Definitions

  • the invention relates to an electrical line with at least one electrical Head of a temperature-resistant, in the event of fire, the function maintenance of the Line securing insulation is surrounded (EP 0 106 708 B1).
  • Such lines or cables are, for example, power lines or the Lines for message or data transmission.
  • Your leader (at least one) are insulated with a special material, through which the function maintenance of a appropriate line in case of fire for a certain period of time is ensured. Machines, apparatus and devices are used during this period is still powered and information can still be received during this time be transmitted.
  • the duration should be such that, for example, all in people in a building can be informed and the lighting in the building remains switched on until the people leave it and if necessary, have brought materials to safety.
  • the consumer Predeterminable time period is, for example, between 30 minutes and 3 hours.
  • a Insulating material used which consists of a micaband, a layer Polytetrafluorethylene (PTFE) and a glass fabric coated with PTFE.
  • the PTFE is resistant up to about 600 ° C. It crumbles to ash at higher temperatures.
  • a Correspondingly insulated cables have a high fire load that is not permissible in many cases. she develops toxic and chemically aggressive gases in the event of fire due to the fluorine (Smoke) through which metals and electrical or electronic circuits can be attacked and destroyed.
  • the invention is based, so the task described above to further train that their functional integrity with a significantly reduced fire load and without the Risk of consequential damage is ensured.
  • the fire load of this line is reduced to almost zero, since the main as Mechanical hold for the protective layer serving the turns of the multifilament thread can be carried out with very little material.
  • the material of the protective layer is also free of halogen-containing substances, so that in the event of fire none harmful to the environment Gases can arise.
  • the protective layer can also be used to apply Labels for the respective line can be used.
  • the isolated line is very easy to set up and manufacture and easy to assemble because of the Multifilament thread by simply pulling in the axial direction in any length from Head can be removed.
  • the management has because of the basically sufficient Cover made of glass multifilament thread as the only layer of insulation small Dimensions so that the material used for further layers can be reduced, if the line is combined with at least one other line in one cable.
  • the electrical line shown in Fig. 1 consists of an electrical conductor 1 and a surrounding insulation 2.
  • the conductor 1 can be a solid conductor or a To be a stranded conductor. It is preferably made of copper.
  • the insulation 2 has one Multifilament thread 3 made of glass, which is around the conductor 1 with close to each other Windings is wrapped around, so that there is a completely closed envelope 4 made of glass results.
  • the multifilament thread 3 can, for example, be between 0.4 mm and 0.8 mm lying slope (lay length).
  • One lies over the casing 4 very thin protective layer 5 made of a halogen-free, temperature-resistant Insulating material. It essentially serves to hold the windings together Multifilament thread 3, but can also be used for attaching marks become.
  • the layer thickness of the protective layer 5 is preferably between 100 ⁇ m and 300 ⁇ m.
  • the multifilament thread 3 consists of quartz glass. It E-glass or S-glass could also be used, for example. He has one large number of very thin, hair-fine glass filaments that work together are twisted. For example, there can be between 1000 and 6000 such glass filaments be twisted together in a multifilament thread 3.
  • the diameter of the In a preferred embodiment, multifilament thread 3 is between 300 ⁇ m and 600 microns.
  • the hair-fine filaments are about 6 ⁇ m to 12 ⁇ m thick.
  • Multifilament thread 3 can also be bent around very small radii without one There is a risk of damage.
  • the protective layer 5 can, for example, be made of crosslinkable, ceramized silicone exist, which is applied in a bath through which the with the cover 4th provided conductor 1 is pulled through. Excess material can be removed through a Scraper nipples are removed through which the conductor 1 after leaving the bath is pulled through.
  • the protective layer 5 can also be glued to the cover 4 ceramic material can be used, which is applied in powder form, with the shell 4th glued and can also be calibrated using a scraper. In both In embodiments, the protective layer 5 is then crosslinked. That can be in preferred embodiment by irradiation with light in the infrared range be performed.
  • the protective layer 5 can also be applied as a film to the casing 4 for example made of polyimide, polyether ether ketone (PEEK) or polyester.
  • the each film can preferably be wound overlapping on the sheath 4 of the conductor 1 become. It is on the side of the sleeve 4 with a heat supply effective adhesive coated. A final heat treatment can result in a moisture-proof bonding of the film to the cover 4 can be achieved.
  • a band 6 of mica can first be applied to the conductor 1 around which the multifilament thread 3 is wound.
  • the tape 6 can with Longitudinal overlap formed around the conductor 1 or overlapping around the same are wrapped around. It is about 0.1 mm thick.
  • the line described with reference to FIGS. 1 to 4 can also have at least one further line to be combined into a cable.
  • a cable is for example in Fig. 5 shown in cross section. It has four lines L1 to L4, which correspond the embodiments according to FIGS. 1 to 4 can be constructed.
  • the lines L1 to L4 are stranded together, preferably with alternating lay direction (SZ stranding). For example, they can be stranded as star quads, such as those used in telecommunications and Data cables are used.
  • a layer 7 can be formed over the cable core formed by the lines L1 to L4 a glass fabric tape or a glass / mica tape and an electric one above effective screen 8 may be attached.
  • the band of layer 7 can be about 100 microns thick his. In a preferred embodiment, it overlaps around the cable core wound.
  • the resulting layer 7 represents a fire-resistant layer in the Fire the insulating distance between the conductors 1 of the cable core and the Screen 8 safe.
  • a copper foil or an aluminum foil can be used as the screen 8 are formed in the longitudinally running with overlap around the cable core or can be wrapped around it overlapping.
  • the respective film can be about 75 ⁇ m thick. It can be used for moisture-proof Execution of the cable on one side with an adhesive that is effective when heat is applied be coated so that the screen 8 after heating with the insulating layer 7 bonded.
  • the screen 8 can also be used as a longitudinally welded and corrugated copper tube be executed. The valleys of the copper pipe are smooth to achieve Appropriately filled in outer surface. For example, a glass or Ceramic yarn can be used.
  • FIG Braid 9 made of stainless steel wires can be arranged.
  • galvanized steel wires or stainless steel wires can be used.
  • the wires can have a diameter between 100 ⁇ m and 300 ⁇ m.
  • the braid 9 should have an optical coverage between 80% and 97%. It does not burn and ensures good mechanical stability of the Cable, especially when it is subjected to tensile and compressive loads.
  • the braid 9 has direct contact to the screen 8, so that no potentially disturbing electrical loops may occur.
