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…
