Why should distribution boxes be dustproof
Therefore, in order to ensure the normal operation of the equipment and prolong the service life, the distribution box needs to take dust-proof measures. Common dust prevention measures include: installing gaskets, dust covers, fans, etc. In addition, dust will also reduce the heat dissipation efficiency of the distribution box. However, the outdoor environment is complex and changeable, and extreme weather, sandstorms and other phenomena often occur, which requires metal distribution boxes to have good waterproof and dustproof performance to ensure the stable operation of the power system.
