High-performance Dry-Type Transformers
TMC Transformers is entirely dedicated to the development and production of dry type transformers. This exclusive focus allows us to deliver highly specialized solutions, carefully studied and shaped to meet every possible customer requirement based on specific technical and installation needs. Whether for medium or low voltage, we combine our technical expertise with a rigorous commitment to environmental sustainability.
Our dry type transformers are designed for maximum safety, energy efficiency, and long-term reliability, making them the ideal and modern choice for power distribution systems.
What is a dry type transformer?
Dry type transformers use air or resin-based insulation instead of oil. The windings are either vacuum pressure impregnated (VPI) or encapsulated in cast resin, making them ideal for indoor use and sensitive environments. This technology eliminates the risk of oil leaks, reduces fire hazards, and simplifies maintenance. Dry type transformers are widely used in hospitals, data centres, public buildings, and renewable energy systems due to their low environmental impact and high reliability.
Push the boundaries
At TMC Transformers, we push the boundaries of this technology by making dry type transformers suitable even for outdoor installations. Thanks to our focused engineering on this single product line, we can manufacture dry type transformers that perform reliably even in extreme environmental conditions. Discover how, clicking here.

Dry type transformers – Key benefits
Dry type transformers offer a series of advantages over traditional oil-filled units, especially in terms of safety, sustainability, and ease of installation.
- One of the most significant benefits is the absence of flammable liquids, which drastically reduces the risk of fire and makes dry type transformers safer for indoor and densely populated environments.
- From an environmental perspective, dry type technology eliminates the possibility of oil leaks and soil contamination, making it a cleaner and more sustainable choice.
- In terms of maintenance, dry type transformers require significantly less attention. There’s no need for oil level checks, replacements, or leak monitoring, which translates into lower operating costs and fewer service interruptions.
- Installation is also more flexible: dry type transformers can be placed in confined spaces without the need for special containment or ventilation systems.
- Finally, when considering lifecycle costs, dry type transformers tend to be more economical over time due to their durability, reduced maintenance, and improved safety profile.
