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. |
