Medium voltage COPPER? power cable 22KV?

?

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.
