Continuously transposed conductor cables include a plurality of electrically insulated strands that are formed into two interposed stacks. Each of the plurality of strands may successively and repeatedly taking on each possible position with a cross-section of the CTC cable. Additionally, an optical fiber may be incorporated into the continuously transposed conductor cable.

A ribbon cable having an additional conductor track for breaking detection, includes a carrier film having at least one electrical conductor track, wherein the carrier film has a first connection region at a first end and a second connection region at a second end, wherein the first connection region can be arranged between the two panes of a laminated pane and the second connection region can be guided out of the laminated pane between the two panes, and wherein the electrical conductor tracks can electrically contact an electrical functional element in the first connection region, wherein the carrier film has an additional conductor track which is designed to be loop-shaped, so that an ohmic resistance between the two ends of the additional conductor track can be measured.

Systems, methods and tools for the interrogation of fiber-reinforced composite strength members to assess the structural integrity of the strength members. The systems and methods utilize the transmission of light through optical fibers that are embedded along the length of the strength members. The inability to detect light through one or more of the optical fibers may be an indication that the structural integrity of the strength member is compromised. The systems and methods may be implemented without great difficulty and may be implemented at any time in the life cycle of the strength member, from production through installation. The systems and methods have particular applicability to bare overhead electrical cables that include a fiber-reinforced strength member.

A power supply facility includes a feeder cable disposed along a moving path of a movable body and configured to contactlessly supply electric power to the movable body, and a heat sensitive unit disposed along the moving path together with the feeder cable. The feeder cable includes a conductor bundle bundling up a plurality of conductor lines through which an alternating-current flows, and an insulating coating covering the conductor bundle. The heat sensitive unit includes a first heat sensitive wire contained inside the insulating coating of the feeder cable and extending along an extending direction of the feeder cable together with the conductor bundle; and a second heat sensitive wire disposed at a position next to the feeder cable and extending along the extending direction of the feeder cable together with the feeder cable.

A covered wire includes a wire including a metal, a covering layer provided at a periphery of the wire, and inclusions including at least one of a metal and a metal oxide. The inclusions are provided between the wire and the covering layer or in the covering layer, and an average size of each of the inclusions is less than a thickness of the covering layer.

A continuously transposed cable CTC, extending according to a longitudinal development direction (L) and having two opposite longitudinal ends, includes a plurality of strands arranged so to form at least a first and a second adjacent stacks, each extending along the longitudinal development direction (L), wherein said at least first and second stacks form a longitudinal interface therebetween. The CTC cable (1) further includes one or more optical fibers positioned at the interface between the first and the second stacks. A winding of an electromagnetic induction device, such as a transformer, can be obtained by winding said CTC cable.

A system for detecting water trees in branching underground electrical cables includes a pulse generator configured to inject a pulse into a first underground cable that branches into a second underground cable and a third underground cable. The system includes a first sensor associated with the first cable, a second sensor associated with the second cable, and a third sensor associated with the third cable. The system includes a control device configured to obtain a first, second, and third signal associated with the first, second and third sensors, respectively. The control device determines a lead-lag relationship between the second and third signals and determines presence of a water tree within at least one of the second and third cable based on the lead-lag relationship. When presence of a water tree is determined, the control device generates a control action associated with repairing or replacing the second and/or third cable.
