What are the best practices for protecting MV cable during the pulling process?
2025-08-15Protecting the integrity of the MV cable is non-negotiable. Following these best practices will prevent costly damage:
-
Use Cable Lubricants: Applying a manufacturer-approved cable lubricant is essential to reduce the coefficient of friction, which in turn lowers the required pulling force and minimizes the risk of overheating and damage.
-
Maintain Minimum Bending Radius: Every MV cable has a minimum bending radius specified by the manufacturer. Our rollers and sheaves are designed with large diameters to help maintain this radius, especially at bends and turns, to prevent cracking of the insulation or shield.
-
Proper Reel Setup: The cable drum must be set up on a stable stand and the cable should be paid out in a straight line or over a feeding sheave to avoid reverse bends or kinks.
-
Avoid Over-Tensioning: As mentioned above, continuously monitoring the tension is the most important practice. The maximum pulling force should always be based on the cable's specifications and never exceeded.
