Product Introduction

Application

AAAC-Aluminum Alloy Overhead Bare Conductor is mainly used as bare overhead transmission cable and as primary and secondary distribution cable. It is also suitable for laying across basins, rivers and valleys where special geographical teatures exist.

Construction

AAAC Aluminum Alloy Overhead Bare Conductor cable consists of aluminum alloy wires concentrically stranded.

Advantage:

1. Corrosion Resistance: AAAC exhibits excellent corrosion resistance specially in sea coast areas and in polluted industrial areas due to absence of steel core.

2. Lower Power losses: Since AAAC is homogeneous (with all strands of Aluminium Alloy) with no steel component the resistance of AAAC is lower as compared to ACSR.

3. Higher Ampacity: AAAC can carry atleast 15-20% extra current as compared to ACSR of equal size

Longer Life: Experience in foreign countries shows that All Aluminium Alloy Conductors are in service for over 60 years, which is about double the life of ACSR Conductors.
