When it comes to overhead power transmission, one term you’ll frequently encounter is ACSR cable. But what is ACSR cable, and why is it so widely used in power distribution systems around the world?
In this article, we’ll answer that question in detail and explore the structure, advantages, applications, and specifications of ACSR conductors.
What is ACSR Cable?
ACSR stands for Aluminum Conductor Steel Reinforced. It is a high-capacity, high-strength stranded conductor used in overhead power lines. The conductor consists of a central core of steel strands, which provides mechanical strength, surrounded by one or more layers of hard-drawn aluminum strands, which carry the electrical current.

This combination makes ACSR cable an ideal choice for long-distance, high-voltage power transmission lines, particularly where high tensile strength is required.

Construction of ACSR Cable
A typical ACSR cable has:
-
Steel core: For tensile strength and mechanical support.
-
Aluminum strands: For electrical conductivity.
-
Optional galvanization: The steel core may be galvanized to protect against corrosion.
The ratio of aluminum to steel can vary based on the application—for example, ACSR Dog, ACSR Moose, and ACSR Rabbit are common types named by code, each having different strand combinations and sizes.
