ZHS Series oil-immersed rectifier transformer

Product description

They are widely used in electrolysis, electrochemical,driving,traction,static de-dusting,DC power transmission fields where rectification power source is necessary. A rectifier transformer is used for power supply of rectifying devices,most industrial DC power sources is transformed from an AC network via rectifier devices consisting of a rectifier transformer and a rectifier . It is widely used in electrolysis, electrochemical,traction ,driving,DC transmission,frequency conversion and rectified power source fields. According to user's requirements, the secondary winding phase difference can be designed to 30°，15°，7.5°，for rectification of 6-phase,12-phase, 24-phase and 48-phase.
