Industrial Cables Australian Standard (MV)
12.7/22kV Three Core Individual Screened & PVC PVC/SWA/PVC Sheathed (Al Conductor)
Application
These 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 , they are applied for installation, outdoors, underground where subject to mechanical damage.
Standard
AS/NZS 1429.1
