Fully Insulated inflatable cabinetsIs a high-voltage components sealed cabinet, in order to protect the effect, the current inflatable cabinet market takes into account the requirements of the inflatable cabinet manufacturing many aspects, to judge the quality of the inflatable cabinet generally has two reference aspects: welding and sealing. When welding, the inflatable cabinet is positioned as a domestic high-end inflatable ring cabinet. All gas tanks are made of 3.0 mm imported stainless steel plate, using the Japanese rotary channel active welding and Panasonic welding manipulator welded to ensure the sealing of the gas tank.

Sealing aspect: Filling the SF6 gas in the gas tank and leaking the SF6 filling equipment by vacuum box helium mass spectrometry. Leakage rate meets the national standard requirements of 0.5% per year. All live parts are sealed in the stainless steel gas chamber, greatly improving the safety performance of electrical products, so that the protection level of the tank shell to reach IP67.

China's topography is low in the west, the mountains account for 33%, and the high Altitude area accounts for 26%. The average elevation of the Qinghai-Tibet Plateau is more than 4000 meters, and the vast highlands and basins in the north and east of the plateau are between 1000 and 2000 meters above sea level. At high altitudes, the climate is complex and varied, often with moisture, condensation, salt mist and typhoons. In addition, with the development of the western region and the increasing prosperity of industry and transportation, the power grid switchgear is also highly susceptible to pollution and corrosion. Traditional distribution network with air insulation switchgear, limited by this environmental conditions, can not meet the requirements, and began to gradually upgrade. 12,000 kv Cabinet gas insulated metal closed switchgear (hereinafter referred to as C-GIS) although only a few years of history in China, but due to its small footprint, high degree of intelligence, maintenance-free, perfect working conditions, has gradually become a new choice. In recent years, Sichuan, Yunnan, Guizhou have organized several large-scale power grid switchgear transformation, the traditional 15-20-year update cycle changed to continuous frequent updates. Especially for some newly started power grid projects, starting from the design source, choose to configure 12kv C-gis to meet the necessary conditions for normal use in a certain period of time. At present, C-GIS in metallurgy, petrochemical, mining, development zones, urban rail transit, high-rise buildings and other fields of increasing application.
