As a responsible and forward-looking enterprise, we decided to develop the ARV-12 series of environmentally friendly gas cabinets
on the basis of the manufacturing experience of the original SF6 ring counter for many years, and adhering to the environmental protection and intelligent product design concept. The idea is to use atmospheric air in the content of up to 78% of the N2 gas (or dry air, the two materials are extremely simple and simple to the air pollution is minimal, even negligible) as the auxiliary insulation of the switchgear. In addition, this type of switch vacuum bubble will learn from our production of solid-sealed pole column breaker related pole insulation program for the technical rely on the development of the core of the switch. Isolated earthing switch to the existing SF6 inflatable cabinet ring net cabinet isolation grounding switch to optimize and to a certain extent, a unique innovation to better meet the use of environmentally friendly gas cabinet conditions!

Note: If the equipment to be in a special, harsh environment to run,
please inform us in advance the relevant technical staffl
Technical characteristics:
intelligent distribution network of basic equipment, maintenance-free fixed vacuum switch program for the upgrading of the distribution
network to provide solutions.
vacuum arc, environmentally friendly compact structure without SF6 greenhouse gas, safety and environmental protection.
split phase insulation structure, no phase short circuit explosion risk.
equipped with intelligent components to meet the needs of smart grid.
small size, compact structure, easy operation and maintenance.
.combination of flexible solutions to meet the user's various power distribution program.
Applicable to 12kV power system, the rated current of 630A,shortcircuit breaking current 20kA.
The maximum transfer current up to 3150A, to meet the load switch E3 level requirements. The circuit breaker meets the E2 level breaking up
to 30 times.DC component value≥46%
The switchgear innovative atmospheric pressure GIS air insulation structure and sealed box patented structure, insulation is stable and reliable, with self-healing ability, while eliminating SF6inflation due to pressure caused by leakage and the ability to reduce the risk of insulation, but also do not use the presence of the Bureau The loss of solid insulation caused by the ability to penetrate the insulation is in line with the State Grid Corporation of environmentally friendly products "vacuum as the main insulating arc medium, while environmental protection gas as the auxiliary insulation measures the maximum possibility of the use of solid insulation support "The current program is the most reliable cut more mature program. In addition, the product design concept is: long life, maintenance-free, based on the concept of a new design compact, highly reliable fixed switch products, fully meet the national network companies and industry advocacy of the "life cycle management" 40 years of service life requirements.
