National Power Supply Bureau PC transparent meter box, FRP meter box, power box, measuring box, distribution box, meter box material, the price of the meter box, meter boxes offer PC transparent meter box, transparent design, transparent material is not only intuitive, but also timely discovery of the various anomalies in the meter box, advance to exclude security risks in the electricity, to really "safe use of electricity, prevention-oriented" management objectives. New environmentally friendly engineering plastics polycarbonate (PC), has high insulating properties, transparency, anti-UV, anti-aging, acid rain, salt spray, high temperature, low temperature, impact, performance, and good ventilation. rain, heat and other functions, the normal life of more than 30 years. Meter box with integrated design philosophy, the kinds of power meters and harmonious Marriage Law, the amount of loop sets installed in the integration of the closed box, and not only a small footprint, easy to install and manage, and be able to stop stealing hit a metering device to prevent stealing behavior. Meter cabinet is handsome in appearance, well-proportioned, smooth lines, can be easily reserved through the back of the bolt hole, firmly installed in the concrete wall. The compact component structure in the box, while the Bureau of reasonable, alignments, smooth and clear. Box cover by hooking the special screw interlock and padlock box, only electric tubes staff by special spanner and key before opening. Since the launch of the meter box, with its unique design, innovative technology and advanced performance, favored by a growing number of power supply enterprise. 1 Scope and conditions of use meter box including single-phase meter box and three-phase meter box two parts, is suitable for AC 50HZ or 60HZ, rated working voltage up to 200V, 380V, 693V, the amount of passenger operating current of 10A ~ 225A for electrical system, for single-phase energy and power energy measurement and control management. Conditions of Use: 3 Ambient temperature -40 ℃ ~ +80 ℃, and within 24 hours the average temperature does not exceed +35 ℃. Air cleaner 4, the relative temperature at 40 ℃ does not exceed 80%, and allowed to have a higher relative temperature lower temperatures. 5 Product 6 Main busbar rated current ln: 225A-10A main bus Rated short-time withstand current lcw: 30KA 8 Insulation resistance: not less than 20MΩ 9 Rated insulation voltage Ui: 800V 10 Frequency: 50HZ or 60HZ 11 security protection class IP: 30 12 product installation and use of 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.
