3 phase 450v to 220v step down transformer

Brief Introduction

a. 3 phase dry type transformer is one of our mature products, which are manufactured in accordance with international and domestic market applications.

b. It is an energ saving electrical transformer which can convert the voltage as required, its ordinary power range starts from 300VA to 600KVA.  

c. 3 phase dry type transformer is ideal AC stabilized voltage supply for various industries, such as telecommunications, textiles, railways, schools, hospitals, hotels, national defense, scientific research, precision machine tools, and so on. Meanwhile, this dry type transformer is also applicable for low voltage power distribution when the available power supply coming with low voltage and wide fluctuation range.

Advantages and Functions

a. Using high quality new cold rolled silicon steel sheet, thickness 0.3 or 0.35mm ;

b.  H grade 180°heat-resistant enameled copper wire;

c. Energy saving and low noise coil have ventilation slots to make the air free flow and effectively reduce the coil temperature ;

d. Vacuum varnished and oven dried effectively reduce vibration and noise when running ,also increase the intensity of electric;

e. Terminal Blocks adopt foreign Well-known Brands, with excellent performance of compression , heat and flame resistance;
