Definitions

  • the invention relates to a cable of the type mentioned in the preamble of claim 1.
  • Such cables are primarily used in fire-endangering systems with a high concentration of people and property, if in the event of a fire there is no corrosive secondary damage e.g. should arise from halogens and the function maintenance of cables is necessary for a certain time ("emergency running properties").
  • DE-OS 28 47 810 describes a flame-resistant and electrical cable of the type mentioned, the individual conductors insulated with a thermoplastic or elastomer being surrounded by an asbestos coating.
  • the inner jacket also consists of an asbestos extrusion.
  • the "emergency running properties" required by a cable in the event of a fire are usually verified by a test in accordance with IEC 331.
  • the functionality of at least three hours is required on a sample with a flame exposure of 800 ° C.
  • this functionality test only relates to the insulation behavior of the cable to be tested, but not to the electrical transmission behavior in the LF range, for example when telephoning.
  • proper electrical transmission behavior in the NF range is at least as crucial and important as adequate insulation behavior.
  • the object of the invention is to provide a halogen-free, flame-retardant cable that has "emergency running properties" in the event of fire without the use of asbestos.
  • the cable should remain fully functional for at least three hours when exposed to a flame of 800 ° C (IEC test 331).
  • the cable according to the invention should have very good transmission behavior in the NF range, even in the event of a fire.
  • the conductor coating consists of at least two different components. A peeling and pressing of mica platelets into the wire insulation and thus a deterioration in the electrical transmission behavior both in the NF range and in relation to the insulation behavior is avoided.
  • an inner jacket made of a flame-retardant polymer mixture of metal oxide hydrates and other fillers it is even possible to use conventional, non-flame-retardant wire insulation materials, which ensure better electrical transmission properties.
  • the following structure has proven to be advantageous for the noise-blocking coating of the conductors.
  • Braiding is advantageous for smaller cross sections (for example 1.5 mm 2 ), while braiding is advantageous for larger cross sections.
  • a coated glass silk tape is also possible.
  • the coating consists of a halogen-free, flame-retardant polymer. It is crucial that this coating has an oxygen index of at least 40 (preferably 50). In the functional test carried out according to IEC 331 when exposed to flame, better insulation behavior was achieved at approx. 800 ° C than with the mica / glass silk coating specified under a).
  • a flame-retardant halogen-free polymer mixture with fillers and in particular metal oxide hydrates is used for the inner jacket, which is so highly filled that the oxygen index is at least 40. Materials which have an oxygen index of 50 are preferred.
  • the reinforcement is applied over the inner jacket. It preferably consists of a steel mesh. If a non-metallic version is required, a coated or uncoated fiberglass braid is possible as a reinforcement.
  • the outer jacket is made of a polymeric, halogen-free material. This material should be oil-resistant and, if necessary, waterproof.
