Australian Standard (Medium Voltage)

19/33kV Single Core Screened & PVC Sheathed (Cu Conductor)

Application

19/33kV Single Core Screened & PVC Sheathed (Cu 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., 19/33kV Single Core Screened & PVC Sheathed (Cu Conductor) are suitable for use in distribution installation, electrical power station , they are applied for installation, outdoors, underground where subject to mechanical damage.

Standard

AS/NZS 1429.1
