ABSTRACT:
A high voltage cable filled with an insulation gas under an operating pressure of more than 1 Bar, in which one or more conductors are supported by insulators, embedded in a tubular sheath of interconnected rigid elements and in which the gas-filled spaces of adjacent segments are connected together through a sealing element which is open under operating conditions and is closed when the pressures in the adjacent segments differ by more than a predetermined pressure difference.
