The dry-type transformer uses epoxy resin vacuum casting for high-voltage windings and copper foil or wire for low-voltage windings, with the core and windings directly exposed to air and cooled by natural convection or forced air. Without any flammable liquid, it is inherently fireproof and explosion-proof, with no oil leakage, making it ideal for crowded or environmentally sensitive areas. Insulation levels reach Class F or H, and a standard digital temperature controller with automatic fan cooling monitors temperature and controls fans. It features low partial discharge and low noise below 45 decibels. Key applications include high-rise buildings, commercial complexes, hospitals, schools, data centers, subway stations, and underground substations. Compared to oil-immersed units, dry-type transformers can be installed near the load center, significantly reducing low-voltage cable length, line losses, and installation costs. Apart from periodic air duct cleaning, they require almost no maintenance. Although initial cost is slightly higher, their advantages in fire safety, environmental friendliness, and installation flexibility make them the preferred choice for urban distribution projects. We support customized configurations in capacity, insulation class, and protective enclosure.
