Fire properties of coaxial cables

Many coaxial cables are designed to withstand high temperatures of up to 200°C without damage. These usually have a dielectric made of PTFE and an outer sheath made of FEB, PFA or PTFE. Cables with a dielectric and sheath made of Kapton are even temperature-resistant up to 250°C.

Please note: If temperature-resistant cables are assembled with the matching connectors and bend protectors, the maximum temperature is always that of the component with the lowest temperature resistance. If the coaxial cable is suitable for temperatures up to 200°C, but the connectors are only suitable for temperatures up to 100°C, the maximum temperature for the entire assembly is 100°C. If the maximum temperature is exceeded, the cable must be assembled properly. If this is exceeded, proper functioning is no longer guaranteed.

Many of our cables have standardised fire properties according to IEC60332-3 or DIN VDE 0472-804. As a rule, the basic requirement for this is that the cables do not contain halogens, whose fire properties would be very unfavourable. When substances such as chlorine or bromine burn, toxic substances are produced and a lot of smoke is emitted, which is why they are banned in many areas of application. Cable sheaths made of PVC contain halogens and are therefore not suitable for these areas. Their advantage, on the other hand, is the cheaper price compared to other materials.

In our range, many halogen-free cables are provided with a manufacturer-specific additive. Examples are LSNH (Low Smoke No Halogen), LSZH (Low Smoke Zero Halogen) or FRNC.
