Shandong supply polycarbonate meter box, the PC meter box, plastic meter box, FRP meter box, power box, SMC meter box, meter box manufacturers, Shandong meter box, material characteristics: 1. Above the meter box transparent part of the use of imported polyethylene carbonate (PC), the PC has a more comprehensive balance performance, excellent impact resistance, stability, light transmittance of more than 90%, adding to the company-specific accessories, in order to ensure has anti-aging, shock, anti-UV, acid-rain salt spray, flame retardant, heat, frost insulation. Low shell part the import polycarbonate (PC) and modified ABS engineering plastics new material, my company specializes in research and development of a mixed alloy material from PC70% + ABS30%. The high material hardness, excellent performance of anti-aging products do not fade and long service life. Suitable for high temperature environments, high temperature or fire is encountered, the material not only does not burn, but also can prevent combustion. Heat distortion temperature of 130 ° C and can withstand low temperatures of minus 50 ℃, flame retardant properties FV0 level, impact resistance 1K10 level. High insulation, in the frequency 2000V test voltage arcing occurs, breakdown, flashover, especially suitable for the power industry. 3 of the two materials with high strength, anti-aging, insulation, good transparency, anti-UV, acid-rain salt spray, anti-bending, impact, heat, frost, especially suitable for the outdoors, the normal useful life of over 10 years. Product protection: company has fully passed the ISO9001 international quality management system certification, all products have passed 3C certification. With perfect design, high protection, high security, high flexibility popular end-user recognition of the power industry units, and then a number of projects in the meter box market trends. Quality products and good service received by customers of all ages. Third, the product scope of polycarbonate meter box consists of two parts of the single-phase meter box and three-phase meter box, is suitable for AC 50HZ or 60HZ, rated voltage to 200V, 380V, 693V, the amount of passenger operating current 10A ~ 225A The power supply system, for single-phase energy and power energy measurement and control management. Meter box conditions of use: 3 Ambient temperature -40 ° C to +80 ° C, and 24-hour average temperature does not exceed +35 ° C Air cleaner 4, the relative temperature at 40 ℃ does not exceed 80%, and allowed to have a higher relative temperature lower temperatures. Polycarbonate meter box installed using an installation carefully check the integrity of the various components of the meter box. 2 meter box should be mounted vertically, the angle of inclination. Shall be not more than 5 ° 3 installation location should choose non-violent vibration, impact, and not enough to corrode electrical components. Meter box lock material impatience strong bases, oxidizing acids and amines, ketones, the dissolved in oxidation diameter class and aromatic deep agent, so should avoid contact with these chemicals or used together. 5 should be avoided during use sharp objects and hard objects collide scratching the surface of the meter box 6 meter box installed should try to choose a cool, dry place, avoid the sun for a long time direct exposure to prolong the life of the energy meter.
