The present invention relates to a non-metallic light conductive wire, a composite conductive wire, a special cable, a motor and the like application products made of the conductive wire, and a method of making the composite conductive wire.

A system and a method are presented. The system includes an electrically conducting material and an electrical insulation system. The electrical insulation system includes a layered insulation tape that has a first layer and a second layer. The first layer includes a mica paper and a binder resin in a range from about 5 wt % to about 12 wt % of the insulation tape. The second layer includes a composite of layered nanoparticles dispersed in a polyetheretherketone (PEEK) matrix. The second layer laminates the first layer. The method includes attaching the first layer and the second layer with or without the addition of further resin; using the layered insulation tape as a turn insulation and ground wall insulation for an electrically conducting material; and impregnating the system with a nanofiller-incorporated resin by a vacuum pressure impregnation method, to form an insulation system within the system.

A helically wound insulated twinax cable reduces cable dielectric loss by increasing the percentage of air in the dielectric filler surrounding the signal conductors. The helical insulator wire winding further provides mechanical support and reduces the risk of creating an electrical short-circuit. This will improve differential signaling capability of the two-conductor cable and enable longer cable range.

A twin-axial cable includes (1) a first primary comprising a first signal conductor surrounded by a dielectric and (2) a second primary comprising a second signal conductor surrounded by a dielectric. The twin-axial cable also includes a different dielectric is wrapped around the exterior of both of the first and second primaries.

An electrical cable includes a conductor and a couple of mica tapes surrounding the conductor. The couple of mica tapes are formed of a first mica tape and a second mica tape wound around the first mica tape. Each of the first and the second mica tape includes a mica layer attached to a backing layer. The mica layer of the first mica tape faces and contacts the mica layer of the second mica tape.
