MNS/GCS(GCK) withdrawable switch cabinet
Product overviewProduct overview
device is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textiles, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with high degree of automation and computer interface, it is used as a low-voltage complete set of power distribution equipment for power distribution, centralized motor control and reactive power compensation in power generation and power supply systems with three-phase AC frequency of 50(60)Hz, rated working voltage of 380V(400) and (660) and rated current of 4000A or less.
device can form frame structures and drawer units of different schemes, and adopts high-strength flame-retardant engineering plastic components, which effectively enhances the protective performance. The drawer unit has the characteristics of small size, strong function, high interchangeability, convenient replacement and maintenance, and reliable contact.

Structure DescriptionStructure description
device is a C- profile combined structure, and all the structures of the frame are galvanized or made of aluminum-zinc plate. Through self-tapping locking screws, grade 8.8 hexagon screws are firmly connected to each other to form a basic frame, and then according to the needs of scheme changes, corresponding doors, sealing plates, partitions, mounting brackets, bus bars, functional units and other parts are added to form a complete device. The size of built-in components and compartments of the device are modularized (module single E = 25mm). The cabinet body can also adopt the rear outlet mode, but the main bus must be placed on the top of the cabinet. The vertical channel adopts a half-block function board for easy maintenance.
