The present application provides a zero-buoyancy cable, which comprises a cable; a plurality of floats sheathed on the cable; and a cladding layer configured to tightly wrap the plurality of floats and the cable so as to fix the floats onto the cable. The zero-buoyancy cable provided in the present application can effectively avoid the loss of the float or the sliding of the float on the cable, thereby improving the balance of the zero-buoyancy cable in the water.

Power umbilical (1) comprising a plurality of power cables (7) for electric power transmission, elongated filler elements (5), and an outer sheath (3). The elongated filler elements (5) abut against each other at abutment faces (5a), thereby forming a complete ring enclosing the power cables (7). The elongated filler elements (5) comprise cable recesses (5b) within which the power cables (7) are embedded. The power umbilical (1) further comprises one or more friction control profiles (13, 15, 116), wherein the material of the friction control profile (13, 15, 116) is softer than the material of the elongated filler elements (5). The one or more friction control profiles (13, 15) are arranged in a deformed state.

The present invention concerns a power cable, comprising a tension member (1), placed in the centre of said power cable; a first insulation layer (3), the tension member (1) being embedded in the first insulation layer (3); and an outer protective sheath (9); wherein said power cable further comprises one or more first aluminum conductors (4), embedded within the first insulation layer (3). The present invention also concerns a process for producing the inventive power cable, the process comprising the step of extruding a first polymeric insulation layer (3) onto the tension member (1) and the one or more conductors (4) in one single step. Finally, the present invention concerns the use of the inventive power cable, in medium-voltage to high-voltage subsea applications, such as an offshore windmill cable infrastructure or driving of subsea pumps.

The present invention relates to an interface-forming device (x60) and a method for providing an electrically conductive power transmission interface (x30) on the end surface of a power cable (xOO) having at least two separate wires (x02) being electrically conductive, the cable (xOO) further comprising a reactive compound different from the wires (x02) for providing further features to the power cable (xOO). The method comprises the steps of providing an end section of the power cable (xOO), the end section comprising wires (x02) having wire ends, the end section further having the reactive compound, and successively adding electrically conductive particulates (x67A) onto the end section by bringing the conductive particulates being dispersed in a carrier fluid of a different material than the conductive particulates into contact with the end section. Thereby, cable joining and terminations are achieved of a higher quality.
