Environmental friendly technology reduces use of sulfur fluoride
TOKYO, January 17, 2019 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed two technologies for gas-insulated switchgears: an arc-cooling technology that achieves a 25 percent improvement in the interruption of electrical current in sulfur-fluoride (SF6) gas-insulated switchgears used in high-voltage power systems, and a high-density dielectric coating technology that improves insulation performance by 30 percent in high-voltage conductors. The two technologies will contribute to the further miniaturization of switchgears and help to reduce the use of SF6 gas, which has global-warming potential that is 22,800 times greater than that of CO2.
