Low-voltage withdrawable switchgear
Products Introduction
◆Low-voltage switch cabinet (hereinafter referred to as switch cabinet) is currently the most advanced low-voltage withdrawable switchgear in China. The products are composed of standardized and series modules, and the drawers have reliable mechanical interlocking devices. Users It is safer and more reliable when used. ◆This switch cabinet is suitable for AC, three-phase and five-phase power supply systems with rated insulation voltage and working voltage at and below. It can be used in power plants, substations, industrial and mining enterprises, building hotels , airports, docks and radio and television communication centers, as the control of power generation, transmission and distribution, power conversion and power consumption equipment, and reactive power compensation for their main busbars through capacitor compensation cabinets.
Low-voltage withdrawable switch cabinet< br/> Product Introduction
This product is suitable for power conversion, distribution and control of power, distribution and motor control centers in low-voltage distribution systems such as power plants, substations, petrochemical departments, factories and mines, hotels, high-rise buildings, etc. , and reactive power compensation is performed on its main busbar through the capacitor compensation cabinet. In power plants with large single-machine capacity, low-voltage power control centers and motor control centers in large-scale petrochemical and other industries, it can meet the special needs of computer interfaces. The low-voltage withdrawable switchgear is based on the requirements of the Ministry of Electric Power, the majority of power users and the design department. In order to meet the needs of the continuously developing power market for capacity expansion, computer interfaces, centralized power control, convenient installation and maintenance, and shortening of accident handling events, A new type of low-voltage shaft withdrawable switch cabinet designed based on the principles of easy installation, economy, reasonableness and reliability.
