IEC 60502 1 XLPE Copper Cable Single Core XLPE Insulated Wire Medium Voltage
STANDER
International:IEC60502-2
National:GB/T 12706.1-2008
CONSTRUCTION:
1. CONDUCTOR
– Bare copper class 2 to IEC 60228, round, multiwire stranded and compact
2. CONDUCTOR SCREEN
– Inner semi-conducting coating
3. INSULATION
– Core insulation of cross-linked polyethylene (XLPE)
4. INSULATION SCREEN
– Outer conductive layer extruded and per-manently welded with the core insulation
Semi-conducting type
– Over the outer semi-conducting layer, a semiconducting tape must
be used.
5. METAL SCREEN
– copper tapes helically with a minimum thickness of 0,1 mm.
Separator
– Over the screen as well as under outer sheath, a separating layer
must be used (e. g. taping).
6. SHEATH
– Outer sheath of PVC compound
