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, 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.

Brief Description:
The products in this section are oil-immersed special transformer, used in three phase,50Hz,110kV and below 110kV power system, aremain power equipment in metallurgical industry,chemical industry, which transform power system voltage into multi-phase AC voltage thatrectifier need and change to DC power through rectifier for electrochemical, DECM, electroplate, excitation, traction,etc. the below mentionedequipment are mainly used in the field of Metal electrolytic (such as aluminum, manganese, copper,zinc,etc), chlor-alkali and graphitization,etc.
