N2XSY Medium Voltage Power Cable single core 6/10 kV, 12/20 kV, 18/30 kV
XLPE Insulated, Copper conductor, singe core, screened, PVC
sheathed
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.
| 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. |
