MNS Low Voltage Switchgear advanced model new technology

Product Description

General info

MNS low-voltage drawer type switchgear (hereinafter referred to as switchgear) is developed by our company after referring to Swiss ABB's MNS series low-voltage switchgear and making comprehensive improvement.The products are composed of standardized, serial modules, and the drawer has a reliable mechanical interlock device, which makes the user safer and more reliable when using.

The switch cabinet is suitable for use in ac 50 Hz (60), rated voltage 400 v, 660 v, rated current under 5000 a and three-phase five wire of electric power supply system, can be used in power plants, substations, industrial and mining enterprises, hotel, airport, dock and radio and television communications center, for power generation, transmission and distribution, power conversion and power consumption equipment control, and through the ark to its main bus-bar capacitance compensation for reactive power compensation.

Drawing

Structural features:

The product design has fully considered the requirements of the majority of power users and design departments, which can meet the needs of the developing power industry such as the centralized control of capacity increase power, convenient installation and maintenance, and shortened accident treatment time, etc., which is safe, economical, reasonable and reliable.The product has the characteristics of strong connection ability, high breaking ability, good dynamic stability, flexible electrical scheme, convenient combination, strong series and practicability, novel structure and so on.At the same time, it can be combined with drawers and cabinets for mixed use.

Switch cabinet cabinet structure is composed of profiles (module E=25mm) assembly.As a result of using lock since tapping screw and 8.8 class high strength bolt for connection, thus high precision cabinet, good patience.
