In non-metallic materials, fiber-reinforced polyester materials have excellent anti-aging properties. After anti-aging performance tests,it shows that the maximum aging thickness of the surface is less than 50μm in 20 years because of different using locations and climate zones. The minimum thickness of most boxes is 5mm, which is less than 1% of the box thickness and have no significant effect to the box mechanical properties. Low-voltage outdoor branch box adopts a special UV-resistant surface treatment process, which enhance its anti-aging properties. European using history shows that its service life is at least 20 years old. After simulated aging tests it show that its service life is more than 20 years, which exceeds more than the traditional materials such as metal.
Ventilation components are left in the box door, the lower end and the upper end of the backboard, the top board and between the box door and the backboard. With the heat generated by the electrical components, the inner space of box can be dehumidified to prevent the metal corrosion inside the box and leakage. For the cable branch box with base, through the base is filled with fine sand and buried under the surface of a certain depth, so that soil moisture does not rise into the box.
