Approvals

Cable Construction

Circular bare copper conductor of stranded wires to DIN VDE 0295 cl. 2 and IEC 60228 cl. 2
Inner semi-conducting coating
Conductor insulation of cross-linked Polyethylene (XLPE), PE-compound DIX8 to HD 620.1
Outer extrusion of semi-conducting coating spliced with the XLPE-insulation
Conductive wrapping
Shield: Braiding of copper wires with one or two tapes applied helically
3 conductors stranded
Extruded jacket over three conductors
PVC outer jacket, compound DMV6 to HD 405.1 and HD 620/1
Jacket color: Red

Application

Suitable for indoor installation and in cable ducts, outdoors, underground and in water as well as for laying racks for industrial and switching systems and power plants. Limited use when buried in ground if the PVC outer jacket could be damaged by high mechanical stress.
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.

Properties

Self-extinguishing and flame retardant according to DIN VDE 0482 part 265-2-1 / EN 50265-2-1 / IEC 60332-1 (equivalent DIN VDE 0472 part 804 test method B)
The materials used in manufacture are cadmium-free, contain no silicone and are free from substances harmful to the wetting properties of lacquers
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

AWG sizes are approximate equivalent values. The actual cross-section is in mm².
For laying underground : For ground thermal resistance of 1 K·m/W, laying depth 0.7 m, ground temperature +20°C/68°F, EVU load grade 0.7.
For laying outdoors : Air temperature +30°C/+86°F, EVU load grade 1.0.
Conversion factors for laying in ground especially for laying in bundle form and other requirements are noted din DIN VDE 0298 part 2 and 0276 part 1000.
