Aluminum cable is a type of electrical wiring made from aluminum conductors instead of copper. Known for its lightweight properties, cost-effectiveness, and high conductivity, aluminum cable is widely used in power transmission, industrial applications, and residential wiring.



Why Choose Aluminum Cable?



  • Cost-Effective: More affordable than copper.

  • Lightweight: Easier to install and transport.

  • Corrosion-Resistant: Especially when properly treated.

  • High Conductivity: Excellent electrical performance.

  • Flexible Applications: Used in industrial, residential, and commercial sectors.







Types of Aluminum Cable


1. AAC (All Aluminum Conductor)



  • Used in low-voltage power distribution.

  • Ideal for overhead lines.


2. AAAC (All Aluminum Alloy Conductor)



  • Stronger than AAC.

  • Used in medium-voltage applications.


3. ACSR (Aluminum Conductor Steel Reinforced)



  • Steel core enhances strength.

  • Common in high-voltage power lines.


4. ACAR (Aluminum Conductor Alloy Reinforced)



  • Combines high strength and conductivity.

  • Used in transmission and distribution networks.


5. XLPE Insulated Aluminum Cable



  • Cross-linked polyethylene insulation enhances safety.

  • Used in underground power transmission.
