In order to ensure the waterproof performance of distribution boxes, manufacturers will strictly seal the joints of the box. Usually, rubber sealing rings or sealants are used for sealing to effectively prevent the intrusion of rainwater, sand and dust. It is generally used outdoors, and it is a very good rainproof equipment. Rainproof distribution box shell welding processing, and in the process of its shell processing, after the surface of high-voltage electrostatic. waterproof junction box is very common in industrial manufacturing due to its light weight, high strength and good thermal conductivity. The prerequisite for the exact application of sealing. At present, the common heat dissipation method of the distribution box is to open cooling holes on the box body, and use natural ventilation to achieve heat exchange.
