Product Introduction

High Voltage Cable Overview

High-voltage cable is a kind of power cable, mostly used for power transmission and distribution, with a voltage level of 35kv-220kv cable. Such as high-voltage overhead power lines and underground power cables.

Construction Details

A typical high-voltage cable construction consists of:
- Core
- Inner insulation layer
- Semiconductor layer
- Steel armor
- Filler material
- Outer insulation layer

Materials used in the cables vary by purpose, but cores are typically copper or aluminum (aluminum being more common due to cost).

Product Features

  • Long service life (30+ years)
  • Suitable for various installations (outdoors, underground, in water, power stations, wind farms, industrial, submarine transmission)
  • Used in electrostatic painting, electrostatic beneficiation, static flocking, and other weak current high voltage DC devices
