Definitions

  • the present invention relates to a distributing bus-bar, particularly for electric power distribution, comprising a plurality of insulated electric conductors and a through-going carrying line.
  • the jacket is tube shaped and houses electric conductors.
  • the characterizing feature of this known hanging cable is that the electric conductors are movable with respect to each other and with respect to the jacket which permits the conductors to be axially moved with respect to the carrying line.
  • the tube shaped jacket may be made from conducting material, such as metal, or from insulating material, e.g. a thermoplastic material such as nylon or the like.
  • the carrying line is preferably embedded in the wall of the tube which may be thin-walled around the rest of its periphery.
  • this hanging cable may be designed for 1-phase or 3-phase power distribution, or for communication, signalling or control over the desired number of conductors. If not only the insulated electric conductors are introduced into the tube during the manu- facture but also one or more pulling wires the advantage is achieved that an already finished installation may be completed by one or more conductor parts. If desired it is also possible to replace electric conductors by others in an already finished installation. Further, the follow- ing advantages are gained:
  • Both the carrying line and the electric conductors can, by taking up openings in the tube shaped jacket, easily be made accessible for attachement to poles and for connection to service lines or branch lines. If the electric conductors of e.g. power distri ⁇ bution lines are parallel disposed individually insulated conductors, i.e. without a uniting winding, stranding the like, the conductors may very easily be separated to permit mounting of connecting clamps. If the tube is made from insulating material it affords a protection against disturbances if cables for different purposes come into contact with each other. A hanging cable of standard dimensions may be used for varying numbers of electric conductors and also for several conductor dimensions which facilitates the store holding.
  • hanging cables of the above described type have a plurality of advantageous properties and accordingly they have come to a widespread use.
  • the present invention has aimed at providing a distri ⁇ buting bus-bar which has at least some of the advantageous properties that are inherent with the just described hanging cable and which beyond those has some installation technical and economical advantages.
  • a distributing bus-bar comprising a carrying line and electric conductor parts which distri- buting bus-bar is characterized in that the carrying line and the conductor parts are disposed in a common electric ⁇ ally insulated jacket and that the conduction capacity of the carrying line is adapted to and is preferably the same as the conduction capacity of each one of the conductor parts so that the carrying line may be used as a comple ⁇ mentary conductor part.
  • both the electric conductor parts and the complementary conductor part consist of few-threaded aluminum conductors, e.g. of the kind which is commers- ially available under the Trade Mark “Ductalex”, but also solid • conductors may be used.
  • FIG. 1 is a perspective view of a portion of a distri- buting bux-bar according to the invention
  • FIG. 2 shows a cross-section of the distributing bus-bar.
  • the embodiment of the hanging cable shown as an example in the drawing comprises a carrying line 10 and a plurality of electric conductor parts 11,12,13,14 and 15, which are disposed in a common electrically insulating jacket 16.
  • the jacket portion 16A which surrounds the carrying line 10 and the jacket portion 16B which sur- 5 rounds the electrical conductor parts 11-15 are separated from each other by means of a web 16C so that there is a good possibility to affix the distributing bus-bar in case this is to be used e.g. as a hanging cable.
  • the carrying line 10 and each one of the 10 conductor parts 11-15 has its own insulation, so as ⁇ is indicated e.g. by the insulation 10A, 13A and 15A.
  • Each one of the conductor parts may have a conductor area of e.g. 25 mm 2 and may consist of a 7-threaded aluminum alloy, e.g. of the kind which is sold under the 15 Trade Mark "Ductalex".
  • the conductor part insulation 13A, 15A may consist of PVC and have a thickness of 1,3 mm.
  • the carrying line may similarly consist of a 7-threaded
  • the jacket 16 consists of PVC and has a thickness of 1,2 mm.
  • the conductor parts are preferably* color marked so they are easy to identify, e.g. one part green/yellow, one part blue, one part brown and remaining parts black with 25 one of the black parts also marked with the figure 1.
  • the carrying line 10, which is useful as a complementary conductor, is preferably marked green/yellow.
  • the distributing bus-bar according to the invention is with special advantages for illuminating systems within 30 industries, department stores, athletic halls, excersise tracks and underground rooms. It is also very useful in the power distribution technique, e.g. within small factories, farm service houses, work shop hotels and

Abstract

Une barre ou câble omnibus de distribution d'énergie électrique comprend un câble porteur (10) et des parties conductrices d'électricité (11-15). Le câble porteur (10) et les parties conductrices (11-15) sont disposés dans une enveloppe isolante commune (16), et la capacité de conduction électrique du câble porteur (10) est adaptée à celle de chacune des parties conductrices, et de préférence égale à celle-ci, de sorte que le câble porteur (10) peut être utilisé comme un conducteur complémentaire.
