PROBLEM TO BE SOLVED: To provide a resource saving system which reduces copper wires for coil winding (178,000 ton used in a year in the fiscal year 2000) and electromagnetic steel plates (2,000,000 tons used in a year) each down to half the level every year, when energy saving and resource saving are called for now due to global warming and everything is requested to be used efficiently and in a resource-saving manner. SOLUTION: A home electronic apparatuses used exclusively at 120 Hz is arranged by each area (2), and in a factory, an industrial apparatus is made, and power is supplied from a power distributing facility of 120 Hz. This is a 120 Hz power system, and for the electrical apparatus used here, a copper material or an iron material among all the principal materials is half the conventional one, and this is an economical 120 Hz power delivery area system which is constituted of a small and light-weight resource saving apparatus. |
