Generally, the quality of the Electronic Enclosure is mainly determined by the material, surface treatment and IP level.
The Electronic Enclosure is generally required to use standard cold-rolled plate. The thickness is 1.2~2.0mm, of which the switch box body steel plate thickness shall not be less than 1.2mm, and the distribution box body steel plate thickness shall not be less than 1.5mm. The box door shall be equipped with reinforcement ribs, and the box surface shall be treated with anti-corrosion.
The IP protection level of the distribution box is based on GB/T4942.2-93 "Protection Level of Low-voltage Electrical Appliance Shell". According to different distribution box application technical requirements, select distribution boxes with different IP protection levels. The appearance structure of the distribution box and switch box should be rainproof and dustproof. The protection level shall not be lower than IP21 when the door is open, and shall not be lower than IP44 when the door is closed.
The surface treatment of the distribution box generally depends on whether the welding and grinding surface is flat, whether the spraying surface is smooth, and whether the color is uniform and free of particles.
