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 oriented grain steel sheets with a thickness of less than 300 micrometers and Medium Voltage windings fully encapsulated in epoxy resin, an insulating material with excellent mechanical, chemical, and electrical properties.

Epoxy resin provides the resin transformers with extraordinary resistance to corrosion, making them particularly suitable for installations in critical environments exposed to complex weather conditions, such as industrial areas, coastal zones, or high humidity environments.

Additionally, resin power transformers are designed to operate without the need for constant maintenance, which makes them practical and cost-effective devices for urban, naval, railway, and industrial applications.

Thanks to their high protection class and compact design, resin transformers are also ideal for installations in tight spaces, where optimizing available volumes is essential. Moreover, their ability to withstand temperature variations, 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 railway systems, resin power transformers ensure superior energy quality, contributing to improved efficiency and stability of the electrical system as a whole.
