Definitions

  • the present invention relates to a liquid-cooled electric cable for the transport of very high intensities under low voltages, comprising a tube, or other preformed pipe, not leaktight, surrounding an axial cavity for circulation of the liquid, a conductive core surrounding the tube. , a separation envelope made of a non-conductive material, an outer conductive layer coaxial with the conductive core, and a sealed outer sheath.
  • Such a cable does not avoid blockages at certain points of the annular cooling chambers, owing to the fact that its various elements are kept apart only by their fastenings at the two cable ends in sockets. It can therefore only be of reduced length, and it is nevertheless unevenly cooled as soon as it is subjected to a significant curvature.
  • the object of the present invention is to provide a liquid-cooled electrical cable which is efficiently and uniformly cooled, even if it is of appreciable length, the cooling conduits of which are not liable to be obstructed as a result of breakage or wear of certain elements, and which provides good protection for its conductors against the mechanical forces to which it is subjected in service.
  • the cable according to the invention is characterized in that the separation envelope is in contact with the conductive core and with the outer conductive layer, and in that it is perforated so as to allow the circulation of the coolant between the core and the outer conductive layer.
  • the single figure of the drawing shows by way of example, in perspective with partial cutaway, one end of a water-cooled cable according to the invention.
  • the cable comprises axially a central tube 1 provided with perforations 2 distributed regularly over its periphery and its length, and serving for the supply of coolant.
  • This tube could be replaced by a tube with circular segments fitted together without sealing, of the type used for flexible water supply tubes for shower heads.
  • the tube 1 is surrounded by a bundle 3 of straight or long-wired helical conductors 3A, formed of stranded strands, constituting the first conductive layer of the cable.
  • This conductive layer is surrounded by an openwork sheath 4 of thermoplastic or elastomeric material, formed by extrusion, and composed of helical bands 5 integral with interlaced bands 6, leaving openings 7.
  • a second conductive layer 8 also formed of wired conductors 8A.
  • This conductive layer is surrounded by a second sheath perforated extruded material 9 made of thermoplastic or elastomer, formed by extrusion, and composed of helical bands 10, integral with interlaced bands 11, leaving openings 12.
  • This extruded sheath 9 could also not be perforated.
  • the structure of the sheaths 4 and 9 is such that it allows a longitudinal circulation of the cooling water between the conductive layers and possibly around the second outer layer in contact with these two layers.
  • the two inner and outer conductive layers of the cable are respectively connected to connecting lugs 14, 15, either with the terminals of a resistance welding clamp or of an arc welding torch, or with the terminals d 'a welding station, depending on the end of the cable in question.
  • the connection of the terminal and of the sheath 13 is optionally carried out by means of a rotary joint 16.
  • thermoplastic or perforated elastomer The manufacture of sheaths in thermoplastic or perforated elastomer is carried out by separately introducing the first conductive layer or the internal cable part or the second conductive layer in the center of an extruder, and by extruding two layers on the conductive layer in question. of thermoplastic or elastomer material integral with one another, an inner layer using a punch and an outer layer using a die. This punch or this die is either fixed if one wants to obtain a layer with longitudinal strips, or rotating if one wants to obtain a layer with helical strips.
  • the electric cable which has just been described with reference to the figure of the drawing appears to be the preferable embodiment of the invention, it will be understood that various modifications can be made to it without departing from the scope of the invention, certain of its organs which can be replaced by others which would play a similar technical role.
  • the conductive layers could be formed of stranded conductors.
  • the electric cable of the invention is particularly applicable to connections between a welding station and resistance welding tongs or an arc welding torch.
