Indoor box structure (protection grade IP30) distribution box frame is made of cold-rolled steel plate bent and welded. After spraying process treatment, anti - corrosion performance is good. The internal beams and plates are galvanized and passivated by aluminum-zinc coated plates or cold-rolled steel plates. The inside edge of the door with single side foamed glue, which can prevent the door from directly colliding with the box body, and also improve the protection grade of the door.
Outdoor box structure (protection grade IP65) Distribution box frame is made of stainless steel plate bent and welded. After outdoor spraying process treatment, with good corrosion resistance. The internal beams and plates are galvanized and passivated by aluminum-zinc coated plates or cold-rolled steel plates. The inside edge of the door with single side foamed glue, which can prevent the door from directly colliding with the box body, and also improve the protection grade of the door. If there are secondary components on the panel, the structure of the double door is adopted. The outer door is a glass door. The secondary components are installed on the inner door, the operating state of the device can be observed without opening the outer door.
