Australian Standard (Medium Voltage)

12.7/22kV Single Core Screened & PVC Sheathed (Al Conductor)

Application

12.7/22kV Single Core Screened & PVC Sheathed (Al Conductor) cables are designed to be used for the supply of electrical energy in fixed applications up to the rated voltages at a nominal power frequency between 49Hz and 61Hz.,12.7/22kV Single Core Screened & PVC Sheathed (Al Conductor) are suitable for use in distribution installation, electrical power station , they are applied for installation, outdoors, underground where subject to mechanical damage.

Standard
