TMC Australia Transformers Manufacturing Company Pty Ltd - the original TMC - was established in Melbourne, Australia in 1936 as a manufacturer of oil cooled and dry type transformers by Francesco Nicoletti an Italian engineer who had emigrated to Australia.

In 1968, having recently graduated with a Mechanical Engineering degree from the University of Melbourne, Carlo Vaccari acquired TMC from his uncle Francesco Nicoletti. His leadership and high level of engineering input together with a philosophy on excellence has led to TMC to being recognised worldwide as one of the leading designers and manufacturers of static induction equipment.

Following rapid technological developments in the field of epoxy resins during the 1980s, TMC began specializing in vacuum cast epoxy resin transformers. Over the past three decades TMC has evolved as a top tier supplier to both domestic and international markets with products that enjoy a reputation for quality and reliability.

In 2000 TMC Australia licensed its brand in the establishment of a European based manufacturer to facilitate a direct channel to a wider international market as well as to gain access to raw material suppliers and other industry developments.

In 2013 full control was assumed in Transformers Manufacturing Company España S.A. (TMC Spain) thus bringing together the strength of TMC Australia’s engineering and meticulous manufacturing experience with the expansive production capabilities of the Spanish plant located in the Basque Region near Bilbao.

In 2013, the market reach of TMC Spain was predominantly domestic. Today more than two-thirds of its production is exported to either European countries or further afield to the Middle East, North America, South America and South East Asia.

The stability and success of TMC Australia over more than eight decades and the global expansion of TMC Spain over the past five years can be attributed to an ingrained tradition of engineering and manufacturing excellence which result in products of the highest quality and reliability.


The technical and production experience of TMC Australia and TMC Spain combine synergistically to facilitate the design and manufacture of the most sophisticated transformers and reactors in the most efficient and cost-effective manner.

This experience has enabled both businesses to expand locally and globally as each draws on the mutual strength and support provided by the other.

Since 2013, the technical knowledge of TMC Spain has been further boosted as draws on the expansive experience of TMC Australia. This has enabled the manufacture of larger, more complex transformers with ratings up to 30MVA and 66kV .

Simultaneously TMC Australia has secured access to a European base from which to source raw materials and selected componentry manufactured by TMC Spain providing it with high quality, cost effective solutions for its local Australian and Southern Hemisphere customer base.
