  • Patent number: 4181815
    Abstract: An electrical cable of the self-floating type for use in marine environments is provided with elements for taking up mechanical tractive forces. The electrical conductors of the cable are surrounded by an inner friction layer with a low friction coefficient. Around this layer a force equalizing layer of metallic material is provided and this layer is surrounded by a tube of plastic material showing a number of circumferentially situated grooves. An outer friction layer of the same material as the inner friction layer surrounds the hollow strands and the whole system together with the elements for taking up the tractive forces is embedded by a cable mantle of rubber-like plastic material.
    Type: Grant

The electrical conductors of the cable are surrounded by an inner friction layer with a low friction coefficient. Around this layer a force equalizing layer of metallic material is provided and this layer is surrounded by hollow strands of soft plastic material. An outer friction layer of the same material as the inner friction layer surrounds the hollow strands and the whole system together with the elements for taking up the tractive forces is embedded in a cable mantle of rubber-like plastic material.
