Australian Standard (Medium Voltage)

3.8/6.6kV Single Core Screened & PVC Sheathed (Al Conductor)

Application

3.8/6.6kV 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., they are suitable for use in distribution installation, electrical power station , 3.8/6.6kV Single Core

Screened & PVC Sheathed (Al Conductor) cables are applied for installation, outdoors, underground where

subject to mechanical damage.
