STANDERInternational:IEC60502-2 National:GB/T 12706.1-2008 | 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 – copper tapes helically 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 *Core identification: colored tapes under screen. |

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. |
