Phase-Shifting Rectifier Transformer
09-03 2024 | By:
Rectifier transformer is a transformer specially used for rectifier system. Its function is to supply proper voltage to rectifier system and reduce the pollution to power grid caused by waveform distortion caused by rectifier system. It is widely used in lighting, machine tool electrical appliances, mechanical and electronic equipment, electric locomotive, medical equipment, rectifier device, etc. The product performance can meet various special requirements of users.
Using C-class DuPont insulation material, it has strong overload and fireproof capabilities
Excellent structure, small size, low noise, winding with the same mode, high mechanical strength, strong short-circuit resistance, safe and reliable operation
Advanced insulation structure, the secondary side can reach up to 27 phase windings, reducing the impact of system harmonics on the power grid and other equipment
Factory test
ZTELECGROUP can prepare and issue a test report for each transformer in accordance with IEC 60076. In addition to routine tests, we also provide type tests and special tests to meet all customer requirements.
