Tamini is presenting the “Green” Transformer Project for the first time

The "Green" Transformer, an Autotransformer of 250 MVA and 400 kV designed and manufactured by Tamini, is an innovative product environmentally sustainable and eco-efficient, isolated to ester oil instead of with mineral oil. The product provides benefits to the environment and health by committing to preserve the environment, providing:
• an increase in the transformer life due to a longer cellulose based insulation life present inside;
• a limited risk of pollution (in case of spillage or loss) because the ester oil is biodegradable and less toxic and limits the risk of pollution during operation, installation and end of life;
• a greater safety (toxicity and anti-fire), because the ester oil has a higher flash point greater than double that of mineral oil. This makes it possible to practically reduce the possibility of fire ignition to zero as a result of a fault;
• a reduction of the impact related to the site construction due to smaller distances between transformers, collection tank no longer indispensable, even if still required by rules;
• an improvement of the efficiency and the environmental performance with the same nominal power.

This innovative Autotransformer with ester oil is the first one of this high power type on the market and we would greatly appreciate your taking the time to refer to the attached Environmental Product Declaration (EPD), drafted in compliance with the International EPD System: a further step towards the recognition of the qualities of innovation, efficiency and sustainability of this product.

The project was officially presented during two events of the last week: on the 20th of June at the Conference organized by the Italian Electrotechnical Committee (CEI) in collaboration with the University of Rome “Sapienza”; on the 22nd of June at the Itinerant Course on Green Metallurgy 2017 organized by the Italian Association of Metallurgy (AIM) and hosted by the Italian companies Feralpi Siderurgica, Tenova and Novelis Italia Spa.
