35KV Medium Voltage Wire MV Cable Crosslinked Polyethylene Outer Sheath
MEDIUM VOLTAGE CABLE STANDARD
According to GB12706( Equal to IEC60502). The mv cable also could be producted by standard of ASTM, BS, DIN and AS/NZS or other standards as request.
MEDIUM VOLTAGE CABLE VOLTAGE
3.6/6KV, 6/10KV, 8.7/15KV, 12/20KV, 18/20KV, 21/35KV, 26/35KV
MEDIUM VOLTAGE CABLE CONSTRUCTION
1. Conductor: Copper or aluminium (class1 or class 2)
2. Inner semi-conducting layer
3. Insulation: Cross inked polyethylene (XLPE)
4. Outer semi-conducting layer
5. Armoured or Unarmoured
6. Wrapping of conductive material
7. Screen: Braiding of copper wires or copper tape
8. Separator
9. Outer jacket: PVC or PE
MEDIUM VOLTAGE CABLE APPLICATION
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel, in cable trench, or direct in ground, able to bear external mechanical force, but unable to bear large pulling force.
MEDIUM VOLTAGE CABLE CHARACTERISTICS
1. Max Long-time operating temperature of XLPE insulated cable is 90°C
2. Installing temperature of cable should not be less than 0°C
3. Max short-circuit temperature is not exceed 250°C,Not more than5 Sec.
4. Unable be laid without the limit of fall with enough mechanical pull,Single core cable can not be laid in iron tube or fixed by circled iron tools around cables
