Megavoltampere
52 kV Class
max. rated voltage
Our cast resin dry-type transformers enable efficient energy distribution without the use of liquid coolants, making them particularly suitable for indoor and environmentally friendly applications.
These transformers are equipped with advanced insulation technology and are characterized by high reliability and minimal maintenance.
Our cast resin dry-type transformers are specially designed for use in high altitudes, high humidity, and harsh environmental conditions. They comply with international guidelines.
As these transformers do not contain flammable liquids and are made from materials that can self-extinguish, high environmental safety is ensured.
Furthermore, they do not emit toxic gases and are characterized by low electromagnetic emissions.

ECONOMICAL & SAFE - MAXIMUM PERFORMANCE WITH MINIMAL RISK
Our transformer offers numerous advantages that both lower operating costs and increase longevity. Thanks to its design without liquid filling, there is no risk of leaks, reducing maintenance requirements to a minimum.
Additionally, local customer service is provided for quick and easy support when needed. With its low transport and installation costs, the transformer is a cost-efficient solution, ideal for locations near shopping centers. Cooling fans allow the transformer’s rated power to be flexibly increased, while the low partial discharge ensures a long lifespan.
A high degree of insulation reliably protects against short circuits and lightning strikes. Additionally, short-term overloads are easily tolerated, offering extra security during peak load periods.
Our products provide a durable and reliable solution for maximum economic efficiency and safety. Slow thermal and dielectric aging significantly extends the lifespan.
Thanks to innovative design, we enable continuous development using new, high-quality materials. Maximum performance goes hand-in-hand with low energy consumption, reducing operating costs. Our space-saving design allows for easy integration, while self-extinguishing properties and high resistance to strong shocks and vibrations provide additional safety.
High mechanical protection prevents short circuits, while the high capacity reliably excludes overloading.
Trust in quality that pays off – economically and safely.
