Applications |
Copper-screened installation cables
for industrial electronics are used
for telecommunications and information
processing systems in environments
susceptible to interference, and for
higher requirements on the transmission
characteristics of signals and measurement
values in process control systems.
These cables are suitable for installation
in dry and moist operating areas in
buildings, above and beneath plaster
as well as for permanent outdoor and
wall installation on outer building
walls.
In accordance with new environmental
regulations, these cables are used
for control systems in fumes gas desulphurisation
units in incinerators as well as for
upgrading older installations of power
supply companies.
The overall braid screen of copper
wires provides from external electrical
interference and electromagnetic effects,
and ensures a perfect data transmission.
The use of installation cables for
power cable applications or for underground
installation is not permitted.
Characteristic features
Suitable for Termi-Point wiring due to the 7-strand wire construction.
Installation notes
• These cables shall be
reeled off from the coil or drum
without causing any twisting or buckling.
• The
bending radius for bending once without
tensile force or for multiple bending
with tensile forces shall not be
less than the given minimum bending
radius.
• The requirements
given in DIN VDE 0800 for crossings
and the proximity of systems and
stations shall be observed.
• In
accordance with the regulations of
VDE 0800 part 1, telecommunication
circuits and power circuits must
be separated from each other by adequate
insulation.

Core identification
The cores are identified by the basic
colours of the insulation which are
repeated in each bundle in the same
sequence.

The
bundles are identified by the colours
of the rings on the core insulation
and the arrangement of the colour coded
rings in groups. The groups of rings
are approx. 60 mm. Apart.
For cables with more than 12 bundles,
bundles no. 13 and onwards are assigned
coloured spirals
Method of counting
The bundles are counted from the centre
outwards.
