Cast resin transformers, also known as resin power transformers, are electrical distribution devices designed to ensure reliability, safety, and optimal performance in various applications.

They feature a core made of grain-oriented steel sheets less than 300 micrometers thick and medium-voltage windings fully encapsulated in epoxy resin, an insulating material with excellent mechanical, chemical, and electrical properties.

Epoxy resin provides resin-encapsulated transformers with exceptional corrosion resistance, making them particularly suitable for installation in critical environments exposed to harsh weather conditions, such as industrial areas, coastal zones, or high-humidity environments.

In addition, resin-encapsulated power transformers are designed to operate without the need for constant maintenance, making them practical and cost-effective devices for urban, naval, railway, and industrial applications.

Thanks to their high protection rating and compact design, resin transformers are also ideal for installations in tight spaces, where optimizing available space is essential. Furthermore, their ability to withstand temperature fluctuations, dust, and vibrations ensures reliable performance over time.

Whether for urban distribution networks, installations in the naval and industrial sectors, or applications related to transportation systems such as rail systems, resin-insulated power transformers ensure superior power quality, contributing to improved efficiency and stability of the electrical system as a whole.
