  • SF6 Handling: Why the Full Lifecycle of Product Matters

    Oct 27, 2016The dielectric and heat transfer characteristics of sulfur hexafluoride (SF 6) has made it the insulator of choice for circuit breakers, disconnectors, and switchgear in the power transmission and distribution industry.. For decades, the TD sector has relied on SF 6 to effectively quench arcs and to cool and protect its equipment. However, SF 6 is a very powerful greenhouse gas, 23,900 times

  • Air Insulated Switches (AC and DC)| MV Technology Solutions

    Arc-Extinguishing Principle In switch disconnectors, the arc is not extinguished in a vacuum interrupter or SF6, but instead, operates according to the principle of a hard-gas switch. Effectively, the arc splits off some gas from an insulating material which surrounds the arc closely. This gas quenches the arc promptly and effectively.
