Something about Bare Conductor
What is a Bare Conductor
A bare conductor refers to a metal conductive wire without any insulation layer or outer sheath. It is usually made of copper, aluminum, steel, or other alloys. Because of its excellent heat dissipation, light weight, and low cost, it is widely used in high-voltage overhead transmission lines, substation busbars, and electrified railway systems.
As a fundamental material in power engineering, it is often regarded as the “backbone artery” of power systems.
Types of bare conductor
Application of Bare Conductor
1. High-voltage and ultra-high-voltage overhead transmission lines
2. Busbar system of substation and power distribution equipment
3. Internal connections and special operating conditions of electrical equipment
Advantages and disadvantages of bare conductor
Advantages: Good heat dissipation performance, low cost, lightweight, easy to install, suitable for long-distance power transmission
Disadvantages: No insulation, susceptible to environmental influences, requires a large safety distance, prone to lightning strikes
