Electrical Conductivity: Aluminum Rods for Power Transmission

Aluminum is widely used in the electrical industry due to its excellent conductivity, low density, and cost-effectiveness. At Chalco, we manufacture high conductivity aluminum rods specifically tailored for power transmission, overhead lines, and transformer windings. Our electrical aluminum rods are trusted worldwide for their superior performance in harsh environments.

Why Aluminum for Electrical Applications?

Compared to copper, aluminum offers significant advantages in electrical systems:

• High electrical conductivity: ~61% IACS (for 1350 alloy)
• Lightweight: ~30% the weight of copper
• Cost-effective: Lower cost per unit of conductivity
• Corrosion resistance: Suitable for outdoor and coastal environments
