ABC Cable, or Aerial Bundled Cable, is a type of overhead power line that uses multiple insulated conductors bundled tightly together. Unlike bare conductor systems, ABC cables are insulated, making them safer, more durable, and easier to install in urban and rural settings.

These cables are widely used in distribution networks due to their resistance to short circuits, weather conditions, and unauthorized tampering.

???? Factors to Consider When Choosing ABC Cables

1. Voltage Requirement

Ensure the cable is rated for the voltage class of your distribution system.

2. Conductor Material

• Aluminum is standard for cost-effectiveness.

• Aluminum alloy adds strength but at a slightly higher price.

3. Climate Conditions

Use XLPE-insulated ABC cables for high UV and heat resistance in tropical regions.

4. Span Length and Pole Distance

Longer spans may require messenger wires with higher tensile strength.
