A coaxial cable includes a non-conductive core and a first flexible copper conductor which surrounds the non-conductive core and is used as an inner conductor of the coaxial cable. Insulation is provided around the first flexible copper conductor. A second flexible copper conductor which surrounds the insulation and serves as an outer conductor of the coaxial cable.

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.

A wiring component with physical quantity sensor is provided with a plurality of electric wires, a physical quantity sensor for detecting a physical quantity of the plurality of electric wires, an electric wire holding member including an intervening portion interposed between the plurality of electric wires, and a holder holding the physical quantity sensor. The electric wire holding member includes a protrusion protruding from the intervening portion in a direction perpendicular to an arrangement direction of the plurality of electric wires, and aligning the holder in longitudinal directions of the plurality of electric wires by the protrusion. The holder includes an electric wire engaging portion being engaged with at least one of the plurality of electric wires.

The present disclosure provides a cable, a cable cooling device, and a vehicle. The cable includes a cable body and a cooling jacket, where the cooling jacket is wound around the cable body; and the cooling jacket is provided with a lumen, is connected to an inlet joint of water and a return joint of water which communicate with the lumen, and is constructed so that cooling liquid enters the lumen through the inlet joint of water and flows out through the return joint of water. With the present disclosure, the technical problem that the cable is difficult to cool is solved.

Methods, apparatus, and systems for indicating cable temperature with chromogenic polymer coatings include determining, based on a temperature threshold, a material for a chromogenic polymer coating, wherein the chromogenic polymer coating is configured to change color based on a temperature of the chromogenic polymer coating exceeding the temperature threshold, and applying the chromogenic polymer coating to a surface of a cable.

A conductor includes a strength member including a core formed of a composite material. An encapsulation layer is disposed around the core. A groove may be defined in at least one of the core or the encapsulation layer. An optical fiber assembly is disposed in the groove, and includes a fiber core and a fiber encapsulation layer disposed therearound. A conductor layer is disposed around the strength member. A sensing element may be disposed within the fiber core at a pre-determined location along a length of the fiber core. A system may include a controller communicatively coupled to the optical fiber assembly to determine a value or change in a value of the operating parameter of the conductor. The system is configured to independently determine at least two different operating parameter of the conductor with high precision. A coupler may be coupled to an axial end of the conductor.
