Transformer voltage is not the same

China's rapid economic development in recent years, the national economy has also developed and powerful. More and more people go out of the country, more and more enterprises to seek foreign development, and constantly develop foreign trade business. Transformer industry is no exception. General transformer exports have some 100kva single phase pole mounted transformer, such as export-specific transformers. Because the voltage standards vary from country to country. The United States and other countries with 120V voltage, electrical protection focus is on fire; and for China and other countries with 220V voltage, electrical protection focus is on electric shock from a theoretical point of view, the higher the voltage, the smaller the loss on the line, The lower the voltage the more secure. So the transformer in the direction of the export we also need to pay attention to its voltage use of the different. Whether small and medium enterprises of the pressure device manufacturers, or large transformer factory. Transformer exports have become part of the daily processing of production. This kind of transformer to provide regulated voltage for the power grid also plays an important role in the daily power grid.
