As a Jiangsu private science and technology enterprise, our company, Taizhou Haitian Electric Manufacturing Co., Ltd., is honored as Jiangsu Green Factory, Taizhou Top Ten High-Growth Enterprise and Hailing District Top Ten Scientific and Technological Innovation Enterprise. Founded in 1958 as Taizhou Transformer Factory, our company was a designated power transformer manufacturer under the former relevant ministries and an associated unit of China State Shipbuilding Corporation. Now an accredited supplier of State Power Investment Corporation and China Southern Power Grid, our company has over 50 years of transformer manufacturing experience.
The oil-immersed on-load tap-changing distribution transformer adopts a high-quality laminated silicon steel core and oxygen-free copper windings with a stable structure and strong short-circuit resistance. Different from conventional oil-immersed distribution transformers, the oil-immersed on-load tap-changing distribution transformer is equipped with on-load tap changers. The transformer realises voltage regulation under load without a power cut, which can adapt to grid voltage fluctuations in real time and maintain high output voltage precision. The oil-immersed on-load tap-changing distribution transformer adopts a fully sealed corrugated oil tank and an oil-immersed self-cooling system. The transformer features excellent insulation performance, stable operation without oil leakage and convenient maintenance. The oil-immersed on-load tap-changing distribution transformer is widely applied to urban and rural power stations, industrial mines and park power supply with large grid voltage fluctuation and complex power load. The equipment achieves higher power supply quality, stronger power supply reliability and long service life.
