Overview
Three-phase dry isolation transformer is the factory in reference to international similar products, combined with China's national conditions on the basis of the development and production of a new generation of energy-saving power transformers, from 100VA to 1600KVA between, in line with IEC439, GB5226 and other international and national standards, The whole winding method; transformer vacuum immersion paint, so that the transformer insulation class to F-class or H-class, product performance to the advanced level at home and abroad. Three-phase isolation transformer is widely used in AC 50Hz to 60Hz, voltage 1000V (1140V) the following circuit, widely used in the import of important equipment, precision machine tools, mechanical and electronic equipment, medical equipment, rectifier, lighting and so on. (Usually ± 5%), winding capacity distribution, secondary single-phase winding equipment, the use of rectifier circuit, whether the requirements of the belt, the number of input and output voltage, Shell, etc., can be based on user requirements for careful design and manufacturing.

Product features

In the isolation transformer to establish a new center line - ground can be removed from the grid in the common mode interference and other midline problems, the isolation transformer will be three-wire △ cable converted to four-wire Yo system, plus shielding to further remove the transformer coupling within the high-frequency pulse interference And noise, although the shielded isolation transformer for a variety of NG interference (pulse and high frequency noise) can effectively prevent, but the transformer must be properly properly grounded, very strict, otherwise the anti-common mode interference will be ineffective. The company can design and produce high-quality isolation transformer for customers.
