The SF6 gas insulated sectionalizer is equipped with an electrically operated, spring- charged operating mechanism. The closing operations are performed after the spring for opening operation is fully charged, and a spring-charged operating mechanism is applied to perform fast and accurate opening operations with little energy.
The sectionalizer is equipped with voltage sensors in each bushing on both sides, and current sensors in each bushing on the source side to measure electrical quantities of distribution lines.
In order to guarantee constant opening and closing speed and operation reliability, a sufficiently field proven mechanism is adopted.
The tulip-shaped contacts made of material with excellent electrical properties guarantees stable mechanical and electrical operation performance.
