What are the main components and equipment used for 400 kV overhead transmission line construction?

2025-08-12

A 400 kV overhead transmission line project requires a wide range of specialized equipment. As a leading manufacturer, we provide the following:

  • Conductors: Bundled conductors, such as ACSR (Aluminum Conductor Steel Reinforced), are essential for efficient power transmission.

  • Insulators and Hardware: High-strength insulators, including porcelain or polymer types, along with associated hardware like clamps, tension sets, and suspension assemblies.

  • Tower Structures: The physical support for the line, often large steel lattice towers designed to handle significant mechanical loads.

  • Stringing Equipment: Specialized hydraulic pullers, OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners, and conductor carts are used to safely and precisely install the conductors. For 400 kV, this equipment must be robust enough for multi-bundled conductors.
