What specialized equipment is essential for constructing high-voltage overhead lines?

2025-08-13

Constructing a high-voltage overhead line is a complex and precise process that requires specialized equipment to ensure both the integrity of the line and the safety of the crew. Key equipment includes:

  • Hydraulic Pullers and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners: These are arguably the most critical machines in the process. They are used to pull and tension the heavy conductors with exceptional precision, ensuring the correct sag is achieved. Our OHTL wire cable conductor tension stringing equipment is specifically engineered for the high tensions required for HV conductors.

  • Conductor Stringing Blocks: These are sheaves mounted on the towers to support the conductor as it's being pulled. They must be robust and have a smooth groove to prevent damage to the conductor's surface, which could lead to corona effect and power loss.

  • Earth Anchors and Winches: Used to anchor and stabilize the heavy towers and poles, especially during the pulling and tensioning phases, where immense forces are exerted on the support structures.

  • Overhead Tools: This includes insulated hot sticks, earthing kits, and a variety of specialized tools for working safely near or on energized lines.

We provide a complete one-stop supply for all these tools and equipment, simplifying procurement for high-voltage projects of any scale.
