A system and a process for continuously electrolytically coating a wire, useful for a high tension cable, is provided. The system includes a bath containing a precursor for an electro-ceramic coating on a wire and containing a cathodic connection, at least one motor connected to at least one motive assembly to impart movement to the wire. A power source provides high voltage and high current to the wire through the electrification device, and through the wire in the bath to the cathode connection via the aqueous electrolytic solution. The process includes electrifying bare wire with a high voltage and a high current, passing the electrified bare wire through a bath having a cathodic connection and containing an aqueous solution with a precursor for an electro-ceramic coating, and electrochemically reacting the wire with the precursor thereby generating a coated wire having an electro-ceramic coating on at least one surface.

A bus bar (1) comprises: a laminated conductive wire (20) formed by arranging side by side in the longitudinal direction a first plate-shaped conductive wire (21) formed by spirally winding stripe conductors (11, 12) mutually adjacent in the width direction while bringing the opposing inner surfaces closer to each other, and a second plate-shaped conductive wire (22) formed by spirally winding the stripe conductors (11, 12) in the direction opposite the direction of the first conductive wire (21) while bringing the opposing inner surfaces closer to each other, and overlapping these wires (21, 22) so that the outer surfaces in the width direction face each other; and terminals (30) joined to the first conductive wire (21) and the second conductive wire (22) at both ends of the laminated conductive wire (20).

Disclosed is a non-steel high strength data transmission cable having a strength member (5) and a core (1). The high strength data transmission cable includes a length of a core-cable (10), the length of core-cable (10) includes core (1) plus at least one fiber-optic conductor (2) that is: (i) disposed in a helical shape; and (ii) completely encased in a solid, flexible material. Also disclosed is a process for making a high strength data transmission cable. The high strength data transmission cable is capable of being wound on a winch under tensions and surging shocks experienced by a fishing trawler, and provides high quality data signal transmission and resolution so as to permit use for transmitting data during fish trawl operation from high-resolution sonars used to monitor fish caught.

Disclosed herein are exemplary embodiments of electrically insulated conductors and exemplary methods for electrically insulating conductors, such that the resulting electrically insulated conductors are resistant to partial discharge (PD), and thereby suitable for PD resistant design schemes (e.g., 800 V or above electric motors, etc.). An exemplary method includes applying an enamel coating along an electrical conductor, wrapping an electrically insulative tape around the enameled electrical conductor, and heating sealing the tape-wrapped, enameled electrical conductor to help ensure good adhesion of the electrically insulative tape to the enamel coating. The electrically insulative tape comprises polyimide and a sufficient amount of an electrically insulative, corona resistant filler for PD resistance. The tape-wrapped, enameled electrical conductor is resistant to partial discharge (PD), e.g., suitable for use in a stator winding of an 800 volt or above electric motor, etc.

A processing apparatus 200 for a multicore cable 1 processes the multicore cable 1 including a sheath 2 and cores 3 and 4 inserted in the sheath 2, and includes: a slitter 21 that makes a slit along a circumferential direction; a puller 22 that moves at least one of a distal portion of the sheath 2 and a proximal portion of the sheath 2 in a longitudinal direction of the multicore cable 1 to thereby expose the core wires 3 and 4, the distal portion being closer to a distal end of the multicore cable 1 than the slit, the proximal portion being closer to a proximal end of the multicore cable 1 than the slit; a detector 31 that detects a position of a specific core 3 of the cores 3 and 4 in a circumferential direction of the multicore cable 1; and a rotator 32a that rotates the multicore cable 1 based on the detected position of the specific core 3 in the circumferential direction to thereby move the specific core 3 to a predetermined position in the circumferential direction.
