Definitions

  • corrugated metal tubing Such enveloping has been provided for high power cables as well as for communication cables.
  • the jacket or envelope'of such a cable is usually made of steel or copper; aluminum is also used occasionally.
  • Corrugated envelopes are more flexible than conventional lead or aluminum envelopes without corrugation. It is, furthermore, known to pressurize the interior of such envelope, using oil or gas as pressure medium.
  • the corrugated envelopes are usually chosen to have circular cross-section.
  • employment of eliptical tubing as pressurized jacket or envelope for cable has been suggested for reasons of improving expansion.
  • FIG. 2 illustrates details of a gass pressure cable in accordance with another example of the present invention.
  • an inner, tubular envelope 4 made from longitudinally paid strip that has been formed into a split tube, seam-welded along the edges of the resulting joint and corrugated.
  • Three conduits 6, 7 and 8 are provided.
