Aluminium Overhead Insulated Cable(High Voltage)

Aluminium Overhead Insulated Cable(High Voltage)
Aluminium overhead insulated cable(high voltage) is the cable that be set at a certain height from the tower for transmitting electric energy. It is used primarily for overhead and distribution lines. There are two main types of it: all aluminum and steel core. The steel core increases breaking force.
