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
- 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.
- AAAC CONDUCTOR has a better corrosion resistance and better strength to weight ratio and improved electrical conductivity than ACSR CONDUCTOR on equal diameter basis.
