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.
