5400kVA 10kv 0.74kv Electrolyed Electro-Chemistry Rectifier Transformer
Product Description
Introduction:
The product is widely applied to the system of needing to supply rectifying power such as electrolytic
electrochemical, transmission,traction, electrostatic dust removal, dc transmission, etc. The rectiformer is use to
rectify device power.Most of the dc power used in industry is gotten from ac power grid through rectifying
device which is composed of the rectiformer and rectifier.It is widely applied to electrochemical electrolysis,
traction, transmission, dc power, inverter and general industrial rectifying power,etc.Designing
and manufacturing secondary winding whose phase difference is 30°,15° and 7.5° provide a variety of forms of
structuress products whose phase is 6, 12, 24 and 48 to rectify according to various of the needs of users.
