Definitions

  • the present invention relates to power cables of the mass- impregnated type, i.e. metal sheathed cables insulated with paper which is impregnated with a viscous compound (also called Solid Type Paper Insulated Cables)
  • the invention is especially related to such cables designed for high voltage direct current (HVDC) transmission, underground as well as submarine.
  • HVDC high voltage direct current
  • the mass-impregnated cable is the oldest type of high voltage cables used. Already at the turn of the century, some 100 years ago, such cables were in use for voltages up to 10 kV. Later, - the voltages increased thanks to improvements of the insulating materials as well as to development of the required production processes.
  • the insulation is heat cycled when the cable is loaded and unloaded.
  • the impregnant masses expands as a result of heating caused by conductor -, dielectric -, sheath - and eventual armour losses. This expansion can generate high pressures if opposed by the enclosing sheath and reinforcement. The lead sheath cannot sustain such high pressures and would experience plastic deformation without additional reinforcement.
  • the temperature drop is highest in the conductor, so that mass will be sucked into it, depleting the surrounding insulation of mass, creating vacuum bubbles and wholly or partly empty spaces in the insulation.
  • low pressure gas is a much worse insulator than oil and also has a much lower dielectric permittivity it will be subjected to voltages in excess of its withstand capability and partial discharge will result.

Abstract

La présente invention se rapporte à un câble d'alimentation électrique à courant continu à haute tension (1) comprenant - au moins un conducteur multifils (2), - au moins une couche isolante (3) englobant le conducteur et consistant en une pluralité de rubans perméables enroulés autour du conducteur; au moins une gaine non perméable (4) englobant le conducteur isolé; et un composé d'imprégnation remplissant sensiblement tous les interstices à l'intérieur du conducteur, et le système d'isolation comprenant tous les interstices entre les couches individuelles de bande et tous les vides à l'intérieur même de la structure de la bande. Le composé d'imprégnation possède une très forte pente de modification des caractéristiques de viscosité; la viscosité étant élevée - avec une structure de type gel solide - à des températures inférieures ou égales à la température maximale de fonctionnement du câble (1) et étant faible - avec une structure de type liquide peu épais - à des températures plus élevées. Le composé a une viscosité de 1-3 Pas et plus, dans la gamme de températures inférieures ou égales à une température maximale de fonctionnement du câble conducteur et une viscosité de 0,1 - 0,3 Pas et moins, dans la gamme de températures supérieures à ladite température du câble conducteur plus 5 - 25 K. Le câble peut s'adapter à différentes températures ambiantes en ajustant la combinaison des matériaux du système isolant. L'invention se rapporte également à un procédé pour fabriquer le câble et le composé d'imprégnation.
