American Style Box-type Substation
Our company, Yangzhou Huading Electric Co., Ltd., stands at the forefront of innovation with our state-of-the-art technology, having masterfully crafted the ZGS, ZFS, ZGSH, and ZFSH series of American-style box substations. Specifically engineered for optimal operation within 10kV and 20kV grid systems, these transformers are designed with a fully insulated structure, effectively eliminating any requirement for insulation distance and thereby ensuring unmatched personnel safety. Embracing a Dyn11 connection configuration, our transformers present extraordinary advantages, including superior voltage quality, a stable neutral point that remains unaffected by drift, and an exceptionally low noise level. These top-tier products find their applications in a diverse range of environments, from bustling factories and vibrant streets to residential communities, towering buildings, and commercial hubs. Their versatile nature allows for seamless adaptability to both ring networks and terminal connections, thereby simplifying the conversion process and significantly boosting the reliability of power supply.




Structural Features
Our cutting-edge American-style box transformer, tailored for photovoltaic and wind power new energy generation, boasts oil-immersed high-voltage load break switches and high-voltage fuses, ingeniously submerged in transformer oil. This innovative design results in a remarkably compact size and minimizes spatial footprint. The exposed transformer oil tank enhances heat dissipation capabilities, offers robust overload capacity, and ensures a high level of sealing and protection. The enclosure is crafted to provide exceptional mechanical strength, effectively resisting deformation during transportation and installation. Its appearance harmoniously blends with the
environment. The meticulously applied external coating guarantees resilience against sunlight, corrosion, and relentless sandstorms while ensuring strong adhesion. Meeting the IP54 standard, the product's protection level is unparalleled.
