  • 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.
