What specific safety precautions must be taken when pulling 11kV cable?
2025-08-16Installing 11kV cable is a high-risk operation that demands strict safety protocols. The primary concerns are the cable's high voltage and its weight. Key precautions include:
-
De-energization and Lockout/Tagout: Before any work begins, the circuit must be de-energized, tested, and properly locked out and tagged out to prevent accidental re-energization.
-
Insulation and Grounding: All personnel must use appropriate personal protective equipment (PPE), including insulated gloves, boots, and tools. Temporary grounding must be installed to safely discharge any residual voltage.
-
Controlling Pulling Tension: Excessive tension can damage the cable's insulation, which can lead to a future catastrophic failure. It is non-negotiable to use a winch with a real-time tensiometer to monitor the pulling force.
-
Proper Handling: The cable must be handled with care to avoid kinking or sharp bends that could compromise its insulation. Proper underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers and sheaves are essential for guiding the cable smoothly through the route.
