◇When the equipment is installed above 1000 meters above sea level, it should be specified so that the company can adjust the SF6 pressure during manufacture. ◇If special harsh conditions are involved, please be sure to consult the company.

◇High security
All live parts are enclosed in SF6 air box to achieve full sealing and no green; with mechanical interlocks that meet the requirements of five defenses, to prevent the occurrence of misoperation;
The inlet and outlet cables are fully insulated and fully sealed and can be connected by touch to ensure personal safety to the greatest extent; the box is equipped with an air pressure monitoring device to realize real-time monitoring of air pressure during operation;
There is an explosion-proof pressure relief device under the rear of the air box, which has passed the internal combustion arc test of the authoritative organization.

◇ Flexible plan
The way of entering and exiting the line is flexible, which can realize the left, right and bottom entry (exit) line;
The combination method is flexible, and all units can be combined arbitrarily with unlimited expansion; the built-in busbar expansion method is adopted to fully meet the requirements of usability, economy and aesthetics; the design scheme is flexible and can meet the requirements of users on site.

◇Compact and reasonable structure
All unit modules have the same size (except the metering module), and the compact size does not affect the convenience of construction.

◇Economy
Maintenance-free; small footprint, cost-effective; service life more than 30 years.

◇Wide application
The stainless steel plate of the air box is sealed and welded by robot automatic TIG, and the protection level reaches IP67. It can be installed in humid, dusty, salty, mine and any air pollution places without taking special precautions.

◇Intelligent
It can provide supporting electric operation device and power distribution automation terminal equipment to realize intelligent switchgear with "four remote" function, and meet all the requirements of smart grid for this type of equipment.
