  • the tightening of screw bolt 25 also forces the deformable member 20 to be deformed into the space around the conductive core 22 adjacent to the jacket of the core of the sector cable thereby providing a sealing of the exterior of the cable 2.
  • the plastic element 21 in addition to the conductive core 22 are provided with apertures which mate with the aperture 28 which can include a plastic non-conductive insert. Inserted in the aperture 28 is also an output cable for providing output from the connection arrangement 10.
  • the two extruded sections 11, 12 are first bolted around a requisite position in the cable.
  • the orientation of the extruded sections 11, 12 is preferably determined beforehand so as to align the orientation of the arrangement 10 with the underlying sector cable.
  • each sector cable can be determined through the utilization of a separate clamping tool which can comprise two semi circular extruded portions which are clamped together and include a raised edge which is clamped around and cuts into a minor amount the surface of the cable.
  • the degree of cutting will be somewhat proportional to the degree of bulge such that four marks will be left of the surface of the cable when the clamping arrangement is removed with the marks indicating the position of the bulges for alignment for utilizing the arrangement 10. It is an envisaged that more accurate positioning can be readily provided through the utilization of an indicator on the outside surface of the cable 2.
  • a series of minute serrations can be placed along the surface of the cable when manufacturing the cable with the serrations being provided as an indicator of the position of the underlying sector cable.
  • the serrations eg. 30 can be spatially coded for instant visual recognition.

  • the size of the cutting end portion 36 is dimensioned so that a small circular hole is formed which neatly mates with the end of the element 21 so as to form a tight seal.
  • the tool elements 33, 34 are removed and the arrangement 19 of Fig. 3 is inserted so as to provide for the conductive tapping off an electrical interconnect.

  • the polyurethane material can be pumped inside the casing before setting so to fully encase the arrangement 10 in a further waterproof protective element.
  • a silicone grease or other silicone material could be utilized but this would be non-optimal.
  • the outer casing 44, 45 is also preferably profiled so as to allow for the dragging of the cable 2 along surface without substantial opportunities for "catching" of the external surface of the portions 44, 45 with objects. This helps facilitate the movement of cable 2 when inserted in an underground trench or the like.
  • the first illustrated embodiment therefore has a number of advantages over the prior art.
  • the embodiment allows for more convenient access for the testing or the working of the cable interconnection 2 or for testing of the cable state itself. It can further be operated in a live manner through the utilisation of appropriate non-conductive elements. Further, the current load can be more substantial than when utilising a piercing connector as the interconnection is not affected as much over time by creep and further a non-point contact is provided. Hence, heavier duty loads can be safely interconnected to the cable 2 which provides for a more economical power distribution system.

  • a rubber ring or O-ring 70 is provided for sealing the post 65 in the hole 66.
  • the post 65 is urged against the cable core by means of T-section unit 71, screw bolt 73 and resiliently compressible plug 72.
  • the hole 66 can be formed in a similar manner to that shown in Fig. 5 with the operation slightly modified as illustrated in Fig. 10 with the arrangement of Fig. 10 providing for the formation of a slightly larger hole.
  • Fig. 7 can be utilized to form up to four ⁇ tap off cables as illustrated in Fig. 11.
  • the four cables 80-83 each can provide 3 single (and neutral) outlets or a full 3 phase outlet with the connector blocks 85-87 preferably being colour coded to match the colour coding of the phase cables and the color coding of the sector cables within cable 2.
