GB/T 22065-2026Pressure type SF6 gas density monitor (English PDF)

GB/T 22065-2026 is the English-translated version of 压力式六氟化硫气体密度控制器.

This standard concerns the pressure type SF6 gas density monitor, an instrument fitted to electrical equipment insulated with sulfur hexafluoride to supervise the condition of the gas. It is of interest to makers of gas-insulated switchgear, instrument manufacturers, power utilities, substation maintenance teams and test laboratories, who rely on such monitors to supervise gas insulated equipment in service.

The document is a recommended national standard, issued on 28 September 2026 and effective from 1 April 2027. It replaces GB/T 22065-2008, so product specifications and procurement documents that cite the older edition may need revision. Use is voluntary unless it is invoked by a purchase contract or industry rule. Equipment suppliers selling switchgear into the Chinese grid, and engineers comparing domestic instrument requirements with other regional practice, can read it to see how this device is defined and handled under the national system.
