TGXR6-24KV SF6 Ring Main Unit

TGXR6-24 series switchgear has standard module units and fixed combination module units. Multiple combinations can be realized through the selected extended busbars to achieve full modularization. The extended busbars are fully insulated and shielded to ensure high reliability and safety. The rich combinations of modules not only meet the needs of network nodes and end users, but also meet the needs of flexible use of compact switchgear in various secondar substations.
SF6 fully insulated ring main unit complies with IEC 62271, IEC 60420, GB/T 3906, and GB/T 11022 standards.
