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.

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.
