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

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. |
