High overload distribution transformers
Product overview
In recent years, with the increasing mobility of the population, the hot season, and distribution transformers in rural areas during the Spring Festival period of severe overload short run problem of rural electricity appears. In order to solve such problem of electricity, the company response to the State Grid Corporation of China in recent years advocated actively develop rural power distribution transformers and high overload capacity application work, we developed a high overload capacity distribution transformers.
High overload capacity integrated rural power distribution transformer station area based on typical load characteristics, high overload distribution transformer overload performance will meet the 1.5 times the rated capacity of six hours, 1.75 times the rated capacity of 3 hours, 2.0 times the rated capacity of one hour of continuous operation stage design requirements, and does not affect the normal life of theCertifications
