SG, SBK, SG-F, JBK, BK, DBK, DK, JMB, JBKZ, BKC, DG Series 3 / single-phase dry type isolation transformer factory in the light of the international similar products, based on the situation of China's development and production of new generation of energy-saving power transformers from 100VA to 1000KVA, which meets IEC439, GB5226 and other international, national standards, winding around the entire column with the way it emerged from the womb; transformer vacuum dipping, so that the transformer insulation class F or H grade to grade, the product performance to advanced level. Transformer single-phase, three phase dry type isolation transformers are widely used in AC 50Hz to 60Hz, voltage of 1000V the following circuit, widely used in the import key equipment, precision machine tools, machinery and electronic equipment, medical equipment, rectifiers, lighting factory; industrial and mining enterprises , stations, terminals and the airport. Of input and output voltage level, joint group and tap the number and location (typically ± 5%), winding capacity allocation, single-phase windings with the secondary, the use of rectifier circuit, is required with shell, etc., can be based on user demands meticulous design and manufacturing.
+ Features
      Isolation transformer in a new center line - you can lift the power ground common mode interference and other troubled middle, isolation transformer will be three-to four-wire conversion △ Yo wiring system, plus shielded from the transformer to further Mianchu the internal coupling of high-frequency pulse interference and noise, although shielded isolation transformer to the interference of various NG (pulse and high frequency noise) can effectively prevent, but the transformer must be correctly and properly grounded, very strict, otherwise the resistance will be no effect of common mode interference. The company can design and produce high-quality customer isolation transformer.
+ Feature advantages:
Ø a high degree of isolation
Ø N-G in good
Ø a high degree of common mode interference rejection
Ø will be converted to Y or △ △ Y to
Ø easy to convert voltage tap
Ø by the user's specific performance requirements Design

+ Technical indicators
1 Input Voltage: 380V or 380V single-phase or single phase 220V
2 Output Voltage: (based on customer request)
3 Operating frequency: 50Hz-60Hz
4 Efficiency: ≥ 95%
5 Temperature rise: <60
6 Waveform distortion: <0.1%
7 High Voltage Test: 2500V, 1 minutes at zero breakdown
8 Insulation resistance: winding to ground insulation resistance ≥ 500M Euro

+ Use
1 to altitude: ≤ 5000m
2 Ambient temperature: -15 ℃ ~ +45 ℃
3 Relative humidity: ≤ 90%
4 installation sites should not seriously affect the strength of transformer insulating gas, steam, chemical deposition, dirt, dust, and no other explosive conductive flammable corrosive substances.
5 who do not meet the above conditions of use shall be determined in consultation with us.
