Overhead Bare Conductor ACSR Steel Reinforced Aluminum AAC AAAC Conductor

Overhead Bare Conductor ACSR Steel Reinforced Aluminum AAC AAAC Conductor

Application

Bare conductors are extensively used for overhead distribution and transmission lines adjacent to ocean coastlines where there can be a problem of corrosion in the steel of an ACSR construction.

The inductive effect of the ACSR's steel core is eliminated, hence increasing the operating efficiency of the line.

Brief Description

1. This conductor is made from aluminium-magnesium silicon alloy of high electrical conductivity containing enough magnesium silicide to give it better mechanical properties after treatment. These conductors are generally made out of aluminium alloy 6201.
2. AAAC CONDUCTOR has a better corrosion resistance and better strength to weight ratio and improved electrical conductivity than ACSR CONDUCTOR on equal diameter basis.
