Aluminium Alloy Conductor
Aluminum Alloy Conductor is manufactured using aluminum, magnesium and silicon alloy. These alloys have high electrical conductivity and enough magnesium silicide, which ensures improved mechanical properties of Aluminum Alloy Conductor after treatment. These conductors are acknowledged not only for corrosion resistance but also for improved electrical conductivity and better strength to weight ratio. it offers very high strength in comparison to AAC conductor.
