What are the main steps and equipment for underground conductor installation?

2025-08-16

underground cable installation is a precise operation focused on protecting the cable from damage as it's pulled through a confined space.

  1. Trenching and Conduit Laying: A trench is dug, and a protective conduit (often PVC or HDPE) is laid inside.

  2. Cable Pulling: A hydraulic cable puller is set up at one end of the conduit. A pulling line is fed through the conduit and attached to the cable using a wire mesh pulling grip and a Swivel.

  3. Controlled Pulling: The puller then draws the cable through the conduit. underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers are used at entry points and bends to minimize friction and prevent damage to the cable's outer sheath. The puller's integrated tension monitor ensures the force remains within safe limits.

  4. Splicing and Termination: Once the cable is in place, sections are joined together, and the ends are terminated for connection to the grid.

Key Equipment:

  • Hydraulic Cable Pullers: To provide controlled, measurable pulling force.

  • Cable drum stands & Trailers: For safely supporting and unspooling heavy cable reels.

  • Duct Rodders: To initially feed the pulling line through the conduit.

  • Wire Mesh pulling grips & Swivels: For a secure, yet flexible, connection.

  • cable rollers and Guides: To reduce friction and protect the cable.
