Essential Equipment for Overhead Conductor Pulling (Tension Stringing)
2025-08-16For overhead transmission line projects, a method called tension stringing is used to install conductors. This process keeps the conductor elevated off the ground to prevent damage. This requires a coordinated system of specialized machinery.
-
Hydraulic Pullers: A hydraulic puller is a machine with one or more bullwheels that pull a steel pilot line or conductor at a constant, controlled force. It's the "engine" of the stringing operation, providing the pulling power to install the conductor over long spans.

This prevents the conductor from sagging and touching the ground or other obstacles, ensuring a safe and damage-free installation. Many modern machines, like ours, combine the puller and tensioner into a single unit.
-
Conductor Stringing Blocks: These are pulley-like devices that are installed on tower arms. They guide the conductor along the route and around bends, minimizing friction and protecting the conductor from scrapes or damage.

Hydraulic drum stands & Trailers: These are used to safely lift, support, and unspool large conductor reels. They ensure the conductor feeds smoothly into the tensioner or puller.
