The S11 series fully-sealed oil-immersed transformer was the primary choice for distribution equipment at the time, offering significant energy-saving performance. The product features high temperature resistance and impact resistance. Its integral tank, constructed with corrugated radiators, undergoes phosphating treatment and multi-layer anti-corrosion coating, ensuring excellent weatherability.
Product Details
This 250 KVA distribution transformer was delivered to china in 2020. the rated power of the transformer is 250 KVA. the primary voltage of the transformer is 11 KV and secondary is 400 V. We use high quality mineral oil and radiators, make the heat dissipation effect better. Our 250 KVA transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
The three-phase oil-immersed transformer applies new type insulation structure and improves the ability of short-circuit resistance. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made of high-quality copper wires and it adopts multilayer cylindrical structure. All fasteners have been processed with special treatment to prevent them from loosening.
yingben ensure each one of our delivered transformers had passed the full acceptance test and we remains 0 fault rate record for more than 10 years so far, our oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.
