THERMFLEX 180 EWKF - silicone multicore cable, halogen-free

At HELUKABEL, we offer a wide range of electrical cable products. THERMFLEX 180 EWKF signal cable belongs to an outstanding line of heat-resistant cables used in many industries. The product is made of a halogen-free silicone compound with a low smoke density, ensuring the safety of all constructions.

Cable structure

  • Tinned copper conductor, to DIN VDE 0295 cl.5, fine-wire, 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
  • Outer sheath of special silicone compound type 2GM1 to DIN VDE 0207-363-2-1/DIN EN 50363-2-1
  • Sheath colour is black (RAL 9005)
  • with meter marking


  • Smoke density - low

  • 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 cables

  • Hardly any changes in dielectric strength and the insulation resistance are 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, tropical influences and

  • Weather, lake water, oxygen, ozone

THERMFLEX 180 EWKF signal cable at HELUKABEL is used in many environmental conditions, especially applications with high mechanical stress, requiring good insulation and high-temperature resistance. The product can be used in dry, wet rooms and outdoors. The halogen-free silicone cable is suitable for application in air conditioning, lighting, and electrical wiring for ovens, saunas, solariums, foundries, steel, cement, ceramic works, and other industries' heating and cooling equipment.

All silicone cables are also available in FRNC (fire-resistant non-corrosive) versions. The sheath is designed with a special compound suitable for flame test method C according to DIN VDE 0472 part 804 and IEC 60332-3 as well as HD 405.3. In addition, this compound is also capable of self-extinguishing. Therefore, THERMFLEX 180 EWKF signal cable can be installed as a security cable in crowded places such as public buildings, power stations, hotels, and airports.

The product complies with EC Low Voltage Directive 2006/95/EC.
