SF6 Gas Insulated Sectionalizer is operated by a motorized operating mechanism, and it simultaneously charges opening spring as well as closing operation when it is closed. Also, it is equipped with a spring-charged operating mechanism by low Energy for fast and accurate opening operation. There are built-in voltage sensors in each phase on each side to measure line’ data in the Sectionalizer. The field-proven driver is used, and it has reliable constant opening and closing time By using materials with excellent electrical properties at the tulip type contact point, high mechanical and electrical operation characteristics, and stability are achieved.
