How do you prevent mechanical damage to a conductor during overhead line stringing?

2025-08-08

Preventing mechanical damage is a primary concern. It can be achieved by:

  • Proper Equipment Selection: Use OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks and rollers with sheaves made from high-strength, low-friction materials like MC nylon or neoprene-lined aluminum, sized correctly for the conductor.

  • Controlled Tension: Employ hydraulic OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners and pullers to maintain a constant, controlled tension throughout the process, preventing the conductor from dragging on the ground or rubbing against objects.

  • pulling grips: Utilize conductor pulling grips that provide a secure, uniform hold on the cable, distributing the load evenly and avoiding point pressure that can cause damage.
