The ZJ Series Vacuum Pump Unit represents the pinnacle of engineering designed to handle the rigorous demands of high-voltage electrical infrastructure. Unlike standard pumps, this transformer vacuum pumping system is built as a complete industrial solution, integrating multiple components into a single, mobile unit.

Connect the vacuum pump of the SF6 gas recovery and refilling equipment with the circuit breaker's gas filling valve, start the vacuum pump, and vacuum the gas chamber to an ultimate vacuum of ≤10Pa, and maintain the vacuum state for 5-15 minutes to ensure that all residual air and moisture are removed.
