10kv level, SZ9-M, SZ10-M, SZ11-M series Series three-phase omni-sealed transformer with on-load tap changer

Product description

　　The performance of our SZ-M series, SZ series 10kv and 35kv load-ratio voltage transformer conform to the standard of IEC and GB1094 "Power Transformer" and GB/T6451-2008 "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. The coil is made of quality oxygen-free copper, featuring good outlook and safe running. The products are widely used in power transmission and distribution of industrial and agricultural power networks.

Feature

1. Load-ratio voltage regulation, high reliability, advanced level of performances,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.
