Definitions

  • the present invention relates to a fire-resistant security cable. More particularly, the present invention relates to a substantially flat fire-resistant cable, which comprises at least two electrical conductors which are adjacent to one another.
  • the safety cables are in particular power transmission or data transmission cables, such as for control or signaling applications.
  • the fire-resistant safety cables must, during a fire, maintain an electrical function. Preferably, said cables must also not spread the fire. Said security cables are used, for example, for emergency exit lighting and elevator installations.
  • the fire resistant cables must meet criteria set in particular by the French standard NF C 32-070. According to this standard, the cable is laid horizontally in a tubular furnace which is temperature-controlled up to 920 ° C for 50 minutes. The cable must not present a short circuit during this rise in temperature and for 15 minutes at 920 ° C. During all this time, to simulate falling objects during a fire, the cable is subjected periodically to shock by a metal bar to shake the cable.
  • the cables satisfying the test defined by NF C 32-070, paragraph 2-3 belong to category CR1.
  • Criteria similar to those defined in the French standard NF C 32-070 are also defined by international standards, such as IEC 60331, or European standards, such as EN 50200.
  • JP 01-117204 and JP 01-030106 disclose two flat fire-resistant cables, said cables comprising a plurality of conductors surrounded by an insulator and an outer sheath of polyethylene, the insulating layer of each electrical conductor being made of mica ribbons.
  • a flat fire-resistant cable which is provided with an insulating layer made of mica ribbons has several disadvantages.
  • such a cable may have a gap (or space revealing the conductor) at the level of the mica ribbon envelope, resulting in a defect in the protection of conductors leading to a short circuit.
  • Fire resistant cables having a substantially round cross section are also known.
  • the document EP 942 439 discloses a safety wire, round, fire-resistant and halogen-free, comprising at least one conductor, an insulator around each conductor and an outer sheath, voids being provided between said sheath and said insulator of each electrical conductor.
  • each conductor is made of a composition formed of a polymeric material containing at least one ceramic-forming filler and able to transform at least superficially in the ceramic state at high temperatures corresponding to fire conditions .
  • the outer sheath is made of a polyolefinic composition containing at least one charge of metal hydroxide.
  • a fire resistant cable having a round cross section has several disadvantages.
  • a fire-resistant cable having a round cross section has a high risk of pollution of the insulating layer by the ashes resulting from the combustion of the outer sheath.
  • This was due in part to the reciprocal arrangement of the isolated elements. Indeed, in the case of a cable having more than two insulated elements, at least one insulated element is superimposed on the others so as to ensure a round cross section of the cable.
  • An insulated member generally comprises an electrical conductor and an insulating layer surrounding said conductor.
  • the outer sheath is generally converted, under the action of a fire, into ashes which may hinder the transformation of the polymeric material of the ceramic insulator, resulting in cracks in the driver's insulation.
  • the superposition of the isolated elements can cause a significant increase in the size of the cracks, resulting from a crushing of (s) layer (s) insulating (s) contaminated (s) by said ash.
  • These disadvantages lead to a reduction of the insulating protection by the insulating layer (s) of the cable and to an increase in the risk of short-circuiting the conductors.
  • These risks concern, in particular, superposed isolated elements.
  • insulated electrical conductors used in round, fire-resistant safety cables are generally twisted.
  • the twisting of the isolated elements leads to the existence of multiple contact zones between said isolated elements, in particular from three elements, causing risks of short-circuiting, for example when the insulation has defects in its structure, as cracks that can be created during the ceramic transformation of the high temperature insulation on the conductors.
  • objects such as a beam or elements of a building structure
  • objects can fall and hit the cable and thus damage the cable and alter the mechanical strength of the insulation transformed into ceramic , or being transformed into ceramic, of each element.
  • the fall of such an object can lead, in the case of twisted elements, to an isolated element being compressed between said object and another element of the same cable, resulting in damage to the insulation transformed into ceramic or in the process of ceramic transformation, and thus causing a short circuit of the two conductors.
  • twisting of the cable elements generally leads to the formation of mechanical stresses which remain inside the cable and are released during a fire, which can damage the cable insulation material during its transformation. in ceramic layer.
  • a fire-resistant cable which is flat and whose insulating layer is formed from at least one polymeric material capable of being transformed at least superficially in the ceramic state to high temperatures in fires overcomes the disadvantages mentioned above.
  • the flat fire resistant cable according to the present invention overcomes the disadvantages of a round section cable and those of a cable whose insulating layer is made of mica ribbons as a barrier to fire spread.
  • halogen-free cable is meant a cable whose components are not substantially halogenated. Even more preferentially, the constituents do not comprise any halogenated compound.
  • the fire-resistant cable according to the present invention is substantially flat, that is to say it comprises at least two substantially plane faces and substantially parallel to each other, the isolated elements being adjacent between them and their axes being in the same plane which is between said at least two faces.
  • the sheath of the cable in cross section, has an outer contour (or outer profile) which substantially follows the shape of the envelope of the insulated elements which are located inside the sheath of the cable, their axes lying in the same plane.
  • the sheath of the cable preferably has a thickness which is substantially constant on the extrados of the insulated members and which can be reduced to a minimum value sufficient to provide the cable with the typical protection of a cable sheath.
  • the cable of the present invention leads to a reduction in the amount of sheath material used for making the cable, especially for the two-conductor cable. On the one hand, this reduces the manufacturing cost of the cable, and on the other hand a reduction in the incandescent time, the heat energy released during a fire and the amount of ash resulting from the combustion. of the sheath. These aspects are particularly advantageous because the risk of cracks that can be caused by the ashes during the ceramic transformation of the insulator at the high temperatures of a fire can be reduced significantly.
  • the outer surface of the sheath is larger in the present invention, which allows for better heat exchange and better and faster combustion of the sheath that will less disrupt the ceramic transformation of the insulation during the fire.
  • the particular arrangement of the insulated elements as defined in the invention also makes it possible to increase the electrical resistance of the conductors by reducing any short-circuiting of the conductors.
  • This aligned arrangement of isolated elements in the same plane i.e. the arrangement that the insulated elements are adjacent to each other and side by side
  • This aligned arrangement of isolated elements in the same plane furthermore makes it easier to manufacture the cables by eliminating them. Twisting step, and a stack of cables during installation, less cumbersome than that obtained with round cables.
  • the cable according to the present invention has, in cross-section, a substantially rectangular outer profile, and more particularly two substantially plane faces substantially parallel to the plane comprising the axes of the conductors, and two substantially rounded lateral portions which are connected to said two faces. .
  • the substantially flat fire-resistant cable of the present invention comprises a cable jacket having an outer contour which substantially conforms to the shape of the envelope of the insulated members.
  • the cable thus has a cross section of "8".
  • the material of the outer sheath preferably comprises an ethylene / vinyl alcohol copolymer (or EVA), a polysiloxane, a polyolefin such as polyethylene, polyvinyl chloride (or PVC), or a mixture thereof.

  • the material of the outer sheath may further comprise mineral fillers capable of turning into residual ash under the effect of high temperatures of a fire, such as chalk, kaolin, metal oxides such as hydrated alumina, or metal hydroxides such as magnesium hydroxide, metal oxides or hydroxides that can serve as flame retardant fillers.
  • the material of the outer sheath may optionally be expanded so as to improve in particular the impact resistance of the cable shock to which it may be subjected following the fall of an object during the fire.
  • the outer sheath may be in the form of a single layer or of several layers of polymeric material (s), for example, 2, 3 or 4 layers.
  • polymeric material for example, 2, 3 or 4 layers.
  • the insulating layer is constituted in particular from at least one polymeric material able to transform at least superficially in the ceramic state at high temperatures in the fires, especially in the interval ranging from 400 ° C to 1200 ° C. This transformation in the ceramic state of the polymeric material of the insulating layer ensures the maintenance of the physical integrity of the cable and its electrical operation in the conditions of the fire.
  • the polymeric material of the insulating layer is preferably a polysiloxane such as a cross-linked silicone rubber.
  • the insulating material may furthermore preferably comprise a forming charge ceramic under the effect of high fire temperatures, such as silica or metal oxides.
  • the polymeric material of the insulating layer may be foamed. This expansion makes it possible in particular to improve the impact resistance of the insulated conductor, shock to which it may be subjected during a fire following the fall of an object such as a beam.
  • the insulating layer may be in the form of a single layer or multiple layers of polymeric material (s), such as 2 or 3 or more layers.
