Jiangsu Hualai Electrical Technology Co., Ltd. specializes in the R&D, production, and export of dry-type transformers, offering safe, efficient, and eco-friendly power solutions for global customers. Unlike traditional oil-immersed transformers, our dry-type transformers do not use liquid insulating media, eliminating the risk of oil leakage, fire, and environmental pollution, making them ideal for locations with strict safety and environmental requirements.
Our dry-type transformers are mainly divided into two categories: epoxy resin cast (CRT) and vacuum pressure impregnated (VPI) types. The epoxy resin cast transformers have high mechanical strength, strong short-circuit resistance, good moisture and corrosion resistance, while the VPI transformers feature high insulation heat resistance and better fire performance, producing no heavy smoke when burned at high temperatures. All our dry-type transformers adopt optimized magnetic circuit design, reducing eddy current losses and improving overall efficiency.
With the advantages of low noise, small size, light weight, and easy installation, our dry-type transformers are widely used in high-rise buildings, underground facilities, airports, theaters, subway stations, data centers, commercial centers, and other densely populated or fire-sensitive areas. They can also be used in power plants, nuclear power plants, and other industrial sites where oil-immersed transformers are not suitable. The transformers are equipped with a complete intelligent temperature monitoring and protection system, which can automatically detect winding temperature, start/stop fans, and issue alarms or trip signals when overheating occurs, ensuring safe and stable operation.
As a leading manufacturer in China’s dry-type transformer industry, Jiangsu Hualai has advanced production equipment and a professional R&D team, capable of producing transformers with a capacity range of 10kVA to 2500kVA, meeting the diverse needs of customers worldwide. Our products comply with international standards and have passed relevant certifications, ensuring smooth customs clearance and reliable performance in global markets.
