What Are The Variations In Waterproof Junction Boxes Made Of Polycarbonate?

Polycarbonate (PC), as a thermoplastic polymer material, is widely used in the manufacture of electrical sealing housings for waterproof junction box, especially suitable for wiring systems in outdoor or moisture-prone areas. PC material has excellent impact resistance and weather resistance, characteristics that cannot be easily replaced by die-cast metals or other engineering plastics, providing higher mechanical strength and durability support for waterproof distribution box.

During the waterproof electrical box design phase, the fit between the housing and cover, the configuration of the sealing components, and the mechanical design of the cable entry point all need to meet industry protection level standards (such as IP65, IP66, IP68, etc.) in order to meet the environmental requirements of various usage scenarios. These protection rating standards represent test parameters for liquid and solid intrusion, providing a basis for verifying the performance of the outdoor junction box under conditions of rain splash, humid air, or short-term immersion.
