For power application scenarios requiring high safety levels and strict environmental standards, Jiangsu Hualai Electrical Technology Co., Ltd. specializes in the R&D, production and international trade of dry-type transformers, providing global clients with safe, stable and environmentally friendly complete power solutions. Different from traditional oil-immersed transformers, dry-type transformers adopt no liquid insulating medium, fundamentally eliminating risks of oil leakage, fire hazards and environmental pollution. They fully meet high-standard safety and environmental protection requirements, ensuring dual safety of equipment operation and site environment.
Our dry-type transformers are divided into two mainstream series: Cast Resin Transformer (CRT) and Vacuum Pressure Impregnated (VPI), accurately matching diverse working condition demands. CRT transformers feature high mechanical strength, excellent short-circuit resistance, and superior moisture and corrosion resistance, suitable for humid and corrosive environments. VPI transformers own high insulation heat resistance and outstanding flame retardant performance, producing no dense smoke under high-temperature conditions, which meets strict fire protection standards. All products adopt optimized magnetic circuit design to reduce eddy current loss, improve operational efficiency, save energy and extend service life.
This series of transformers has the advantages of low noise, light weight, compact structure and convenient installation. They are widely used in high-rise buildings, underground comprehensive facilities, airports, rail transit, data centers, commercial complexes and other densely populated and fire-sensitive scenarios, as well as industrial sites such as power plants and nuclear power plants where oil-immersed equipment is prohibited. Equipped with an intelligent temperature monitoring and protection system, the transformers can real-timely monitor winding temperature, automatically start and stop heat dissipation devices, and trigger alarm and tripping protection in case of overheating abnormalities, realizing automatic safety protection and long-term stable system operation.
Equipped with advanced automated production equipment and a professional R&D team, we mass-produce full-specification dry-type transformers ranging from 10kVA to 2500kVA, fully meeting the procurement demands of civil, industrial and special power projects. Manufactured in strict accordance with international industry standards and certified by multiple international authoritative institutions, our products adapt to project acceptance and import & export trade requirements worldwide, winning wide recognition from global customers for stable performance and high reliability.
Jiangsu Hualai’s dry-type transformers fully meet the demands of high-safety and green power construction. With mature technical accumulation and standardized production systems, we provide global customers with reliable power equipment and professional solutions, serving as a high-quality and trustworthy supplier in the industry.
