High voltage direct current transfer line for laying in deep sea areas comprises a long sodium cylinder enclosed by a one or more layer thick-walled insulating tube, connecting elements and short connecting tubes

摘要

High voltage direct current transfer line comprises a long sodium cylinder (1) enclosed by a one or more layer thick-walled insulating tube (2) made from plastic such as polyethylene or polypropylene, connecting elements (3) and thick-walled short connecting tubes (4) made from one or more layer plastic and sinking weights (5) arranged on an island. The connecting tubes are pressed together so that the ends of the tubes are away from the connecting sites. The connection is water-tight. Preferred Features: The connecting elements are large cylinder pins made from metal such as aluminum or copper.
