18 / 30kV Outdoor Medium Voltage Power Cables For Power Supply Stations

STANDER

International: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

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.
