Weight is an important factor in selection of the right  electrical material. Aluminium has been increasingly used as a substitute for copper   in power lines , as it provides application of cheaper and lighter supporting structures. Apart from this, thin strips made of aluminium are used as a protective cover for some energy cables. Aluminium’s better flexibility makes the application process easier. Aluminium’s corrosion resistance and its long-term application life are unbeatable in reducing maintenance costs. Due to its excellent properties, its field of application also includes various electrical appliances, transformers, solar collectors and other equipment.
