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.

Continuously transposed conductors and assemblies

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&#xb0; 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).

Insulated winding wire

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 (&#x3b5;). The insulation may further include an extruded thermoplastic layer formed around the base insulation layer and having a second dielectric constant (&#x3b5;). 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 (&#x3b5;) of the extruded thermoplastic layer to the dielectric constant (&#x3b5;) of the base layer at 250&#xb0; C. may be less than or equal to approximately 1.0.
