Researchers at Arizona State University have invented a high phase order electrical cable conductor capable of high or low power level operation. The design consists of a polyphaser AC electric power cable suitable for transmission, sub-transmission, and distribution. The essence of the design is a multilayer configuration in which the placement of the polyphaser conductors are such that desirable line impedance characteristics are attained. Electrical phase conductors are placed in specific locations so the cable impedance can be set to a desired level. Enhancing mutual coupling between the phases reduces the positive sequence impedance, which enhances the power transfer capability.

Benefits and Advantages
- Energy Efficiency – Removes the need for phase manipulation through combining/splitting multiple three-phase components, reducing energy losses.
- Reliability – Circuits are able to operate with one or more phases removed from service, eliminating a major cause of blackouts and grid failures.
- Lower Costs – Lower voltage phase to phase allows for less insulation between phases, cutting manufacturing costs.
- Capacity – Use of higher phase orders increases the power capacity of the cable and allows for more compact and higher power density cable.
