Grupo Corporativo Mayo started doing business in Argentina in 1970, when it began manufacturing transformers. Then, activities were incorporated to supply the Argentinian and South American electrical market, among which we mention the manufacturing of fittings for low and medium voltage lines, the manufacturing of impregnated wooden eucalyptus poles for power lines and the distribution of various electrical materials. The Transformers division of Grupo Mayo has extensive experience in the electrical market, designing and manufacturing transformers for more than 40 years. In parallel, it made investments in the production chain, which enabled us to have different manufacturing facilities for tanks, radiators and silicon steel cores.
