What does ACSR stand for?

ACSR stands for Aluminium-conducting steel-reinforced. This type of conductor consists of a central core of steel strands that provide strength and support, while the outer layer is made of aluminum strands, which are lightweight and have good conductivity. The combination of aluminum's lightweight properties and steel's tensile strength allows ACSR conductors to span longer distances in overhead power lines without excessive sagging.

The use of aluminum for electrical conductivity reduces the weight compared to copper, while the steel reinforcement contributes to the structural integrity, making it ideal for high-voltage transmission lines. This design helps manage the physical stresses encountered in overhead installations, thereby ensuring reliability and efficiency in power transmission.
