What are the key safety considerations and best practices for underground cable laying?

2025-08-14

Safety is paramount in all electrical work, especially with underground cable projects. Key considerations include:

  • Utility Mapping: Before any excavation, conduct a thorough survey to locate and mark all existing underground utilities (gas, water, telecom, etc.) to prevent accidental damage.

  • Proper Trenching: Trenches must be dug to the appropriate depth and width according to local regulations and the cable's voltage.

  • Cable Protection: Use appropriate bedding (a layer of sand) and mechanical protection (tiles or marker tape) to shield the cable from sharp objects and warn future excavators of its presence.

  • Proper Equipment: Use specialized equipment such as cable rollers, winches with tension control, and drum jacks to handle and install cables correctly, preventing damage from excessive pulling tension or tight bending radii.
