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 (Sulfr hexafluoride) 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

sf6 gas gas measuring devices – Synergy Power Systems

The Sulfr hexafluoride Multi Analyser is a user and maintenance-friendly device which guarantees high measuring accuracy. First of all, the gas is checked for decompositions products. If critical SO2 values are determined the measurement can be interrupted. In case of contaminated sf6 gas the complete measuring gas can be recovered from the internal vessel.Get price
