Metal-enclosed prefabricated substation
The box of this series of prefabricated substations is mainly composed of the base, side panels, partitions, doors and top covers, etc. The box is divided into the high-voltage room, the transformer room and the low-voltage room. The protection class of the transformer room is IP23. The sealing plates, partitions, doors and top covers above the base are made of cold-rolled steel plates and are connected together by welding or fasteners, which have sufficient mechanical strength. The inner and outer surfaces of all components of the box have undergone spraying treatment to form a durable protective layer.
