With a new round of sustained and rapid economic growth, the electricity load demand is also growing rapidly, in order to improve the convenience, flexibility and reliability of the power outage of electricity use, the development of low voltage distribution cabinet and the application of more and more important. Low voltage distribution cabinet divided by function: Incoming Cabinet outlet cabinet, the contact cabinets, feeder panel, metering cabinet, reactive power compensation cabinet. The wide field of low-voltage electrical technology involved, the more sensitive to the development of new technologies. The development and application of many new technologies will drive the development of low-voltage electrical. Fieldbus technology development and application of low voltage distribution, control systems, and complete sets of equipment has also been new developments, including the compact, intelligent, can the new technologies of communication, high protection, high reliability, modularity, environmental protection, etc. characteristics. Low voltage distribution cabinet by virtue of these advantages are recognized by the people.GGD AC distribution cabinet is
