D11 single-phase oil-immersed transformer

Western developed countries and Southeast Asia, North and South America, a large number of single-phase transformers are used as distribution transformers. In the power distribution network, single-phase transformer has great advantages as a distribution transformer. It can reduce the length of low-voltage distribution lines, reduce line losses, improve power supply quality, and adopt high-efficiency and energy-saving coil core structure design. The transformer is characterized by adopting Du-upper suspension installation method, small volume, small capital construction investment, reducing low-voltage power supply radius, reducing low-voltage line losses by more than 60%. The transformer adopts fully sealed structure, strong overload capacity, high continuous operation reliability and simple maintenance, long service life.
