A signal and power cable is provided with a plurality of twisted pair conductor elements, at least one of which is configured for power transmission and at least one of which is configured for signal transmission. At least one cable filler element is configured to at least partially separate one of the plurality of twisted pairs from another, the at least one cable filler element having at least one hollow opening. At least one optical fiber, the at least on optical fiber positioned within the at least one hollow opening of the at least one cable filler element.

Bundled cables and methods for preparing bundled cable are disclosed herein. In the method, a plurality of subunits is wound about a central member. The subunits include a subunit jacket made of a first thermoplastic composition and has a first outer surface, and the central member includes a central member jacket made of a second thermoplastic composition and has a second outer surface. A metal element is provided at an interface of the second outer surface and the first outer surface of the subunits. The metal element is heated such that at least one of the first thermoplastic composition or the second thermoplastic composition forms bonds with the other of the first thermoplastic composition or the second thermoplastic composition.

A sensor system for an electric power asset includes a sensor instrument coupleable to sensors associated with the electric power asset to receive sensor signals therefrom, and an antenna connection cable coupled to the sensor instrument. The antenna connection cable includes a cable sheath and a plurality of twisted pair signal carriers contained within the cable sheath to carry sensor signals received from the electric power asset. A first subset of the plurality of twisted pair signal carriers carry antenna signals and a second separate subset of the plurality of twisted pair signal carriers carry signals for partial discharge monitoring.

A high frequency signal transmission cable includes a conductor, an insulator provided over a periphery of the conductor, a plating layer provided over a periphery of the insulator, and a sheath provided over a periphery of the plating layer. A crack suppressing layer includes a non-cross-linked polyethylene is provided between the insulator and the plating layer, in such a manner as to remain in contact with the insulator while being provided with the plating layer over an entire periphery of a roughened outer surface of the crack suppressing layer. The crack suppressing layer is unadhered to the insulator. The plating layer is adhered to the crack suppressing layer. The crack suppressing layer suppresses an occurrence of a cracking in the plating layer by bending together with the plating layer while being integral and moving with the plating layer in a longitudinal direction of the cable.

An electrical cable includes a conductor assembly having conductors and an insulator. The electrical cable includes a cable shield wrapped around the conductor assembly having an inner edge at a first end segment and an outer edge at a second end segment. The second end segment is wrapped over the inner edge and the first end segment to form a flap covering the inner edge and the first end segment. The second end segment forms a void at the inner edge. The electrical cable includes a void shield on the outer surface between the insulator and the cable shield. The void shield extends between a first end and a second end. The void shield is aligned with the void and spans entirely across the void. The cable shield is electrically connected to the void shield.
