What is the standard procedure for laying 11 kV underground cables?

2025-08-14

The laying of 11 kV underground cables is a multi-step process that requires careful planning and execution. The procedure typically includes:

  • Route Survey and Planning: Identifying the precise cable route, avoiding other utilities, and conducting a geotechnical survey to assess soil conditions.

  • Excavation and Trenching: Digging a trench according to specified dimensions and safety standards.

  • cable laying: Using specialized equipment like cable drum jacks, rollers, and winches to lay the cable smoothly into the trench.

  • Backfilling and Protection: Covering the cable with a protective layer of fine sand or thermal backfill, followed by brick or tile protection, and then restoring the trench.

  • Jointing and Termination: Connecting cable sections and terminating them at switchgear or transformers.

  • Testing and Commissioning: Performing insulation resistance, continuity, and high-voltage tests to ensure the integrity of the installed system.
