What does ACSR stand for in electrical engineering?

The term ACSR stands for Aluminum Conductor Steel Reinforced. In electrical engineering, this designation refers to a type of overhead power line conductor that combines the advantages of aluminum and steel. The aluminum provides excellent conductivity and is lightweight, while the steel adds strength and durability, allowing the conductor to span longer distances and withstand environmental stresses such as wind or ice loading.

The use of ACSR conductors is prevalent in the transmission and distribution of electrical energy because they effectively balance the need for high conductivity with the structural integrity required for overhead lines. This makes ACSR an optimal choice for utility companies aiming to ensure reliable power delivery while managing the mechanical challenges associated with long spans and heavy loading conditions.
