Cable structure

• Bare copper-conductor, to

DIN VDE 0295 cl.2, multi-wire, BS 6360 cl.2, IEC 60228 cl.2

• Inner semi-conducting coating
• Core insulation of cross-linked polyethylene (XLPE), compound type DIX8 to HD 620 S2

• Outer conductive layer extruded and welded with core insulation

• Conductive taping

• Screen: Braiding of copper wires with one or two tape(s) applied helically
• Wrapping
• Outer sheath of PVC
• compound type DMV6 to HD 620 S2
• Sheath colour red

Properties

• The materials used in manufacture are cadmium-free and contain no silicone and free from substances harmful to the wetting properties of lacquers

Tests

• self-extinguishing and flame retardant acc. to DIN VDE 0482-332-1-2, DIN EN 60332-1-2, IEC 60332-1 (equivalent DIN VDE 0472 part 804 test method B)Installation notes

• To guarantee an optimum on operating reliability the extruded semi-conductive layer is spliced with the insulation for long duration. For this reason we recommend a peeling tool for installation.

Note

rm = round conductor, multi-wire Further dimensions available on request.

AWG sizes are approximate equivalent values. The actual cross-section is in mm².

Application

Suitable for installation mostly for power supply stations, in indoors and in cable ducts,outdoor with protected laying, underground and in water as well as for installation on cable trays for industries, switch-boards and power stations. Due to the good laying characteristic, this can also be laid easily in difficult line guideways. The inner conducting layer between the conductor and the XLPE insulation and the firmly bonded outer conducting layer on the XLPE insulation assures a construction free of partial discharges with high operational reliability.
