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.
