Medium Voltage Power Cable single core 6/10 kV, 12/20 kV, 18/30 kV to IEC 60502

XLPE Insulated, Copper conductor, singe core, screened, PVC sheathed

APPLICATIONS

The singe core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 6/10 KV to 18/30KV and frequency 50Hz. They are suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.

CABLE 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

– Annealed copper tapes 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

​

MEDIUM VOLTAGE CABLE TESTING

Routine tests: Sample tests: Type tests:
These non-destructive tests are normally carried out on all lengths manufactured.
– Conductor resistivity
– Spark test on oversheath
– Voltage tests on sheath
– D.C. voltage test on oversheath		 These potentially destructive tests are normally carried out on every production run.
– Examination of conductor and dimensions
– Hot set test for XLPE insulation
– Insulation and oversheath thickness
– Four hour voltage test		 These destructive tests are normally carried out in addition to the above tests on commencement of a particular cable supply to validate its design.
– Electrical type tests including bending and heat cycle
– Non-electrical type tests including mechanical properties after ageing and tests under fire conditions.
