  • Overhead lines are designed either as three-phase systems or as high-voltage direct current (HVDC) transmission.
  • the routes consist of steel cables that are wrapped in aluminum.
  • the problem here is the strong external fields, the lower insulation resistance due to the presence of humidity and the corona losses due to the very high field strength at the wire surface.
  • Earth cables have a 40% lower ohmic resistance due to the use of copper, but as a three-phase system they have a significantly higher reactive power component due to the capacitive coating of the cable, which can only be compensated outside the transmission path. They are therefore designed as an HVDC system, especially as an overseas vessel.

  • SF 6 climate-effective gas
  • the object of the present invention is to provide a device by means of which electricity can be passed under high voltage and low-loss data, this device should be highly resistant to environmental influences and maintenance-free. Another object is to provide a method of making this device.
  • a device for conducting power under high voltage and for data transmission, comprising at least: a protective tube which is lined with an insulating mass comprising a plastic-bound silicate filling material,
