Abstract

A feasibility study has been completed to assess potential applications of conducting polymers in the manufacture of power equipment. Ten areas were studied: solid and liquid dielectric cables, capacitors, rotating machinery, transformers, bushings, surge suppressors, vacuum interrupters, gas-insulated equipment, and other miscellaneous applications. Each application was rated according to technical impact, probability of success, economic impact, and time frame for implementation. Of the 32 potential applications proposed, the top ranking areas were: coating of dielectric films for capacitors, conducting compounds to cover conductors in rotating machines, surface coatings to dissipate charges in bushings, coatings for controlled surface conductivity in gas insulated equipment, and thermal history monitors. Finally, the issues that have to be resolved before conducting polymers can find use in the identified applications are discussed
