ComponentsAdvantagesDisadvantagesGas Insulated Switchgear ApplicationsThe Gas insulated switchgear design can be done using different components like circuit breakers, bus bars, disconnectors or isolators, transformerslike voltage and current, earth switches, lightning arresters, and surge arrestors. When the substation is connected with gas insulated switchgear then it is called GIMES or gas insulated metal enclosed substation. This kind of technology is not invented recently but it is available for the past 30 years. In gas insulated medium voltage switchgear, SF6 gas works like an insulation material whereas the vacuum technology is mainly used for the purpose of interrupting. Even though, for both insulation and interruption, the SF6 gas can be used in several medium voltage gas insulated switchgear systems. However, for such devices, SF6 gas pressures are dissimilar for insulation as well as an interruption. For insulating, this gas pressure is usually kept under 2.5 bar, whereas for interrupting, it is ranged from 5 – 7 bar.See more on elprocusThree Phase Encapsulated Type SF6 Gas Insulated Switchgear fujielectric/products/transmission_distribution/...PDFSF6 Gas Insulated Switchgear Type SDF for 170 kV 06B1 E 0001 Gate City Ohsaki, East Tower, 11 2, Osaki 1 chome, Shinagawa ku, Tokyo 141 0032, Japan both at home and abroad.

ComponentsAdvantagesDisadvantagesGas Insulated Switchgear ApplicationsThe disadvantages of gas insulated switchgearinclude the following. 1. As compared with other substations like conventional or air insulated, these are expensive. 2. Once fault happens inside, the outage phase will be extremely long and the effect of damage will also be very severe. 3. SF6 gas acquisition, as well as its supply toward the site, is problematic 4. Maintenance is very important because the moisture otherwise dust within the compartment can cause the burst 5.

The insulating properties of commercially available insulating materials are determined by the amount of gas held inside the material and the number of gas pockets. Therefore, the higher the number of cells (which can maintain the gas stagnant) and the smaller their size, the lower the thermal conductivity of such insulating material.
