ABSTRACT:
The invention provides a multiple parallel conductor for windings of electrical motors, including transformers, having individual insulated partial conductors with at least five partial conductors or transposed conductors. The multiple parallel conductor features a material that is partially wrapped about the individual insulated partial conductors for allowing cooling fluid to pass through the individual insulated partial conductors. The material is partially wrapped about the individual insulated partial conductors in a helical configuration. In one embodiment, the material is an aramid material such as Nomex.TM..
