XK-12 Product Overview:
XK-12 series box type opening and closing has the characteristics of compact structure, strong set, safe and reliable operation, convenient maintenance, beautiful appearance and convenient movement. It is widely used in high-rise buildings, residential quarters, stations, terminals, ports, parks, industrial and mining enterprises, and other three outdoor voltage distribution systems with rated voltages of 6-10kV and rated frequency of 50Hz. It is used for receiving and distributing electric energy, with control, protection and Monitoring and other functions.
Structural features
1. The opening and closing is made up of various types of switchgear according to the power supply requirements, through a certain relationship, the internal main switch is mainly load switch and circuit breaker;
2. The skeleton of the opening and closing station is made of channel steel and angle steel which are economically treated with anti-corrosion treatment, and has sufficient mechanical strength and rigidity;
3. The shell material is made of cold-rolled steel plate, stainless steel plate, aluminum alloy plate, composite color plate or glass fiber reinforced cement;
4. The top cover of the opening and closing station is a double-layer structure, which has strong anti-exposure, anti-radiation and heat insulation functions;
5. In order to be suitable for use in humid and high temperature areas, the temperature and humidity controller can be set in the opening and closing. When the humidity reaches a certain value, the controller starts the heater to automatically dehumidify. When the temperature in the opening and closing room reaches a certain value, the controller starts the exhaust fan. To reduce the indoor temperature;
6. The rotatable connection part of the outer casing of the opening and closing is rubber sealed and has the function of preventing rain;
7. The color of the cabinet is optional, so that it is coordinated with the surrounding environment.
