Definitions

  • This invention resides in a method and apparatus for producing an electric cable which includes the step of extruding a perforate or reticular synthetic resin sheath onto and in intimate contact with a continuous insulated cable.
  • This invention relates to an electric cable and to an apparatus for covering the same with a perforate or reticular, more particularly synthetic, sheath.
  • the invention can cover an electric cable, inter alia for underground lines, with a perforate or reticular sheath of an insulating substance, more particularly a synthetic substance; the cable may also have external earthing conductors, in which event the provision of such a perforate or reticulate sheath which has been extruded in intimate contact with the continuous insulating covering of the cable ensures that the earthing conductors are in intimate engagement with such cable covering, the earthing conductors making electrical contact with the ground via the perforations or apertures in the insulating sheath.
  • FIG. 1 is a section in an axial plane through an embodiment of the apparatus according to the invention.
  • FIG. 2 is a perspective and partly sectioned view of the extrusion head of the apparatus shown in FIG. 1, and
  • FIG. 3 shows a portion of an underground electric cable covered with a perforate or reticular insulating sheath in accordance with this invention.
  • the apparatus according to this invention is for covering an electric cable 1 with a perforate or reticular sheath of synthetic material.
  • the apparatus mainly comprises aguide sleeve 2 whose inner diameter is large enough for cable 1 to slide without friction and which is preferably disposed horizontally, and an annular extrusion head which has the general reference 3 and whose internal diameter is very similar to the external diameterof cable 1 and which isdisposed concentrically at one end of sleeve 2.
  • the two elements 2, 3 are rigidly interconnected by an outer casing comprising: a cylindrical part 4 which extends closely around sleeve 2, their like ends being rigidly interconnected inter alia by a nut 5 and a system of bolted flanges 6; and a lateral tube 7 whose axis is substantially perpendicular to the axis of the sleeve 2 and which, when secured by means of a flange 8 to the output of some conventional form of extruding machine, for instance, a screw extruder (not shown), serves to feed head 3 with an extrudable synthetic substance.
  • Head 3 mainly comprises two items: a stationary outer collar, comprising ice two fitted elements 9' and 9"; and an inner ring 10.
  • the two elements 9', 9" are secured to one another by screwed fasteners, as 11, and the element 9" is secured to the corresponding end of the cylindrical casing part 4, inter alia through the agency of a collar 12.
  • the collar 9', 9" is completed by an inner element 13 which forms a downwards extension of, and is rigidly secured to, sleeve 2.
  • the elements, 9', 13 of outer collar 9', 9", 13 bound the inner lateral surface 14 of such collar, the diameter of surface 14 being slightly greater than the diameter of the cable 1.
  • annular passage 15 is left between the element 13 and the elements 9, 9" of the outer collar; one end of passage 15 meets surface 14 to bound an annular extrusion orifice 16, and the other end of passage 15 communicates with the inner passage of tube 7 via a duct which is contrived in the casing associated with tube 7 and which, since it is behind the plane of FIG. 1, is shown therein merely in the form of broken lines.
  • the outermost lip of orifice 16, such lip being formed in the element 9' is formed with notches 17 (see more particularly FIG. 2) which extend towards the passage 15 and join the same near its exit 16; preferably, the notches 17 are distributed evenly around the periphery of such lip.
  • such lip and its notches 17 are contrived in a ring 18 which forms a releasable part of element 9 and which is secured to the outer ring by screwed fasteners, as 19, so that ring 18 can readily be replaced by other rings formed with differently shaped, sized and distributed notches 17.
  • the inner ring 10 comprises an end part whose outer diameter is such that ring 10 can slide without friction in contact with surface 14 of the system 9, 9", 13, the internal diameter of ring 10 being such that cable 1 can pass through without friction.
  • the central part of ring 10 is prolonged by a sleeve 20 which can slide freely inside sleeve 2, sleeve 20 emerging from the opposite end of sleeve 2 by way of sealing means 21.
  • That end of sleeve 20 which is outside sleeve 2 is coupled, inter alia by a cap nut 22, to an annular plunger 23 slidable without friction in a double-acting cylinder 24 connected to the rear end of easing 4 e.g. by rods 25.
  • a servo-valve 26 the two annular surfaces 27, 27 of plunger 23 can be actuated alternately with a pressure fluid, such as oil or compressed air, supplied from a source (not shown) through distribution passages 28 in the wall of cylinder 24.
  • cable 1 is moved, for instance, at a uniform speed, in the direction indicated by an arrow 36 through end 29 of cylinder 24, plunger 23, sleeves 20 and 2, ring 10 and the collar formed by the elements 9', 9", 13.
  • Heating sleeve 30, more particularly of the kind comprising electric resistances, are disposed around the outer collar 9, 9", 13, the cylindrical part 4 and tube 7, to maintain at the extrusion temperature the synthetic substance which the extruder screw (not shown) delivers to tube 7, then to the casing passage shown in broken line in FIG. 1 and then to the annular passage 15.
  • the two end positions of ring 10 are demarcated by the co-operation of balls, as 33, which are received in recesses 34 in sleeve 20, with the flanks of an annular groove 35 with which the internal surface of the inner tubular element 13 of the outer collar is formed.
  • the sleeve for coupling the inner ring 10 to the plunger 23 can instead of sliding inside sleeve 2, slide in an annular space between sleeve 2 and the cylindrical part 4 of the casing.
  • the various elements of the collar 9', 9", 13 can be embodied in various ways.
  • the dimensions of the meshes of the synthetic reticular sheath can be varied by changing the releasable ring 18.
  • the notches 17, instead of being contrived in the outermost lip of orifice 16, i.e., in ring 18 can be contrived in the edge of the inner ring 10, in which event the latter lip is plain.
  • This latter variant can readily be devised so that the reticular sheath extruded on to the continuous covering of the cable 1 has a uniform thickness, including the crossing places of the horizontal strands 31 with the transverse strands 32 sleeve 20; in this variant too the notches 17 can be either in the outermost lip of the annular orifice 16 or in the edge of the ring 10. Also, the axis of the apparatus need not be horizontal and can be vertical or even inclined.
  • thermoplastics are of use for the extrusion of thermoplastics
  • the embodiments can readily be adapted to extrude all other extrudable substances including thermosetting plastics, viscose, glass, metals and so on.
  • FIG. 3 shows an embodiment of an underground electric cable in accordance with the invention, mainly comprising an ordinary cable having an appropriate number of pairs of insulated conductors, the whole being completely enclosed in an insulator which forms the continuous casing or envelope of the cable 1.
  • One or more external earthing conductors 37 which are helicoidal in the embodiment shown in FIG. 3, are applied to the continuous insulating envelope of the cable 1 and clamped tightly against such envelope by an insulating reticular sheath. The same secures the outer earthing conductors to the cable 1, and through the perforations in the sheath the earthing conductors can make electrical contact with the ground in which the cable is buried.
  • FIG. 3 shows an embodiment of an underground electric cable in accordance with the invention, mainly comprising an ordinary cable having an appropriate number of pairs of insulated conductors, the whole being completely enclosed in an insulator which forms the continuous casing or envelope of the cable 1.
  • One or more external earthing conductors 37 which are helicoidal in the embodiment shown in FIG. 3,
  • the reticular sheath mainly comprises parallel longitudinal strands 31 and transverse annular strands 32 which are perpendicular to the strands 31, the strands 31, 32 being rigidly interconnected at their crossing places.
  • the insulated reticular sheath used to cover the electrical cable according to the invention and shown in FIG. 3 may have been continuously extruded on the cable 1 through the agency of one of the embodiments hereinbefore described of the apparatus according to this invention.
  • a method of extruding a sheath on a cable comprising, advancing the cable to be sheathed longitudinally, extruding circumferentially spaced, parallel strands of a synthetic material on said cable extending longitudinally thereof, intermittently interrupting extrusion of said strands and during each interruption extruding a thread of the same material circumferentially of said cable, and alternating extrusion of said strands and individual threads thereby to develop a reticular sheath on said cable having substantially rectangular meshes thereon.
  • An apparatus for sheathing an electric cable with a reticular sheath comprising, an annular extrusion head through which a cable to be sheathed is advanced longitudinally, means in said head operable to extrude longitudinally of said cable circumferentially spaced, parallel strands of a synthetic material in intimate contact with said cable while said cable is being advanced longitudinally, means operable for extruding threads of the same material integral with said strands extending circumferentially of said cable and in intimate contact therewith developing said reticular sheath on said cable, and means to operate both-mentioned means relatively toalternately extrude the strands and said circumferentially extending threads.
  • first-mentioned means and the second-mentioned means comprise two annular means movable relatively axially of said cable to one operative position defining an annular orifice for extruding said circumferentially extending threads and operable to another operative position in which said means are in radial registry for extruding said longitudinally extending strands.
  • one of said annular means comprises notches along an inner edge thereof spaced circumferentially for extruding said strands therethrough when said annular means are in said another position.
  • said means to operate said both-mentioned means comprises a double-acting reciprocably driven piston and means to supply pressure fluid to said piston.
