SGSBK, SG-F, JBK, BK, DBK, DK, JMB, JBKZ, BKC, DG series, three / phase dry transformer isolation is the factory in the light of the international similar products, combining with China's national conditions on the development of a new generation of energy-saving power transformer production, from 100VA to 1000KVA, in accordance with the national standard IEC439 and GB5226 international, with the entire column, winding bodiless winding method; transformer vacuum impregnation, the transformer insulation grade F or H grade, product performance to meet domestic and international advanced level. Transformer series single phase, three-phase dry isolation transformer is widely used in AC 50Hz to 60Hz, voltage The circuit below 1000V is widely used in import of important equipment, precision machine tools, mechanical and electronic equipment, medical equipment, rectifier, lighting factory, industrial and mining enterprises, stations, docks, airports, etc.. Products of various input and output voltage level, connected groups, adjusting the number and location of taps (typically + 5%), winding capacity allocation, single-phase secondary winding equipment, rectifier circuits used, whether with housing, can carry out meticulous design and manufacturing according to the requirements of users.

+Product features

The establishment of a new middle ground you can lift the common mode interference grid and other problems in the midline of the isolation transformer, transformer isolation three line delta connection into a four line Yo system, and further eliminates the shielding interference and noise by high frequency pulse transformer coupling, although the disturbance isolation transformer with shielding of N-G the (pulse and high frequency noise) can effectively prevent, but the transformer must be properly grounded properly, very strict, otherwise it will have no effect against common mode interference. The company can design and produce high quality isolation transformer for customers.

+Characteristic advantages:

ØHigh isolation

Ø N-GGood performance

ØHigh common mode interference suppression

ØThe conversion of Y or Y to Delta

ØVoltage tap is easy to convert

ØDesign according to user's special performance requirements
