ZDG-30/0.4 rectifier transformerDetailed product description：

1、 Product Description
ZDG-30/0.4 rectifier transformer is a type of transformer that converts the power supply of the power grid into the power required by the rectifier device. The transformer is divided into single-phase and three-phase series. The rectifier transformer is widely used in frequency conversion, electrochemical electrolysis, traction, transmission, DC transmission, electroplating, charging, excitation, electrostatic precipitator, and general industrial rectifier power supply.

2、 Product Features
1. ZDG-30/0.4 rectifier transformer is suitable for AC 50/60Hz and working voltage below 1600V. The insulation and heat resistance level of this series of rectifier transformers is F level;
2. The iron core of this product is made by stacking high-quality cold-rolled oriented silicon steel sheets, and the coil structure adopts cylindrical, elliptical, and rectangular cylinder types. Small size, excellent performance, safe and reliable;
3. The product is produced in accordance with the national standard GB/T18494.1-2001 or the Ministry of Machinery standards JB/T8636-1997 and JB/T2931-1999.
