What does ACSR stand for in electrical cables?

ACSR stands for Aluminum Conductor Steel Reinforced. This designation indicates a specific type of electrical conductor commonly used for overhead power lines. The aluminum conductor provides excellent conductivity, allowing for efficient transmission of electricity, while the steel reinforcement enhances the strength and durability of the conductor, making it suitable for long spans and high-tension applications.

In this configuration, the aluminum wires are wrapped around a central core of steel strands. The steel core offers additional tensile strength, allowing the conductor to withstand environmental stresses, such as wind, ice loads, and physical impacts. This combination of materials allows ACSR cables to be both lightweight and strong, which is essential for supporting the rigors of outdoor installation and operation in power distribution networks.
