An improved electric cable is disclosed herein. The resistance of the electric cable of the present disclosure is surprisingly decreased despite a reduction in the cross-sectional area of the conductor when at least one metal slug is positioned at an end of the cable. Conductor wires, which may or may not be individually insulated, may extend around a metal slug or through an aperture of the slug. In combination with at least one metal slug, the cross-sectional area of individual wires or the amount of wires within a stranded wire cable may be substantially reduced without seeing an expected proportionate increase in electrical resistance, and surprisingly, a decrease in resistance may be observed.

The present disclosure relates to a power cable joint system capable of minimizing expansion, deformation or damage of a metal sheath restoration layer, which is formed of a material such as lead sheath, due to internal expansion due to heat generated in an intermediate connection part of the power cable joint system.

Disclosed is a cable assembly including at least one conductor and a metal sheath disposed over the at least one conductor, the metal sheath including a continuous strip of metal having a plurality of revolutions. A first revolution of the plurality of revolutions may include a first section having a curved profile extending into an interior cavity of the metal sheath, and a second section extending from the first section, the second section extending along a lengthwise axis, wherein a length of the second section, along the lengthwise axis, is at least two times as large as a diameter of the first section when the metal sheath is in a linear configuration. The first revolution may further include a third section extending from the second section, the third section including a free end terminating within a recess defined by a curved profile of a first section of an adjacent revolution.

An ultra-high-voltage DC power cable system capable of simultaneously preventing or minimizing electric field distortion, a reduction of DC dielectric strength, and a reduction of impulse breakdown strength due to the accumulation of space charges in an insulating layer of a cable and an insulating material of an intermediate connection part.

A composite cable includes a plurality of internal cables and a covering member covering peripheries of the plurality of internal cables. At least one of the plurality of internal cables includes at least one electric wire having a conductor, a first sheath covering a periphery of the at least one electric wire, a shield covering a periphery of the first sheath, and a second sheath covering a periphery of the shield.

The invention provides a semiconductive polymer composition comprising a) at least 30 wt% of an ethylene vinyl acetate copolymer; b) at least 25 wt% carbon black; and c) at least 2 wt% of an ethylene vinyl acetate copolymer with an MFR2 of at least 100 g/10 min; with the proviso that components (a) and (c) are different.

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.
