  DIN EN 50525-2-83
• Temperature range 
  -60°C to +180°C
  (for short time +220°C)

  min. 200 MOhm x km
• Power rating 
  ambient temperature up to +145°C
  to DIN VDE 0100
  for higher temperatures valid:
  150°C – load value 100%
  155°C – load value 91%
  160°C – load value 82%
  165°C – load value 71%
  170°C – load value 58%

  fixed installation 4x cable Ø
• Radiation resistance 
  up to 20×10⁶ cJ/kg (up to 20 Mrad)

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 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
• Outer sheath of silicone
• Sheath colour: preferably redbrown
• With meter marking

Properties

• 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
• 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

• Halogen-free acc. to
  DIN VDE 0482-267 /
  DIN EN 50267-2-2 / IEC 60754-2
• Behaviour in fire
  no flame propagation 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 (OB)
• AWG sizes are approximate equivalent
  values. The actual cross section is in mm².
• Screened analogue type:
  SIHF-C-Si

Application

Silicone cables were evolved for use wherever insulation is subjected to extreme temperature changes. They are heat-resistant for permanent temperature up to +180°C, for short time operation up to +220°C. The good performance of the environmental resistant properties means that silicone cables can be used at temperatures down to -60°C. Silicone cables are halogen-free cables and are especially suited for installation in power stations. They have also found their uses in the steel producing industries, aviation industry, ship building as well as in ceramic, glass and cement factories. Due to elastical characteristic of core insulations, these are used as flexible connection cable.
