Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of oil immersed rectifier transformer in China. If you're going to wholesale durable oil immersed rectifier transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
An oil-immersed rectifier transformer is a special-purpose industrial transformer designed to match rectifier units. It converts grid alternating current into regulated AC voltage for diode or thyristor rectifiers, which then produce direct current for heavy industrial loads. Immersed in insulating mineral oil, it achieves reliable cooling and insulation. It is specially engineered to cope with harmonics, DC bias and non-sinusoidal currents generated during rectification, which standard distribution transformers cannot handle safely. Oil immersed rectifier transformer is mainly used in electrochemical industry( an industry using rectifier transformer mostly),traction with direct current power supply, transmission with direct current power supply and other fields.
Product parameters
Core Features
1.Support multi-pulse configurations (6-pulse, 12-pulse, 24-pulse) to reduce grid harmonic pollution
2.Reinforced winding construction and optimized magnetic circuit to avoid core saturation
Built-in higher impedance to limit short-circuit current
3.Oil cooling ensures stable performance under continuous heavy-duty operation
The oil-immersed rectifier transformer ensures stable electrical performance with a safety factor ≥1.67. Its robust windings offer high dynamic stability, with impedance 30% higher than ordinary power transformers to safeguard rectifier parts. Optimized thermal design keeps temperature rise below standard limits. Copper coils support reliable operation under rated loads and 110% overvoltage, with strong overload resistance. It features low no-load current, excellent energy efficiency and noise below 65dB. The streamlined structure adopts leak-proof oil tank technology to avoid oil leakage.
