Abstract
Marine electrical cable apparatus has a flexible cable jacket loosely containing cable conductors and filled with a relatively incompressible fluid such as oil. The jacket flexes with changes in the environmental pressure to transmit that pressure to the inner fluid and thereby maintain minimal pressure differential across the jacket walls. Terminations at each end of the cable seal the jacket interior from the environment and feed the cable conductors from within the jacket out for connection with further electrical equipment.
