Conductor screen: Semi-conducting material

Insulation: XLPE (Cross-Linked Polyethylene) Type GP8 to BS7655

Insulation Screen: Semi-conducting material

Metallic Screen: Individual and overall copper tape screen to BS6622

Filler: PET (Polyethylene Terephthalate) fibres

Separator: Binding tape

Bedding: PVC (Polyvinyl Chloride) Type TM1 to BS7655

Armoring:

Single Core: Aluminum Wire Armored (AWA)

MultiCore: Steel Wire Armored (SWA)

Sheath: PVC (Polyvinyl Chloride) Type TM1 to BS7655

3 Using features

1.Rated voltage: Uo/U:3.6/6kV, 6/10kV(11kV), 12/20kV(24kV), 19/33kV, 26/35kV(35kV).

2. No. of core: Single core or three cores.

3. The highest allowed operating temperature of conductor for long-term working is 90oC. In short-circuit (Max. longterm is no more than 5 seconds). The highest temperature for conductor is no more than 250ºC.

4. D.C. resistance of the conductor complies with the stipulations of 3.6/6kV, 6/10kV(11kV), 12/20kV(24kV), 19/33kV, 26/35kV(35kV).

5. The environment temperature should be no lower than 0oC when lay. Otherwise it should be preheated.

6. The cable is laid without horizontal drop limit.

7. Working Frequency Voltage Test: 3.5Uo/5min without puncture.

8. Partial Discharge Test: The discharge volume should be no more than 10pC under 1.73Uo for the cable.

9. Minimum Bending Radius

Single core – Fixed: 15 x overall diameter

3 core – Fixed: 12 x overall diameter

(Single core 12 x overall diameter and 3 core 10 x overall diameter where bands are positioned adjacent to joint or terminations provided that the bending is carefully controlled by the use of a former)

Note:

The single core armored cables are used for D.C. system only. If used for A.C. system, the magnetic isolation should be applied on the steel armor wires of non-magnetical materials should be used.
