Australian Standard (Medium Voltage)

3.8/6.6kV Three Core Individual Screened & PVC Sheathed (Cu Conductor)

Application

3.8/6.6kV Three Core Individual 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.,3.8/6.6kV Three Core Individual Screened & PVC Sheathed (Cu Conductor) cables 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

Cable Construction

CONDUCTOR: Plain circular compacted copper to AS/NZS1125 Maximum Continuous Operating Temperature: 90°C

CONDUCTOR SCREEN: Extruded semi-conducting compound, bonded to the insulation and applied in the same operation as the insulation
