Compared with the simple design of the American-style box transformer substation,the YBW European-style box transformer substation appears stable and generous, and it pays more attention to the combination of tradition and innovation.
It originated in countries such as France and Germany, and began to be widely used in China in the late 1970s.
The European-style box transformer substation is composed of parts such as transformers, high-voltage switchgear, and low-voltage switchgear. Each device is closely connected by cables or other transmission media to form an efficient and stable power system.
It adopts the layout of the "mu" shape or the "pin" shape structure.
The box is not only equipped with conventional medium-voltage switchgear/ring main units and low-voltage boxes, but also installed with transformers, making the product relatively large in volume.
