Metal-enclosed medium-voltage switchgear designed to drop in where legacy SF6 panels reach end of life — same function, vacuum interruption, zero-GWP air or solid insulation, no greenhouse gas.


Installed SF6 switchgear is aging, and regulations are tightening around fluorinated gases. End-of-life is the natural, lowest-disruption moment to switch to an SF6-free alternative.
SF6 replacement switchgear lets you retire old SF6 panels without reintroducing the same gas. Instead of refilling and servicing aging SF6 equipment, you install new, type-tested panels insulated by dry air or solid epoxy and broken by sealed vacuum — a eco-friendly medium voltage switchgear solution that also resolves your F-gas reporting and recovery obligations. For the RMU side of the ring, see our SF6 alternative RMU.
Replace at retirement rather than extending service — avoids pouring money into aging SF6 gear.
Panels engineered around existing cable and bus arrangements to minimize civil and re-cabling work.
Dry air or solid insulation means nothing with a warming potential is sealed in the new panels.

Our dry air switchgear manufacturer line builds the breaker, metering, bus-tie and feeder panels you need, to your one-line diagram.
The replacement is functionally identical to the old SF6 board — incoming breaker, feeder protection, metering and bus-tie — but the insulation is air or solid and interruption is by vacuum. If you are deciding between insulation routes, our comparison guides lay out the engineering trade-offs: read dry air vs SF6 switchgear for the retrofit case and pure air vs SF6 switchgear for the environmental and dielectric comparison.
