3 CORE COPPER WIRE SCREENED ARMOURED TO AS/NZS 1972 12.7/22kV XLPE insulated, screened, GSW armoured, PVC sheathed cable. Suitable as primary supply for mines and industrial networks.
1. CONDUCTOR – Compact circular stranded copper conductor complying with BS EN 60228 Class
2. CONDUCTOR SCREEN – Extruded semi-conducting compound bonded to the insulation and applied in the same operation as the insulation.
3. INSULATION – Extruded cross-linked polyethylene (XLPE) suitable for operation at a conductor temperature of 90°C.
4. INSULATION SCREEN – Extruded semi-conducting compound applied in the same operation as the insulation. Cold strippable screens are supplied as standard but fully bonded screens may be provided if specified.
5. METALLIC SCREEN – Copper tapes applied overlapped to provide an earth fault current path.
6. BEDDING SHEATH – Extruded black polyvinyl chloride (PVC) or Low Smoke Zero Halogen (LSOH) compound is supplied as standard. Alternative materials may be provided if specified.
7. ARMOURING – Single layer of circular aluminium wires.
8. OVERSHEATH – Extruded black polyvinyl chloride (PVC) or Low Smoke Zero Halogen (LSOH) compound is supplied as standard. Alternative materials may be provided if specified e.g. medium density polyethylene (MDPE).
The XLPE-protection has excellent electrical, mechanical and warm attributes in medium voltage systems. This kind of protection is superb compound safe and furthermore impervious to cold. Because of different favorable circumstances, the XLPE-protected sort has inconceivably uprooted the conventional established paper protected sorts in numerous areas. The XLPE-protected medium voltage links are planned with longitudinally water-verification. In contrast with PVC and paper-protected links, the upsides of XLPE-protected medium voltage control links are having a low dielectric factor. The great properties of XLPE-protected links stay consistent at a long temperature extend. These links can be laid in earth, in air or in cylinders. Additional data for laying, bowing range surrounding temperatures, passable rigidity with pulling head test voltages ought to be taken in the accompanying pages. We are likewise immediate deliverer to the clients building site for transient planned.
