HXGN-12 high voltage switchgears
With the rapid development of the national economy, the power supply loop is widely used, more and more demand for high voltage switchgears and high voltage load switch. Developed by our company HXGN-12F (F, R) high pressure ring net switch cabinet can be ABB company's nal (f) load switch, Italy VEI company ISARC series load switch and FN series and ZFN series load switch, the mode of operation with manual, electric or electric, manual double
In order to adapt to the mode of operation of remote operation control under control, meet the requirements of urban and rural power grid construction transformation. The distribution system is suitable for places of factories, high-rise buildings, residential areas, ring network power supply or dual power radiation power supply system, accept, distribution and protection, and is also suitable for loading in box substation. Product performance in line with IEC298, IEC420 and GB3906 standards.

HXGN-12 (F, R) profile type ring net switch cabinet frame adopts the advanced technology at home and abroad pull assembled;
] cabinet prison of the overall structure, the top of the cabinet body is bus room, in front of the busbar compartment for instrument room, ask separated by a metal plate, cabinet put oneself in another's position in the upper load switch installation position, lower cable inlet and outlet and other element, such as current, voltage transformer installation position;
A metal separator between - cabinet and cabinet, a bus chamber between the insulation casing, to ensure the safe operation of the power supply in each;
The door and the terminal sealing plate by electrostatic powder spray. Using the above methods and materials to make the switch cabinet has a strong anti-corrosion ability;
The cabinet has a perfect device for preventing electric misoperation;
The cabinet has the advantages of small size, small occupation area, compact structure, safe and reliable;
The shell protection grade reaches IP4X.
