Definitions

  • the present invention relates to an electric wire according to the preamble of claim 1.
  • a wire is for example known from document DE-A-2 727 520.
  • It relates more particularly to a protective net produced from such a wire and allowing the surveillance of sensitive areas.
  • Such cables could for example be attached to a fence constituting the fence.
  • the object of the present invention is to remedy these drawbacks by proposing a particularly simple, inexpensive, unitary, flexible protection system suitable for easy installation on any site.
  • the subject of the invention is an electrically conductive wire comprising an electrically conductive core surrounded by a covering of synthetic fibers preferably constituting a braid, characterized in that it constitutes a knitted mesh net and electrically connectable to a means for any signaling of a cut in said net and in that the outer covering forming a braid can be impregnated with a layer of impermeable material which allows in particular its use under water.
  • the conductive core may consist of two wires twisted in a sheath of insulating material.
  • an electrically conductive wire according to this invention is knotted to form a net 1 comprising meshes 3 of any size and connected by nodes 2.
  • This net 1 is produced from an electrically conductive wire comprising an electrically conductive core surrounded by a covering of synthetic fibers constituting a braid 4.
  • This braid is impregnated with a layer of weatherproof and waterproof material.
  • the electrically conductive core consists of two wires twisted 5, each wire consisting of an electrically conductive metal wire in an insulating sheath.
  • net 1 produced according to the principles of this invention constitutes a unitary, flexible, relatively light assembly which can be used on any sensitive site to be protected.
  • FIG 3 there is shown the net 1, according to this invention, covering any load 9 to be protected, said net being of course anchored to the ground by any suitable means.
  • the net 1 will be connected to any means of visual and / or auditory signaling (not shown) which will be actuated during a cut or the like in the net.
  • a protective net has therefore been produced according to the invention which can be installed very easily and very quickly in any sensitive area or on any object and in any ambient environment to effectively protect this area or object.
  • the conductive core of the electric wire constituting the net could be manufactured in any way, provided that this core could of course allow the manufacture of a knotted mesh net.
