Definitions

  • the present invention relates to providing an improved form of power interconnection system which is ideally suited for the distribution of electricity to households, factories, etc.
  • One form of power distribution system common in Australia and elsewhere is the three phase form of power distribution which, as a fundamental component, utilises a group of at least four cables being a neutral cable and three phase cables, forming a fundamental unit of distribution.
  • the cable 1 includes an outer casing 2, normally made of plastic or polyurethane type materials and an inner core 3 which normally comprises aluminium or the like and is designed to conduct electricity and comprises a large number of small individual wires 4 closely packed together to form a combined cable.
  • the cross-sectional profile of the cable 1 is in a "tear drop" or substantially triangular form.
  • the advantage of this form is that when four cables are brought together the four cable unit can be made to have a substantially circular circumference. This is clearly illustrated in Fig. 2 which shows four cables 1, packed together inside a circular jacket 6, making an ideal form of three phase of power distribution, especially when the cable 6 is laid in an underground form.
  • the system is commonly referred to as the loop-in and loop-out system.
  • the power distribution system normally utilises a form of cable 6 to take power from the sub-station to a distribution area such as a street corner.
  • a customer to the cable 6 with the type of connection depending on the type of supply requirements of the customer.
  • three types of interconnection to standard cables 1 are common.
  • the first type is known as the "single header”.
  • the second type of connection is normally known as the "triple header" and this is normally utilised where a cable is to be branched, for example, to go down another street.
  • the third type of connection is normally called a "link panel” or “switch” and this is usually used at an open point where the cable meets between two sub-stations. Link panels are also used where isolation may be required by any point in the line and another intended use is in street light columns.
  • a link panel or “switch”
  • FIG. 3 One common existing system for connecting to the cables is illustrated in Fig. 3 and relies on the utilisation of an aluminium lug 8 having a tab 9 with through hole 10.
  • the outer casing 2 of cable 1 is stripped back exposing the inner core 3.
  • the lug 8 is designed to fit over the stripped core 3 and the sides of the lug 8 are then crimped so as to engage the inner core 3 in a permanent fit.
  • lug 8 is therefore the need to apply a high compressive force to the lug so as to physically deform the lug so as to fit to provide a permanent connection to the inner core 3.
  • the known systems interconnecting standard cables have a number of significant disadvantages especially where lugs are used.
  • the arrangement of Fig. 4 takes a substantial time to install and requires the utilisation of crimping tools in order to crimp lugs 8 onto the end of the cables.
  • a heat shrinking cover is often applied.
  • the heat shrinking has a number of undesirable features. For example, it cannot be conducted in areas where fire restrictions apply, and is found to be extremely difficult to apply on wet and windy days. Sometimes faults can occur due to cracking when the application is not well controlled.
  • the prior art type of triple header and link panel provide minimal insulation and, in the event of accidents, exposed wires can be often left with the obvious dangers to life and limb. Further, the prior art triple header and link panel arrangements are unduly bulky and require a long time to install.
  • the link panel of the prior art further involves interconnection of parts which are "live” with the obvious dangers. Further, the plastic panel cover of the prior art type of link panel can often become lose or disintegrate from heat build up.
  • an apparatus for interconnecting at least two power supply cables comprising a conductive block portion including a first through aperture and a second through aperture each of the apertures being adapted to receive a conductive end portion of one of the power supply cables; and each of the apertures further comprising a clamping means for fixing the conductive end portion firmly to a first wall portion of the aperture.
  • the clamping means can further include a first plate including a surface adapted to mate with a corresponding surface of the block portion so as to form a second wall portion of the aperture, the plate being fixed in a direction perpendicular to the supply cable; and a screw bolt mounted through a plate aperture in the first plate and adapted to engage a conductive end portion of a corresponding power supply cable, the screw bolt engaging a thread in the plate aperture so as to fix the conductive end portion to the first wall upon tightening of the screw bolt .
  • the conductive block portion can further include a distribution means comprising at least one further aperture adapted for the insertion of a rigid pole so as to provide a means for taping off power interconnections to the conductive block portion.
  • the aperture comprises an exterior lip portion of the conductive block portion.
  • the conductive block portion is ideally extruded from a single piece of conductive material as is the first plate.
  • the surface profile of the first wall portion can be shaped so as to substantially mate with the expected surface profile of the conductive end portion and the conductive block portion comprises two conductive extruded sections bolted together so as to form the conductive block portion.
  • the conductive block portion is constructed from a single extruded section.
  • the conductive end portion comprises a hollow cylindrical ferrule clamped around an end wire portion of the power supply cable.
  • the ferrule can be provided with a hollow aperture which is shaped to substantially mate with the profile of the power cable.
  • the ferrule further preferably includes a sidewall slot such that when the ferrule is compressed the ferrule mates substantially with the end of the power supply cable by means of the slides of the slot being drawn together.
  • the apparatus can further comprise a non-conductive cover formed so as to mate with the conductive block portion in a compact manner, the cover including suitably positioned apertures for the passage of the power supply cables.
  • the cover can comprise two cover portions joined together so as to encase the conductive block portion, the cover being constructed from a polycarbonate material.
  • the apparatus is ideally suited for use as a bimetal connection through the choice of material for the ferrule so as to provide for a bimetal connection between the conductive block and the power cable.
  • the power cable can be constructed substantially from aluminium and the ferrule can be constructed from tin plated copper.
  • a hollow cylindrical ferrule for clamping around an end wire portion of the power supply cable, the ferrule is provided with a hollow aperture which is shaped to substantially mate with the profile of the power cable, the ferrule further including a sidewall slot such that when the ferrule is compressed the ferrule mates substantially with the end of the power supply cable by means of the slides of the slot being drawn together.
