Special Cables • Temperature Measurement • Cable Harnessing


Silicone (Besilen®) ignition cable


The ZKBi is a voltage-stable, silicone ignition cable that is heat resistant and flexible at low temperatures. It is used at high and very unsteady ambient temperatures, e.g. in thermal and process technologies, in motor engineering, in heat system technology, and in dedusting plant and fan engineering.

Outstanding features

  • halogen-free
  • flexible at low temperatures
  • heat resistant
  • voltage-stable
