Intelligent high protection electrical meter box, which material is new type environment friendly engineering polycarbonate plastic (PC), has performance of high insulation, transparent, X-ray resistant, age resistant, acid rain resistant, slat fog resistant, low temperature resistant and shocking resistant, and also good ventilated, rain proof and heat dissipation. Service lift is above 30 years.
It is with integrated design idea, making all types electrical meters and whole metering loop into one box. It can not only be installed in small space, but also prevent electricity stolen and metering device.
It is easy for installation with bolts at back, which is attached on the concrete surface closely. The cover is locked with box by pothook, dedicated screw and padlock. Only managing people can open it with spanner and key. People can see any the abnormal inside the box without open it to work out the hidden danger in advanced, which can realize the aim of safe using electricity and prevention.
