After many aging tests, it has been proved that the service life of FRP meter box can be more than 15 years, and its service life seems to exceed that of metal meter box. However, from the perspective of safety, the metal meter box is still safe. The test shows that the meter box is used in different places, and the weather is different. Its aging thickness is less than 50 in 20 years μ m。 The anti-aging performance of FRP meter box is really good.

FRP meter box is made of unsaturated polyester glass reinforced fiber molding. If the component is overloaded and the fiber breaks, the load will be quickly distributed on the undamaged fiber to re balance its mechanics. This material is a kind of fire-retardant material, and its fire-retardant grade is fv0 (the highest level of non-metallic materials). Under high temperature environment, the smoke level of the complete set of equipment is grade 15, and the smoke is non-toxic. Its outstanding performance is superior to the shortcomings of wooden and plastic meter boxes, such as easy aging, easy corrosion, poor insulation, poor frost resistance, poor flame retardancy and so on. The good performance of FRP meter box has good water resistance, corrosion resistance and electricity theft resistance. The service life can be more than 15 years outdoors and more than 20 years indoors

This product is mainly used in residential buildings, with more than 200 sets of modules. It can also be installed in the meter box, secondary protection, single switch, wiring terminal, external control switch of the meter box and other functions. It can be installed on the wall or on the electric pole, and the user can directly operate the switch outside the meter box. Fiber reinforced polyester material has good tensile strength, and the highest fatigue resistance can reach 70% - 80%.

Insulation protection and electricity theft prevention indicators meet relevant standards. Fiber reinforced polyester material has very good corrosion resistance to acid, dilute alkali, salt, organic solvents, etc. this material not only has good insulation, but also can maintain good dielectric energy at high frequency, and is not affected by electromagnetic action and does not reflect electromagnetic waves. Specific strength and specific modulus are one of the indicators to measure the bearing capacity of materials. The specific modulus of fiber-reinforced polyester is basically the same as that of steel
