YBM box substation-European box transformer
Product characteristics
- European substation is composed of high voltage switch cabinet, mortgage distribution panel, distribution transformer and shell. High voltage is air load switch; transformer is dry transformer or oil-immersed transformer. The box adopts a good heat insulation ventilation structure, beautiful appearance, good heat insulation performance, and the box is equipped with the upper and lower ventilation air duct, the temperature rise caused by the outdoor solar radiation to the transformer room can be reduced to the minimum. The box can be equipped with temperature control forced ventilation device and automatic temperature control device. Each individual unit is equipped with perfect control, protection, live display and lighting systems.
