Australian Standard (Medium Voltage)
6.35/11kV Three Core Individual Screened & PVC/SWA/PVC Sheathed (Al Conductor)
Application
6.35/11kV Three Core Individual Screened & PVC/SWA/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.,6.35/11kV Three Core Individual Screened & PVC/SWA/PVC Sheathed (Al
Conductor) cables are suitable for use in distribution installation, electrical power station , they are applied for
installation, outdoors, underground where subject to mechanical damage.
