    BS 6360 cl.5 / IEC 60228 cl.5
  • Core insulation of silicone
  • 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
  • Cores stranded in layers with
    optimal lay length
  • Inner sheath of silicone
  • Tinned copper braided screen,
    approx. 85% coverage
  • Outer sheath of silicone
  • Sheath colour: preferentially redbrown
  • With meter marking
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.

    x = without GN-YE conductor
  • AWG sizes are approximate equivalent
    values. The actual cross section is in mm².
  • Unscreened analoguetype:
    SiHF
Application
Silicone-rubber-insulated cables are used for all applications where the cable insulation is subjected to high temperature fluctuations. These cables are heat-resistant for continuous use at temperatures up to +180°C, as well as for short periods of time at +220°C. Silicone-rubber-insulated cables 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.
