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.
