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 urban power grids, commercial centers, airports, tunnels, stations, harbors, high-rise buildings, hospitals, and theaters, it can also be matched with modular substation sets.

2. Coils are wound with copper wire or foil, reinforced with glass fiber, and vacuum dried degassed and dewaxed with no fillers added to the epoxy resin, featuring high mechanical strength, excellent short-circuit resistance, and strong impact resistance.

3. The core is made of high-quality grain-oriented cold-rolled silicon steel sheets, assembled with 45° full diagonal joints and stepwise stacking method, effectively reducing no-load losses and product noise.

4. The core, coil, and clamping pieces are secured using elastic elements, ensuring the coil remains in a stable state to reduce product noise.

5. The inner wall of the overall cast high and low voltage coil tube is provided with longitudinal ventilation channels, which can be equipped with a forced air cooling unit. After the installation of the forced air cooling unit, 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 features fault alarm, over-temperature alarm, and over-temperature trip functions. Provides reliable overload protection for dry-type transformers, thereby enhancing the operational safety of dry-type transformers.
