MNS low-voltage draw out switchgear is applicable to systems with AC 50 (60) Hz rated working voltage of 660V and below, and is used for power generation, transmission, distribution, power conversion and control of power consumption equipment. Comply with IEC60439-1, GB7251.1, JB/T9661 and other relevant standards. The frame is a combined structure, and the basic frame is assembled by C-type steel; Each cabinet is divided into three rooms, namely horizontal busbar room, drawer chamber and cable room. The compartments are separated from each other by steel plates or high-strength flame-retardant plastic functional plates, and the upper and lower drawers are separated by metal plates with ventilation holes to effectively prevent flashover caused by faults of switching elements or accidents caused by short circuit between buses and other lines; Compact design: more functional units can be accommodated in a smaller space; The structural members are versatile and flexible in assembly. With E=25mm as the modulus, the structure and withdrawable units can be combined at will to meet the needs of system design; The busbar is protected by high strength flame-retardant plastic functional plate with high insulation strength, which has the performance of anti fault arc, making the operation and maintenance safe and reliable.
