SG Three-phase transformer
E04 series three-phase transformer is in reference to the internationally similar products, combined with China’s national conditions, based on development and production of a new generation of energy-saving transformers from 10KV A to 2000KVA, which refer to IEC439, GB5226, and other international and national standards, winding bodiless entire column using the winding method; transformer vacuum impregnation, the transformer insulation class F or product performance has reached the international advanced level. E04 series three-phase transformers are widely
used in AC 50Hz/60Hz, less than 660V voltage circuit is widely used in imported machinery and equipment, precision machine tools, machinery and electronic equipment, CNC machine tools, machining centers, lighting, etc. The products of the various input and output voltage, join groups, regulating tap winding capacity, and more distribution of the secondary winding of the equipment, the use of the circuit, can be based on user demands meticulous design and manufacturing.

Isolated output, safe and reliable, good anti-jamming, the isolation transformer to create a new line – grounding grid can relieve common-mode interference and other midline distress, isolation transformer will convert three-wire four wire connection A Yo system, plus shield on further exempt from the internal transformer-coupled high-frequency pulse interference and noise, although shielded isolation transformer for various NG interference (pulse and high-frequency noise) can effectively prevent, the transformer must be correctly and properly grounded, very strict,
otherwise, anti-there will be no common-mode interference effect, highly segregated, NG, good performance, high common-mode interference suppression will convert to Y or Y A to A, voltage taps easy to convert, according to the user’s specific performance requirements and design, the company can provide customers design and production high isolation transformer.
