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.

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.

A transformer device includes a transformer circuit having a shape arranged to be connected to another transformer device, and a connector provided on one side of the transformer circuit such that the transformer circuit is connected to a cable connected with another transformer device where the transformer circuit is configured to be connected to a transformer circuit of another transformer device through the cable to increase a voltage or current provided to a load.
