Special Dry-Type Transformers
At TMC Transformers, we are a trusted special transformers manufacturer with extensive expertise in the design and production of cast resin transformers for the most demanding technical applications.
Engineered to meet your unique requirements up to 25MVA and system voltages up to 52kV, our tailor-made dry transformers ensure maximum performance, reliability, and efficiency across diverse industries such as energy, infrastructure, transportation, renewables, and heavy industry.
Thanks to the use of epoxy resin, our transformers deliver superior performance and enhanced short-circuit resistance. We offer maximum flexibility in the choice of winding materials, with aluminium or copper options, to adapt to different project specifications. In addition, our insulation systems, available in class F or class H, guarantee durability and safety in demanding conditions.
Advanced engineering with FEA and multiphysics simulations
As a testament to our deep expertise in dry-type transformer technology, TMC relies on a dedicated team of engineers specialized in Finite Element Analysis (FEA) and multiphysics simulations.
Through these trials, we refine transformer geometries, select the most suitable materials, and optimize winding configurations, while accurately modeling the complex interactions between electromagnetic, thermal, and mechanical forces. This process ensures that each transformer fits with customer-specific requirements.
Based on the above, the reason why simulations are an essential element in transformer design is evident. The more complex an object becomes and/or deviates from a standard construction, the more critical it is to simulate its real operation according to the conditions required. Indeed, to ensure that the machine aligns with the requirements, the customer usually asks for a test, often commissioned by a certified third-party laboratory, resulting in a significant cost increase. With multiphysics analysis running on the finite elements, we always provide the customer with a very detailed report of the analysis, which provides proof and guarantees that the machine meets the specific requirements of the clients.
Key Features of TMC Special Transformers
Beyond the advanced engineering and customization described above, one of the main reasons to choose TMC lies in our ability to adapt dry-type transformers for outdoor use in even the harshest environments. Over the years, we have developed dedicated protective solutions that ensure reliable operation in areas exposed to wind, salty air, industrial pollution, or urban smog: discover more about our protective enclosures and specialized cooling technologies by visiting the dedicated pages.
Equally important is our strong focus on research and development, supported by comprehensive in-house testing capabilities.
Thanks to our anechoic chamber and state-of-the-art facilities, we not only perform all legally required tests but also conduct advanced laboratory checks tailored to customer needs. These include measuring short-circuit voltages, load and no-load losses, partial discharges, and winding resistance, as well as performing insulation tests, heating and pulse tests, and even noise assessments.
By combining multiphysics simulations with this rigorous internal testing, we can certify performance, guarantee compliance with international standards, and provide customers with clear, reliable proof that every transformer has been engineered to operate safely and efficiently in its environment.
