Abstract: A continuously transposed conductor (CTC) cable may include a plurality of electrically insulated strands arranged in first and second stacks with the plurality of strands successively transposed between the first and second stacks. The plurality of strands may include at least one strand having a plurality of component strands that are arranged in third and fourth stacks with the plurality of component strands successively transposed between the third and fourth stacks. Each of the components strands may include a conductor and insulation formed at least partially around the conductor.

Abstract: Insulated winding wires and associated methods for forming winding wires are described. A winding wire may include a conductor and insulation formed around the conductor. The insulation may provide a partial discharge inception voltage greater than approximately 1,000 volts and a dielectric strength greater than approximately 10,000 volts. Additionally, the insulation may be capable of withstanding a continuous operating temperature of approximately 220° C. without degradation. The insulation may include at least one base layer formed around an outer periphery of the conductor, and an extruded thermoplastic layer formed around the base layer. The extruded layer may include at least one of polyetheretherketone (PEEK) or polyaryletherketone (PAEK).

Abstract: A continuously transposed conductor (CTC) cable may include a plurality of electrically insulated strands arranged in two stacks with the plurality of strands successively transposed between the two stacks. Each strand may include a conductor and insulation formed at least partially around the conductor. Additionally, each strand may have a cross-sectional area that is less than approximately 0.0030 square inches. As a result, the CTC cable may be suitable for use in electrical devices relatively smaller than those associated with conventional CTC cables.

Abstract: An insulated winding wire may include a conductor and insulation formed around the conductor. The insulation may include a base insulation layer formed around the conductor and having a first dielectric constant (?1). The insulation may further include an extruded thermoplastic layer formed around the base insulation layer and having a second dielectric constant (?2). The extruded thermoplastic layer may include (i) at least one polymer comprising a ketone group and (ii) at least one fluoropolymer. A ratio of the dielectric constant (?2) of the extruded thermoplastic layer to the dielectric constant (?1) of the base layer at 250° C. may be less than or equal to approximately 1.0.

Abstract: An insulated winding wire may include a conductor and a plurality of adjacent layers of semi-conductive material formed around the conductor. First and second layers of semi-conductive material included in the plurality of adjacent layers may have different conductivities. For example a first layer of semi-conductive material may have a first conductivity, and a second layer of semi-conductive material may have a second conductivity lower than the first conductivity. Additionally, at least one layer of insulation material may be formed around the conductor, for example, on the second layer of semi-conductive material.
