Definitions

  • the invention relates more particularly to behavior of electrical cables in the presence of fire to limit their destruction.
  • the oldest structures of the cables of safety included mineral insulating sleeves or composed of textile ribbons based on mica and / or glass fibers, constituting barriers of fire resistance around electrical conductors, requiring one or more additional steps relatively long and expensive manufacturing.
  • the objective of the invention is to provide a safety electric cable having resistance to the spread of the fire and continuity while improving its cost of manufacturing compared to previous cables.
  • polyethylene PE polypropylene
  • PP polypropylene
  • EPR ethylene / propylene / rubber
  • EPDM ethylene / propylene / diene / monomer
  • EVA poly (ethylene / vinyl acetate)
  • EBA poly (ethylene / butyl acrylate)
  • EBA poly (ethylene / ethyl acrylate EEA.
  • the material of the insulating sheath 12 also contains one or more fillers, at least part of which is ceramizable, and thus has the capacity to give rise to a gangue having a certain mechanical resistance under the effect of the high temperatures of a fire.
  • the packing mass 2 is solid without halogen and is essentially olefinic. It preferably consists of a polyolefin or an olefinic type copolymer. Examples of polymers which can be used are for example PE, EVA or EPR.
  • the packing mass 2 contains numerous anhydrous fillers. Typically, the packing mass contains relatively 50% to 80% by weight of fillers anhydrous.
  • Anhydrous fillers are for example made up of one of the following components: chalk, kaolin, talc, dolomite, silica, magnesia, alumina, calcium sulfate.
  • the material of the mass of jam 2 contains a coupling agent, such that alkoxysilane, possibly directly linked to olefinic polymer essentially constituting the packing mass, ensuring cohesion between the fillers and the polymer.
  • a coupling agent such that alkoxysilane, possibly directly linked to olefinic polymer essentially constituting the packing mass, ensuring cohesion between the fillers and the polymer.
  • this is preferably thermoplastic which does not require crosslinking; in fact, the crosslinking of the sheath requires costly, time-consuming operations several hours or even several days, such than steaming or electronic bombardment.
  • each insulating sheath 12 gives a additional benefit to the invention which is the reduction of the thickness of the insulating sheath 12. From in addition, a high charge rate and by therefore a low calorific value of the packing material results in reduction the thickness of the protective sheath 3.
  • the gain in quantity of materials used for the sheath insulating 12 and the protective sheath 3 reduces the cost of the cable, as well as the release of smoke and toxic gases.
  • the specificity of the SZ manufacturing process requires to put immediately after wiring the protective sheath 3 which maintains the assembly of insulated conductors in the agreed position.
  • the SZ assembly which has alternating twist directions of the conductors insulated, i.e. a section of insulated conductors with direct propeller pitch, then a section of insulated conductors with retrograde helix pitches and so on, remove the intermediate step hand consuming conductor assembly of work in the cable manufacturing process.
  • the extrusion of the packing mass 2 and the external protective sheath 3 is made on insulated conductors 1 grouped in the form of a classic helical assembly according to a single helical direction.
  • an electrical safety cable CA1 is armored by covering the cable CA in FIG. 1 with a metal frame 4 extending around the sheath 3 along a helix or several parallel or crossed helices , as shown in FIG. 3, either of a corrugated reinforcement with transverse-circular, or longitudinal undulations, or alternatively helical, and of a final flame-retardant sheath 5 surrounding the helical or corrugated reinforcement 4.
  • each of the isolated conductors of the cable sample is energized electrical test which depends on the nominal voltage cable typically within a range of 100/170, 100/300, 300/500, 450/750 or 600/1000 V.
  • test N ° 3 of standard NF C 32-070 is carried out on four samples of the CAa cable with the composition described above, short-circuits appear after the following durations: CAa cable test 1 test 2 test 3 test 4 11a in Cu and 12a in silicone; 3a silicone 90 mins 65 mins 90 mins 70 mins
  • the cable CA according to the invention shown in FIG. 2, or in the Figure 3 exhibits a marked fire behavior better than that of the known cable CAa shown in the figure 1.
  • the composition of the packing mass 2 therefore constitutes a determining parameter for improve the fire resistance of safety cables.
  • This fire propagation evaluation test consists in testing samples of the cable according to the invention consisting of one or more sections of length at least equal to 1600 mm under the effect of heat in a vertical test oven. ventilated environment.
  • the test is carried out in a glazed cabin which has two registers at its lower part, the operation of which makes it possible to vary the speed of flow of the ventilation air.
  • the cabin is ventilated by means of an extractor mounted at the top of the cabin and whose air flow speed through the oven when the ventilation is running, must be equal to 120 m / min ⁇ 10 m / min.
