IEEE/CSA Standard Three Phase Two Winding Oil Immersed 7 mva power Distribution Transformer Price 11kv 415v
Introduction of products
The performance of our SZ-M series,SZ series 10kV and 35kv load-ratio voltage transformer conform to the standard of IEC"Power transformer"and IEC60076 "Technical Parameters and Requirements of Three-phase Oil-immersed Power Transformer".The iron core is made of quality cold-rolled silicon steel sheet,and in full-miter non-puncture structure and the coil is made of quality oxygen-free copper,featuring good outlook and safe running.The product are widely used in power transmission and distribution of industrial and agricultural power networks.
Main functions and features
1 Load-ratio voltage regulation,high reliability,advanced level of performance,reasonable economical indicators.
2 The core joints are of stepped shape with 3 steps,and the surface of the core is coated with cured paint to lower losses and noise.
3 The winding has novel structure and its oil passage is reasonable designed.Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability.
4 The oil tank is in two types-fully enclosed type and the type fitted with an oil conservator.
