Cable structure
  • Tinned copper conductor, fine wire
    acc. to DIN VDE 0295 cl.5 /
    BS 6360 cl.5 / IEC 60228 cl.5
  • Core insulation of special silicone
    compound type EI2 to
    DIN VDE 0207-363-1 / DIN EN 50363-1
  • Core identification to DIN VDE 0293-308
    - up to 5 cores coloured
    - from 6 cores, black with continuous
      white numbering
  • GN-YE conductor, 3 cores and above
    in the outer layer
  • Cores stranded in layers with
    optimal lay length
  • Inner sheath of special silicone
  • Tinned copper braided screen,
    approx. 85% coverage
  • Outer sheath of special silicone
    compound type 2GM1 to
    DIN VDE 0207-363-2-1/DIN EN 50363-2-1
  • Sheath colour: black (RAL 9005)
  • With meter marking
  • Low smoke density
  • Due to the special abrasive and notch
    resistance outer sheath, these cables are
    suitable for heavy loading of mechanical
    stresses than the usual standard silicone
  • Advantages
    hardly changes of dielectric strength
    and the insulation resistance also at
    high temperatures, high ignition or
    flash point, leave in case of fire an
    insulating layer of SiO2 thereby
    ensuring a longer functional integrity
  • 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
  • G = with GN-YE conductor
    x = without GN-YE conductor
  • EWKF = Improved values to E=tearing
    resistance, W=breaking strength propagation,
    K=notch strength, F=flexibility
  • AWG sizes are approximate equivalent
    values. The actual cross section is in mm².
  • Unscreened analogue type:
These cables are ideal for use everywhere, where increased mechanical stresses for the installation and operation are required. Silicone-rubber-insulated cables are used for all applications where the cable insulation is subjected to high temperature fluctuations. For use in dry, damp and wet rooms as well outdoor. As flexible connecting cable for low mechanical stress i. e. sauna, solar installations, foundries and steel plants. This cable can be used for fixed installation only in open and ventilated cable tubes and cable ducts. An interference-free transmission of signals and pulse is assured by the high screening density.
EMC = Electromagnetic compatibility
To optimize the EMC features we recommend a large round contact of the copper braiding on both ends.
FRNC = Flame Retardant Non Corrosive
All silicone cables are available also in FRNC versions. The sheath designed with special-compound conform flame test method C to DIN VDE 0472-804 and IEC 60332-3 as well as HD 405.3. This special compound is self-extinguishing. Because of that these cables can be installed as security cable with functionality as for example in communal buildings, power stations, hotels, airports etc.
CE = Product conforms with Low-Voltage Directive 2014/35/EU.
