1，表箱上盖透明部分使用进口聚碳酸酯(PC)，由于PC具有比较全面的平衡性能、优良的耐冲击性、稳定性、透光率达到90%以上，再配以我公司特有的辅料，从而保证具有耐老化、抗冲击、抗紫外线、耐酸雨盐雾、阻燃、耐热、抗冻、绝缘性高。

1, the meter box cover part of the use of imported transparent polycarbonate (PC), because PC has a more comprehensive balance of performance, excellent impact resistance, stability, light transmission rate of more than 90%, with our unique accessories, which has anti-aging, anti shock, anti UV, acid rain and salt fog flame retardant and heat resistance, frost resistance, high insulation resistance.

2，低壳部分采用进口聚碳酸酯(PC)和改性ABS工程塑料新料，我公司专门研发了由PC70%+ABS30%组成的混合合金材料。该材料硬度高，耐老化性能极佳，产品不褪色使用寿命长。适用于高温环境，遇到高温或火灾时，该材料不但不燃烧，而且能阻止燃烧。热变形温度为130℃，能承受零下50℃的低温，阻燃性能为FV0级，抗冲击性能为1K10级。绝缘性高，在工频2000V试验电压下不发生飞弧、击穿、闪络现象，特别适用于电力行业。

2, the low shell part adopts imported polycarbonate (PC) and modified ABS engineering plastic new material. Our company specially developed the mixed alloy material composed of PC70%+ABS30%. The material has high hardness, excellent aging resistance, long service life and long service life. It is suitable for high temperature environment. When it encounters high temperature or fire, the material not only does not burn, but also prevents combustion. The thermal deformation temperature is 130 degrees, and can withstand subzero temperature of 50 degrees centigrade. The flame retardancy is FV0, and the impact resistance is 1K10. High insulation, no arcing, breakdown and flashover in the power frequency 2000V test voltage, especially suitable for the power industry.

3，因此上述两种材料具有强度高、抗老化、绝缘性强、透明度好、抗紫外线、耐酸雨盐雾、抗弯曲、抗冲击、耐热、抗冻，特别适用于户外，正常使用寿命可达30年以上。

3, so the above two kinds of materials with high strength, aging resistance, insulation resistance, good transparency, anti UV, acid rain and salt fog, bending, impact resistance, heat resistance, frost resistance, especially suitable for outdoor, the normal service life of up to 30 years.
