TMC Transformers manufactures dry type transformers and reactors for all applications worldwide, such as industry, building and infrastructure, traction substations, marine and offshore, oil and gas, renewable energy, battery storage, mining, and data centres.

TMC has a large customer base, which has led to the development of all types of customized solutions in the world of dry transformers. This experience has enabled the development of creative projects adapted to customer needs, both in transformers for indoor and outdoor installation that are able to reach operating temperatures of -50°C and incorporating different cooling systems (natural air, forced with exchangers, air-water or air-air).

TMC invests heavily in research and development. Dry transformers continue to evolve with respect to new materials, resins, types of insulation, and cooling systems.

In fact, a team of technical experts — electrical and mechanical engineers — make new developments and solutions possible for our customers.

Tools and methods such as finite element analysis ensure the highest quality products capable of withstanding short-circuit mechanical stresses and maintaining operational reliability.

The network transformers

The Dry Type Submersible Network Transformers is suitable for application in underground vaults under sidewalks in densely populated cities. In case of heavy rain, these vaults may be flooded, so the transformers are located inside completely sealed tanks. Dry type submersible network transformers do not contain oil, preventing the risk of fire propagation in the cities. They consist of a fully welded tank and are supplied with an external tap changer that facilitates voltage regulation according to the network. The footprint is similar to liquid-filled units, so they are can be easily interchanged.

Network transformers are the ideal solution for supplying and distributing energy within infrastructure projects aimed at high efficiency and fire safety. The insulation system is flame retardant and self-extinguishing, making them a safe and reliable choice over combustible fluid-filled transformers.

At the exhibition, TMC plans to promote the network transformers developed by the company’s R&D team, interact with customers, share experiences, and advise customers on TMC’s full range of solutions and products related to dry transformers.
