What are the essential safety requirements and best practices for laying cables in a trench?

2025-08-14

Safety is our top priority. The key best practices for underground cable laying include:

  • Thorough Planning: Before any excavation, a comprehensive utility detection and mapping process must be performed using ground-penetrating radar (GPR) or other locators to identify existing underground services.

  • Proper Trench Design: Trenches must be of sufficient depth and width, with stable walls, to prevent collapse.

  • Personal Protective Equipment (PPE): All workers must use appropriate PPE, including hard hats, insulated gloves and boots, and high-visibility clothing.

  • Correct Equipment Usage: Utilize specialized equipment like cable drum jacks, cable rollers, and pulling winches with tension monitoring systems to ensure that the maximum pulling tension is not exceeded, preventing cable damage and ensuring worker safety.

  • Grounding and Bonding: Proper grounding and bonding are crucial to prevent electrical shock.

  • Post-Installation Testing: Conduct thorough electrical testing, such as insulation resistance and continuity testing, before energizing the cables.
