China Good Quality XLPE Metallic Shielded 33KV Power Cable
XLPE metallic shielded 33KV power cable
1). Standard: IEC60502; GB12706.1-2002
2) Specification: Circular Copper conductor for single core and shaped conductors for muti-core, XLPE insulated, PVC bedding, armored(or unarmored) PVC sheathed cable.
Detailed description or construction:
* Conductor: compacted or uncompacted copper or aluminium
* Insulation: Cross-linked polyethylene (XLPE) or Polyvinyl chloride (PVC)
* Filler: Polypropylene filament with lapped binding tape
* Binder: Binding tape
* Inner sheath: Polyvinyl chloride (PVC)
* Armour: Galvanized steel wire armored (SWA) or steel tape armored (STA)
*Sheath: Polyvinyl chloride (PVC)
3). The rated voltages U0/U(Um) of the cables considered in this standard are as follows:
U0/U(Um) =3.6/6(7.2)-6/10(12)-8.7/15(17.5)-12/20(24)-18/30(36)-21/35(40.5)KV
In the voltage designation of cables U0/U(Um):
* U0 is the rated power frequency voltage between conductor and earth or metallic screen for which the cable is designed;
* U is the rated power frequency voltage between conductors for which the cable is designed;
* Um is the maximum value of the "highest system voltage" for which the equipment maybe used
4) Voltage:0.6/1kv,6/6kv,6/10kv,8.7/15kv,12/20kv,18/30kv,19/33kv,26/35kv
5). Application:used in ducts, trays and direct burial in ground. the cable is subjuct to immerse in water all the time.
