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.

We design around existing cable and bus arrangements and review your layout drawings before manufacturing to minimize civil work and re-cabling.
Yes. Insulation is dry air or solid epoxy and interruption is vacuum — no SF6 or any fluorinated gas is sealed into the panels.
Yes. You can replace only the ring unit with our SF6 Alternative RMU, or go for full panel replacement — we scope both.
Yes. We manufacture under your brand and supply test reports, drawings and FAT packages for the tender and handover.
