3 Core XLPE Insulated Medium Voltage Power Cable 3.6/ 6 kV, 6/ 10 kV, 8.7/ 15 kV, 12/20 kV

XLPE Insulated, Copper conductor, 3 core, screened, PVC sheathed

The 3 cores XLPE Insulated MV power cables are designed for distribution of electrical power with nominal voltage Uo/ U: 3.6/ 6 kV, 6/ 10 kV, 8.7/ 15 kV, 12/20 kV and frequency 50Hz.

This XLPE Insulated cables are widely used in the building and construction, renewable energy, and power transmission industries where the cables can be laid directly into the ground or cable ducts.

Construction of XLPE Insulated MV Cable

XLPE Insulated Medium Voltage Power Cables( Unarmoured )Copper Conductor 6-36 kV

CONSTRUCTION OF XLPE INSULATED MV CABLE:

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. FILLER

– PP filler

7. WRAPPING TAPE

8. SHEATH

– Outer sheath of PVC compound

Core identification:

– Colored tapes under screen.

XLPE INSULATED 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.
