ACSR Conductor is a high-strength, high-efficiency electrical conductor widely used in overhead power transmission and distribution. It consists of a core of galvanized steel strands surrounded by concentric layers of aluminum wires, providing a balance between conductivity, mechanical strength, and durability.
Why Choose ACSR Conductors?
- High Tensile Strength: The steel core enhances mechanical strength, making ACSR ideal for long spans and extreme weather conditions.
- Lightweight Yet Strong: The aluminum outer layers provide high electrical conductivity with reduced weight.
- Corrosion Resistance: Galvanized steel core prevents rust, extending service life.
- Cost-Effective: Affordable compared to copper conductors, offering a superior price-to-performance ratio.
- High Current Capacity: Optimized for efficient power transmission with minimal losses.
