  • Joints for electric cables
    Patent number: 3939298
    Abstract: The thermal resistance of a joint for fluid filled electric power cables is reduced by transversely dividing the fluid-tight enclosure of the joint into three parts, electrically insulated from each other, namely two end parts each sealed to one of the cable sheaths and to a central part of low thermal resistance. The central part preferably has a cooling jacket. If an outer enclosure for the joint is provided its central part is made of low thermal resistance.
