pulling large conductors in overhead and underground projects? ⚡
2025-08-15The choice of technique depends on the project's application. For large-scale projects, there are two primary methods:
-
Overhead Tension Stringing: This is the most widely used and safest technique for installing conductors on transmission lines. It involves using a hydraulic puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner to pull the conductor while keeping it continuously suspended above the ground. This method prevents the conductor from dragging, which minimizes damage and maintains a safe ground clearance at all times.
-
underground Pulling in Conduits: For underground power cables, the technique involves a high-capacity pulling machine to draw the cable through a pre-installed duct or conduit. This technique focuses heavily on managing friction and ensuring the cable's integrity as it navigates bends and long distances.
