Secondary switchgear IEC439, 380~660V/630~3150A/CDGGD

low-voltagepower distributionstationary

This Low-Voltage stationary type switch cabinet is developed by our company with reference to the MNS low-voltage switch cabinet produced by Swiss ABB Company. The Switch Cabinet, composed of standardized, serialized modules, is the most advanced in China. Design and Application scope The secure mechanic interlock mechanism for drawer ensures its safety and reliability. The Switch Cabinet, applicable to three-phase five-wire power supply system whose frequency, rated insulation voltage, working voltage ,and rated current are respectively 50(60)Hz, 380(400), 660V, 5000A or weaker, may be used in power stations, substations, factories, mines, buildings, hotels, airports, harbors, broadcast televisions to control the equipments generating, transmitting, distributing, exchanging or consuming power, and to offer reactive compensation, by means of capacitance compensation cabinet, for main bus-bar. Suitable choice CDGGD exchanges the switch board switchgear of hypobaric and suitable for electric users, such as power plant, transformer substation, industrial and mining enterprises, etc. as exchanging 50 Hz, working voltage 380V of amount, the specified electric current is regarded as power to the distribution systems of 3150 A, light and that electric energy of equipment was changed, assigned and controlled to use distribution. Tolerance electric current of this product is up to 50 KA in short-term.
