	Recycling Technology for Power Receiving and Distribution Substations
	R&D investigating committee on recycling technology for power receiving and distribution substations
	Power receiving and distribution substations, which connect power systems and customers, are widely used in industry, service, building and public facilities and therefore must be highly reliable. In recent years, demands for control of capital investment have led to substations being used up to their maximum lifetimes, with the appropriate management. However, even with such management, substaions and equipments are eventually replaced or disposed of. From the viewpoint of reducing the burden on the environment, the social responsibility of corporate bodies using or manufacturing these substations and equipments is increasing with regard to appropriate treatment of industrial waste. With this background, the R&D investigating committee studied the present state of recycling and technology development for power receiving and distribution substations of voltages of 66/77 kV and below including for control equipments. The following results on recycling and new technology are summarized in the technical report; 1) the present state of recycling for power receiving and distribution substations, 2) the state of recycling as seen from a legal viewpoint, 3) newly developed technology for the reduction of environmental effects and 4) the actions of users. For this study on recycling technology, the committee visited many parts of the recycling process and the results found will likely be beneficial for business operation. New technology for the reduction of the burden on the environment is also summarized. This report may prove useful to those people who manage, manufacture or develop power receiving and distribution substations by providing information on the proper treatment for obsolete substaions.
