What Is An Inflatable Cabinet?

Gas filled cabinet, the full name of which is fully insulated and fully enclosed ring main unit, is a high-voltage switchgear, which is filled with sulfur hexafluoride (SF6) gas as an insulating medium. This design gives the gas cabinet the following characteristics:

Compact structure: Due to the use of SF6 gas as an insulating medium, the gas cabinet is relatively small in size and is suitable for places with limited space.

High safety: The gas cabinet seals high-voltage components (such as busbars, circuit breakers, locking switches, transformers, etc.) in a shell filled with SF6 gas, effectively avoiding the influence of the external environment (such as condensation, pollution, small animals and chemicals).

Environmental adaptability: The gas cabinet has good sealing and can operate stably under harsh environmental conditions, such as high altitude areas, humidity, dust, etc.

Easy maintenance: The gas cabinet adopts an oil-free switch design, especially a vacuum switch with little or no protection, which greatly reduces the workload of protection and maintenance.

Widely used: Inflatable cabinets are widely used in various high-voltage equipment, such as distribution switch stations, box-type substations and cable distribution boxes, to meet the needs of end users or network nodes.

The model of the inflatable cabinet is usually RM6-12. According to the configuration switch used, it can be divided into C, F, V, D, G, PT and other units. According to its box, it can be divided into single-body type and shared compartment type. This equipment is widely used in various high-voltage equipment because of its small footprint, low cost and simple maintenance.
