Medium voltage cables

CADIVI

 

General scope

- Medium Voltage Cables are used for power transmission, distribution in primary aerial cable on pole , voltage 12/20(24) kV
- Permitted long- term working temperature is 90OC
- Permitted maximum short-circuit temperature is 250OC for a period not longer than 5 seconds.
- Cable structure :
  •  Conductor : constructed from hard copper wires (or hard aluminum wires), noncompacted , concentric stranded 
  • Conductor sreen: should be an extruded layer of semi-conducting
  • The insulation should be XLPE .
  • Insulation sreen should be an extruded layer of semi-conducting .
  • Oversheath should be an extruded PVC or HDPE .
