step down transformer

Step down transformer Our company uses high-quality materials and advanced technologies, producing SG series of single & three-phase dry transformer between 0.5KVA to 500KVA. We have developed new transformers for import equipments according to the same kind of products of SIEMENS company, our products are fit for VDE0550, IEC439, JB5555, GB5226 national and international standards. SG series of three-phase dry transformer are widely used in the situation of 50 60Hz, the input and output voltage within 500V. The requirements of input/output voltage, coupling group, tapping adjustment, winding capacity allocation, with or without shell are all up to customers.
