The installation of 66kV cables presents several challenges that require careful planning and execution. The primary challenges are preventing mechanical damage to the cable sheath and managing thermal performance. Excessive pulling tension, tight bends, or abrasive surfaces can cause microfractures in the cable sheath, leading to insulation failure.

To address these challenges, the following safety precautions are essential:

• Use of Proper Equipment: Always use calibrated winches with real-time tension monitoring to stay within the manufacturer's specified pulling force limits.

• Adhering to Bending Radius: The minimum bending radius of the cable must be strictly followed to avoid damaging the insulation and conductors.

• Professional Supervision: A qualified and experienced supervising engineer must oversee the entire process to ensure all standards and procedures are followed.

• Site Preparation: The cable route must be thoroughly inspected for any obstructions or sharp objects that could damage the cable.
