The GR-SF6-12KV-F36 is a sealed SF₆ gas bag unit intended for compatible medium-voltage load-switch and ring-main-unit assemblies. It forms the gas-containing compartment around the specified switching assembly and must match the electrical and mechanical design of the connected switchgear.
This is not a universal replacement part. Enclosure dimensions, conductor interfaces, operating-mechanism linkage, mounting points, rated voltage and current, gas filling pressure or mass, sealing arrangement, and test requirements vary by manufacturer and model. Selection from appearance alone can create serious compatibility and safety risks.
Provide the switchgear brand and model, nameplate, system voltage, rated current, single-line diagram, dimensional drawing, operating mechanism details, photographs, and existing gas-compartment reference. Final construction, SF₆ handling requirements, factory tests, documentation, and destination compliance must be confirmed in the accepted quotation.
Where it performs.
| Size / option | Where it performs | Selection note |
|---|---|---|
| FLN36 load switch | 12 kV · 630 A | 50 kA peak making; 630 A active-load and closed-loop breaking current |
| FLRN36 switch-fuse combination | 12 kV · 125 A | 50 kA short-circuit breaking; 1,700 A transfer current; maximum 125 A fuse |
| Both configurations | 20 kA / 4 s main circuit | 20 kA / 2 s earthing circuit; 42 / 48 kV power-frequency withstand |
| Both configurations | 75 / 85 kV impulse withstand | Phase-to-earth / across open contacts respectively |
| Sealed SF₆ compartment | 0.045 MPa at 20°C | Confirm leakage requirement, filling procedure, mechanism, and destination rules |
The listed values describe the supplied reference design, not a universal replacement standard. Final compatibility requires the installed switchgear model, mechanism, drawings, dimensions, ratings, gas data, and interface details.
