| Abstract | The modern principles of Integrated Product Policy, as expressed in the European Commission Green Paper, share the responsibility of a product among all the actors of every phase in its life cycle. Because of ENEL Company’s role of electricity producer and distributor, the environment protection is not only due to the observance of national regulations but is considered an element of its firm decisional process, as expressed in the Environmental Reports 19971998. In the last few years many efforts have been made to optimize the main components of the distribution network concerning electrical and environmental performance. New equipment have been designed in order to improve the quality of service to consumers, to anticipate the evolution in standards and the demands of the market and to reply to the growing environmental awareness. The inclusion of SF6 in the “basket” of six greenhouse gases by Kyoto Summit on Climate Change, the European Directive on Waste Electrical and Electronic Equipment (WEEE), the Italian valuable landscape safeguard led to more compact solutions, with a larger recycling and a lower SF6 content, taking advantage of prefabrication to reduce disturbance to the environment and land use. The application of this policy was assumed also for MV metal-enclosed switchgears, used in HV/MV distribution substations. These devices clearly have a role of primary importance in maintaining the availability of electrical power and for safety of life. They contain the electric power control and supervision functions in public and industrial plant distribution system and must perform isolation, operating and protection functions on outgoing line feeders at a high level of reliability. Two years ago in order to reduce space requirements of HV/MV substations and in turn of SF6 insulated switchgears, an air insulated double-level panel switchgear and an air insulated compact switchgear were designed with modern technologies, low cost and reduced dimensions to be accomodated in a prefabricated building. In order to understand the environmental impacts related to the whole life cycle of these new switchgears and of a SF6 insulated switchgear a comparative LCA was performed. The assessment was developed by CESI for ENEL Distribuzione of Italy, in search of critical points and the identification of the most environmental-friendly solution. |
