Definitions

  • the invention refers to an electrical conductor with low skin effect, designed for installations, machines, equipment and electrical apparatus with the means of which there is carried out the transport, the distribution and the use of electric power.
  • This invention eliminates the above mentioned disadvantage in such way that, in order to reduce the skin effect, is made a division of the section of the conductor by manufacturing it from several thin metal wires, each of them being covered on the outside by an electroinsulating film, thus reducing the skin effect both due to the current flow through conducting wires with a reduced section and to the repression of the current towards the center of the sections of the wires.
  • These wires are also surrounded by other wires as a result of the proximity effect that comes forth among them and through them flows current in the same direction due to the fact that they are parallel connected.
  • the electrical power conductor with low skin effect has the advantage that, by using it, there is a significant gowth of the power that is carried in a section unit of the conductor and thus significantly reducing investment costs in transport, distribution and use of electric power.
  • the conductor is made up of several thin metal wires 1 (copper, aluminium, steel), and has the role to conduct electric power with only low skin effect as a result of the small section of the wires used, each of them being coated with an insulating film 2, whose role it is to separate in a galvanic way the conducting wires and an exterior insulating coat 3 that has the role of a common insulation of conductors
  • this conductor may be manufactured without any exterior insulating coating of the twisted wires, e g for windings and for ae ⁇ al electric lines
  • the electroinsulating film that covers each of the metal wires that make up the electrical conductor shall be as thin as technologically possible and shall be made of enamel coatings, metal oxides or other electroinsulating materials that can be used in forming films and that are able to create a galvanic separation, according to the requirements of the future use of each category of conductors
  • the diameter of metal wires will, too, be as small as possible and shall be chosen according to the range in specific conditions that are required by standard norms for each category of conductors
  • the insulating coat of the metal wires When coming into use (in panels, derivations, at the poles of machines and apparatus) the insulating coat of the metal wires will be removed either by scrubbing or chemically thus making the parallel link of wires of each electric: conductor.
  • the electrical power conductor shown in this invention is to be manufactured by technologies known in the art and in use for coating wires with insulating films (enamel coatings, oxides), as well as with exterior coatings (PVC. rubber, polyethylene) and for wrapping conductor wires on machinery already used in manufacturing multiple wire conductors
  • This kind of conductor can be used with AC at low frequency and CC both al low or high tension

Abstract

Conducteur électrique à faible effet pelliculaire trouvant application dans le transport, la distribution et l'exploitation de l'énergie électrique. En vu d'une réduction de l'effet pelliculaire, le conducteur est composé de plusieurs fils métalliques minces (1) dont chacun est enrobé d'une feuille d'isolation électrique (2) assurant une réduction sensible de l'effet pelliculaire car le courant traverse des sections plus petites, ainsi qu'une réduction dudit effet dans les fils entourés d'autres fils due à une limitation du courant allant vers le centre des sections de fil en raison de l'effet de proximité qui se développe entre eux, les fils d'un même conducteur étant parcourus dans un seul sens par les courants car ils sont raccordés en parallèle.
