Industrial Cables Australian Standard (MV)
19/33kV Three Core Individual Screened & 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

Cable Construction

• CONDUCTOR: Plain circular compacted aluminium 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
• INSULATION: Cross Linked Polyethylene (XLPE) – standard Ethylene Propylene Rubber (EPR) – alternative
• INSULATION SCREEN: Extruded semi-conducting compound
• METALLIC SCREEN: Plain annealed copper wire: 3kA for nominal 1 second(LIGHT DUTY) Plain annealed copper wire: 10kA for nominal 1 second(HEAVY DUTY)
• SHEATH: Black 5V-90 polyvinyl chloride (PVC) – standard
• Orange 5V-90 PVC inner plus black high density polyethylene (HDPE) outer – alternative Low smoke zero halogen (LSOH) – alternative
