Aluminium foil for electrical windings

COMPAREL to copper, aluminium is far more abundant. This Is particularly true for India. The price of aluminium unlike that of copper has been quite stable for over a quarter century and for equal conductivity, the current price of aluminium is very considerably lower than that
of copper. In view of its abundance coupled with
versatile properties and relatively stable and competit-ive price, aluminium has rapidly established itself in various fields and has, in particular, replaced copper in many cases. Aluminium has firmly established itself as an electrical conductor. Today approximately 97% of high voltage transmissioncables and about 75% of distribution cables are made of aluminium. During recent years alumi-nium has also made effective inroad into the bus bar
field.
