ABSTRACT:
A high voltage mass impregnated power cable to be used on land and in shallow waters by including in the cable construction a pressure body having a number of pressure tapes applied in several layers on a bedding between the metal sheath and the tapes. The pressure tapes have good elastic properties and may consist of high quality metal or a strong synthetic material and are applied with a short lay length. The pressure body maintains under all load conditions including no-load, an internal pressure on the cable insulation above atmospheric pressure and high enough to prevent creation of voids in the insulation.
