>>Overview
Sate-12/24 SF6 inflatable ring network switchgear (hereinafter referred to as "inflatable cabinet"} is a new generation of switchgear, the main switch adopts the special load switch for the gas cabinet and the special vacuum circuit breaker, and the whole primary circuit components are copper rows, the load switch, vacuum circuit breaker, grounding switch, sealed to the SF8 gas box. That is compact and expandable, suitable for power distribution automation. Study gas cabinet has a compact structure, flexible operation, reliable interlocking and other characteristics, for a variety of different applications (especially places with harsh environments), different user requirements can provide satisfactory technical solutions. The adoption of sensing technology and the latest protection relay, coupled with advanced technical performance and lightweight and flexible assembly programme, can fully meet the different needs of users. Inflatable cabinets are suitable for small secondary substations of electric power system, opening and closing stations, box-type substations, residential districts, industrial and mining enterprises, large shopping malls, especially for airports, subways, railways and other occasions with high requirements for electricity.

>> Main features:
1. Cabinet structure: the gas compartment is made of 3mm thick stainless steel plate, which is welded by welding robot after laser cutting and NC bending processing. The other compartments are made of high quality cold rolled steel plate, which is assembled after NC bending processing. It has the characteristics of high precision and good strength. Each functional unit is an independent module, which is extremely convenient to assemble. Each sealed compartment of the cabinet is equipped with independent pressure relief channels to ensure personal safety and equipment operation to the maximum extent.
2. Inflatable SF6 metal-enclosed full insulation series inflatable cabinet with SF6 gas as the quenching and insulation medium; switch cabinet is fully sealed, fully insulated structure; bus, switch and live parts are completely enclosed in stainless steel shell, the cavity filled with SF6 gas of 1.4 bar, the protection level reaches IP65; the whole switch device is completely unaffected by external environmental conditions, even in extreme cases such as short-term water flooding, it can ensure normal operation of the switch, and the product is free of maintenance for life. Switchgear is equipped with perfect "five-prevention" interlocking device to completely eliminate personnel and equipment operation faults caused by human misoperation; all switchgears are equipped with reliable safety pressure relief channels, which can guarantee the personal safety of operators in extreme cases. Switchgear is divided into fixed unit combination and expandable unit combination; Switchgear usually enters and exits from the front, and can also realize side outgoing or side expansion according to different installation positions; Cabinet size is small and convenient for installation, and can be suitable for narrow space and poor environmental conditions; Switchgear can be configured with electric, remote control and monitoring devices according to different requirements of users.
