Live parts are enclosed in a sealed SF6 gas tank, highly resistant to moisture, dust, and condensation, ensuring stable and safe operation.
Built‑in mechanical and electrical interlocks prevent misoperation, protect operators, and meet strict safety standards.
Small footprint, flexible combination into incoming, outgoing, metering, and PT panels, ideal for limited space.
Sealed SF6 gas chamber requires almost no routine maintenance. Long mechanical and electrical lifespan.
Equipped with operation holes, position indicators, and live display for clear status monitoring and simple operation.
