Description
Product description
Our S9, S10, S11 series 20KV, 35KV 3-phase oil-immersed transformer is 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. 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 type is various and good-looking.
