According to the increasing demand for electricity, the development trend of the distribution transformer industry is improving. As the demand for electricity increases, the demand for distribution transformers also increases. As one of the important equipment in the power transmission and distribution system, distribution transformers can reduce the voltage from 6-10 kV to around 400 V before inputting it to users. Their installation scenarios are generally on poles or in distribution stations. With the advancement of technology, distribution transformers themselves have become more advanced. In recent years, with the vigorous promotion of multiple power construction projects (such as smart grids), the development trend of the distribution transformer market has improved. The Chinese government is also supporting and encouraging the development of the power industry. This will have a positive impact on the development of the distribution transformer industry.
