This series of epoxy-encapsulated transformers is manufactured using advanced technology, ensuring high reliability and long service life. Protective enclosures can be added according to different protection levels. Suitable for key locations such as urban power grids, commercial centers, airports, tunnels, stations, docks, high-rise buildings, hospitals, and theaters, and can be matched with modular substation systems.

2. Coils are wound with copper wire or foil, reinforced with glass fiber, and vacuum dried degassed and dehumidified with epoxy resin without fillers for overall casting, featuring high mechanical strength, excellent short-circuit resistance, and strong shock resistance.

3. Core made of high-quality grain-oriented cold-rolled silicon steel sheets, with 45° full diagonal joints and stepped lamination method, effectively reducing no-load losses and product noise.

4. The core, coil, and clamp are secured with elastic components, ensuring the coil remains stable to reduce product noise.

5. The internal wall of the overall cast high and low voltage coil tube is pre-drilled with longitudinal ventilation channels, which can be equipped with a forced air cooling system. After the installation of the forced air cooling system, the rated output capacity can be increased.

6. Equipped with a winding temperature controller to monitor transformer winding temperature rise, automatically start/stop cooling fans, and feature fault alarms, over-temperature alarms, and over-temperature tripping functions. Provides reliable overload protection for dry-type transformers, thereby enhancing the safety of their operation.
