SiHF-C-Si - Silicone Shielded Double Jacket Multi-Core Cable

Product application:

SiHF-C-Si is a special 180 Degree C. silicone multi-core cable for use in high and low temperature areas or whenever the insulation is subject to extreme temperature changes. These cables are mainly found in steel producing industry and aviation industry as well as in ship building, cement, glass and ceramic factories. SIHF-C-Si cables are low-smoke and halogen-free especially suited for use in power stations. The silicone jacket provides added heat, chemical, oil and acidic resistance while the internal tinned copper braid shield protects against electromagnetic interference offering disturbance free signals and impulses. Not permitted for outdoor use

Construction:

  • Tinned copper conductor according to DIN VDE 0295 cl.5, BS 6360 cl.5 and IEC 60228 cl.5
  • Conductor insulation of silicone
  • Conductor identification according to DIN VDE 0293-308, single color, or black conductors with sequential numbering
  • imprinted in white, for 2 conductors brown, blue
  • Conductors stranded in layers with optimal lay-length
  • Green-yellow grounding (3 conductors)
  • Inner jacket of silicone
  • Braid of tinned Cu wires, coverage approx. 85%
  • Silicone-rubber-insulated common outer jacket
  • Jacket preferentially red brown color 

Technical:

  • Special silicone-insulated cable with higher heat-resistance adapted to DIN VDE 0250 part 1 and part 816
  • Temperature range: -60°C to +180°C
  • Short time temp up to +220º C
  • Temperature limit at the conductor in operation +180°C 
  • Nominal voltage: 300/500 V
  • Test voltage: 2000 V
  • Insulation resistance :min. 200 MΩ x km
  • Minimum bending radius: flexing 10 x cable Ø
  • Coupling resistance :max. 250Ω/km
  • Radiation resistance: up to 20x106 cJ/kg (up to 20 Mrad)

Properties

  • Advantages
    Hardly changes of dielectric strength and the insulation resistance also at high temperatures, high ignition or flash point, in case of fire, forms an insulating layer of SiO2
  • Resistant to
    High molecular oils, fats from vegetables and animals, alcohols, plasticizers and clophenes, diluted acids, lye and salt dissolution, oxidation substances, tropical influences and weather, lake water, oxygen and UV
  • Halogen-free
    According to DIN VDE 0482 part 267/ EN 50267-2-1/ IEC 60754-1 (equivalent DIN VDE 0472 part 815)
  • Behavior in fire
    No flame propagation
    Test 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)

For laying as a fixed installation only in open or ventilated pipe systems as well as in ducts. Otherwise the mechanical properties of the silicon are reduced by the enclosed air at temperatures exceeding 90°C.
