How to Select the Right Conductors for Overhead and Underground Transmission
Selecting the right conductors for overhead and underground transmission lines is a critical aspect of power system design. Conductors influence the efficiency, reliability, and safety of the transmission network. This article provides a comprehensive guide to selecting suitable conductors for both overhead and underground transmission systems, considering technical parameters, material properties, cost, and environmental factors. 1. Types of Conductors 1.1 Overhead Conductors Overhead transmission lines primarily use bare conductors, which are supported by towers or poles. Common types include: Aluminum Conductor Steel Reinforced (ACSR) : A widely used conductor composed of aluminum strands wrapped around a central steel core. The aluminum provides high conductivity, while the steel core offers mechanical strength. All-Aluminum Alloy Conductor (AAAC) : Made entirely of aluminum alloy, it has better corrosion resistance and mechanical strength than ACSR but lower tensile strength. Aluminum Co…
