The box transformer substations in China were initially developed from the European-style box transformer substations, and they are often rlatively bulky in size.
With the opening of China's foreign economy and the vigorous development of the market economy,around the 1990s, the American COOPER Company took the lead in introducing American-style box transformer substations into the Chinese market,and they achieved rapid development in the Chinese market with their unique characteristics.
From south to north and from east to west in China, the American-style box transformer substations can be seen almost everywhere, and most of them are products copied by domestic manufacturers, and the quality of these products can be said to vary widely.
Through years of application and practice, it is necessary to conduct a serious analysis ofthe American-style box transformer substations in combination with China's national conditions, and give them a correct positioning, so as to promote the technological and market development of box transformer substations in China.
