Properties

Resistant to
high molecular oils, fats from vegetables
and animals, alcohols, plasticizers and
clophenes, diluted acids, lyes and salt
dissolution, oxidation substances,
atmospheric influences, lake water,
oxygen, ozone
For laying as a fixed installation only in
open or ventilated pipe systems as well
as in ducts. Otherwise the mechanical
properties of the silicone are reduced
by the enclosed air at temperatures
exceeding 90°C.

Tests

DIN VDE 0482-267 /
DIN EN 50267-2-2 / IEC 60754-2
Flame retardant acc. to
DIN VDE 0482-332-1-2 /
DIN EN 60332-1-2 / IEC 60332-1-2

Note

G = with GN-YE conductor
x = without GN-YE conductor
The conductor is metrically constructed
(mm²). The AWG designation is

Application

Silicone-rubber-insulated cables are used for all applications where the cable insulation is subjected to high temperature fluctuations. Can also be used at low temperatures down to -60°C because of the excellent weathering resistance of the material. These cables are halogen-free and hence are particularly suitable for applications in iron and steel works, rolling mills, foundries, in aircraft construction and ship building, as well as in cement, glass and ceramic plants. Silicone-rubber-insulated cables have demonstrated proven applications in projector and high-power lighting fixtures as well as all types of heating equipment. An interference-free transmission of signals and pulse is assured by the high screening density. The ideal interference-protected silicone multicore flexible cable for such applications as given above.
EMC = Electromagnetic compatibility
To optimize the EMC features we recommend a large round contact of the copper braiding on both ends.
CE = Product conforms with Low-Voltage Directive 2014/35/EU.
