Professional Answer: Pulling high-voltage (HV) cables in substations presents unique challenges due to limited space, critical infrastructure, and stringent safety requirements. Key issues include maintaining the cable's minimum bending radius, managing sidewall pressure at turns, and controlling maximum pulling tension to prevent damage to the cable's insulation and shielding. Overcoming these requires meticulous pre-planning, including route design, proper cable reel handling, and the use of specialized equipment. Our hydraulic pullers and tensioners provide precise control over pulling force, while our a wide variety of cable rollers and sheaves ensure the cable's integrity is maintained, particularly at bends and transitions.
