Henan Heshan Electric Co., Ltd. is committed to providing leading dry-type transformer products to global customers. Our 11kV and 33kV dry-type transformer series are designed specifically for medium-voltage power distribution systems.
With their superior oil-free fire-resistant properties, excellent energy efficiency, and outstanding environmental adaptability, they have become a safe and reliable core choice in modern power infrastructure.
Ultimate safety, worry-free fire protection: Utilizing high-strength epoxy resin fully encapsulated windings formed by vacuum casting, it possesses excellent flame-retardant and explosion-proof properties, eliminating any risk of combustion or explosion. It eliminates potential oil leakage and fire hazards from the source, making it an ideal choice for high-rise buildings, underground substations, data centers, densely populated areas, and environments with extremely high fire protection requirements.
Green and environmentally friendly, maintenance-free operation: The transformer has no insulating oil, no emissions of toxic substances, and no risk of soil pollution, truly achieving green and environmentally friendly operation. The fully enclosed structure is moisture-proof, dust-proof, and corrosion-proof, requiring no daily maintenance and significantly reducing the total life cycle maintenance cost.
High efficiency and energy saving, economical and reliable: The iron core is made of high-permeability, low-loss high-quality cold-rolled oriented silicon steel sheets, and uses an advanced seven-step 45-degree full oblique joint process. The no-load loss is reduced by 3-5% compared with the traditional three-step process, effectively reducing the energy consumption of the power grid and helping users achieve energy saving and carbon reduction goals.
Exquisite craftsmanship, transparent quality: We insist on making our processes visible. In the core iron core manufacturing, we employ a unique transparent insulating varnish treatment technology, making the internal materials and process details readily apparent, demonstrating our absolute confidence in our materials and craftsmanship. Combined with a specially designed iron core bending fixture, we ensure iron core assembly precision, significantly reduce operating noise, and provide a quieter electrical environment.
