Mitsubishi Electric Develops New Gas-insulated Switchgear

Feb 04, 2019. Mitsubishi Electric Corporation has developed two technologies for gas-insulated switchgear. An arc-cooling technology achieves a 25 percent improvement in the interruption of electrical current in sulfur-fluoride (insulating gas) gas-insulated switchgear used in high-voltage power systems. Also, a high-density dielectric coating technology improves insulation performance by 30 percent in high-voltage conductors.Get price

Cold Weather Operating Problems with sf6 gas Circuit Breakers

Although the gas is nearly ideal, it does have one major disadvantage. The main disadvantage, from our perspective, is the relatively high liquefaction point of SF 6 . Figure 3 The liquefaction occurs between -10°F and -30°F, depending on the density (70psig to 95psig ranges found in circuit breakers manufactured today 3 ) of the SF 6 .Get price
