Rectifier transformer

Rectifier transformer

Transformer working for medium frequency induction furnace, electric arc furnace, continuous casting machine, rolling mill steel plant.

The S9, S10, S11 series of 20kV and 35kV three-phase oil-immersed rectifier transformers produced by our company meet the requirements of CE, UL, CSA, ROUSH, GB1094 "Power Transformer" and GB / T6451-2008 "Three-Phase Oil Immersed Power Transformer technical parameters and requirements "standard. The core is made of high-quality cold-rolled silicon steel sheet, and the coil is made of high-quality oxygen-free copper, which is beautiful in appearance and safe in operation. Widely used in steel mills, urban and rural industrial and agricultural power grids.

Main functions and features:

◎ High reliability, advanced performance level and reasonable economic indicators.

◎ The iron core adopts step-shaped three-level joints, and the surface is painted with cured paint to reduce loss and noise.

◎ New winding structure, reasonable oil channel design, and new insulation structure to improve mechanical strength and short circuit resistance.

◎ The fuel tank has various forms, beautiful and generous.

220kV, 110kV and 66kV low loss series transformers; products with reliable performance, low partial discharge, low loss, low noise, high reliability, and strong resistance to sudden short circuit, its excellent performance has won the majority of users and related Experts highly praise.
