Product Features:
SF6 Gas Vacuumizing and Filling Device with Four-Level Recovery Cart Mainly used for vacuumizing and vacuum measurement during installation, operation, and maintenance of porcelain-clad SF6 circuit breakers, transformers, and other SF6 electrical equipment. RTQC-60 is a compact SF6 gas filling and evacuation device, with the entire filling and vacuumizing system mounted on a very sturdy metal cart frame, allowing smooth movement even on gravel roads. This device features high efficiency in vacuumizing and gas filling, low energy consumption, a phase-sequence auto-switching system for the power supply, a high-precision thermocouple vacuum gauge, and is simple and practical. The control system uses advanced SF6-specific valves, and the whole unit is compact, lightweight, and low-noise.
