Our company uses high-quality materials and advanced technology, professional production of SG, DG series three-phase and single-phase isolation transformer, the series transformer transformer in the grid not only function, but also isolate the grid for the third harmonic devices life protection and machine-generated heat insulating material is reduced. Especially for imported equipment (380V feed → 220V out, 380V feed → any voltage output, 220V feed → any voltage output) specifications between 1KVA ~ 600KVA, SG, DG series dry-type isolation transformers are widely used in AC 50 ~ 60HZ, enter The output voltage does not exceed 500V three-phase supply various occasions. Product of the input and output voltage (single-phase, three-phase or multi-channel input and output, etc.), connection mode, adjust the wiper position, winding capacity allocation, with a secondary winding, the outer box (depending on the use environment selection), may be carefully designed and manufactured according to user requirements. Characteristic has a voltage conversion function (eg: △ / Yo or Yo / △ connection) with a filter anti-jamming function (eg: you can remove the third harmonic) has a heat resistance, moisture resistance, stability, chemical compatibility, low temperature resistance, radiation resistance and non-toxic environmentally friendly features.
