MNS low-voltage drawer cabinet is favored by many power engineering customers for its advantages of convenient maintenance, many group outgoing circuits and small land occupation. Although there are many manufacturers in the field, the technology and production capacity are mixed. Many small and medium-sized switchgear plants do not master the specifications and standards related to the machinery and equipment in the power distribution room because of their weak technical foundation. There are risks in the design and installation of drawer cabinets and switchgear. In addition, the customer's operation and maintenance management is poor, and the components in the cabinets are aging slowly with the increase of operation time, It will cause a high incidence of accidents of high-voltage switchgear and even major accidents such as burning loss.
MNS low-voltage drawer type switchgear is applicable to the three-phase five wire power supply system with AC 50 (60) Hz, rated working voltage of 400V and 660V, rated current of 5000A and below. It can be used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks, radio and television and other communication points to control power generation, transmission and distribution, power conversion and power consumption equipment, The reactive power of the main bus is compensated through the capacitor compensation cabinet. Comply with national standards: gb7251.1 low voltage switchgear and iec60439 low voltage switchgear and control equipment.
