Medium-voltage metal-enclosed switchgear designed to remove environmental harm — no SF6, no fluorinated greenhouse gas, recyclable steel enclosure and sealed vacuum interruption. The green choice for distribution and industrial substations.
Conventional medium-voltage switchgear earns its environmental footprint mainly from one source: the SF6 gas sealed inside. Our eco-friendly medium voltage switchgear removes that source and addresses the rest of the lifecycle too.
Insulation by dry air or solid epoxy. Nothing with a global-warming potential sealed in the tank.
Steel enclosure and copper busbar are standard recyclable materials — no specialized gas recovery or hazardous-waste disposal.
Sealed vacuum interrupters are designed for decades of service — fewer replacements, less waste over the asset life.
No fluorinated gas filling line, no gas-handling PPE, cleaner production and simpler supply chain.
Zero CO2-equivalent leakage. No periodic gas-density monitoring or top-ups that can vent gas to atmosphere.
Air insulation means no asphyxiation risk for installers and maintenance teams in cable pits or basements.
Aligned with F-gas phase-down and ESG procurement policies — ready for green and net-zero tenders.
Optimized conductor design and optional smart monitoring reduce losses and support demand-based operation.
Recycle as standard metal-enclosed gear. No gas recovery contractor, no hazardous disposal fees.

Yes. The vacuum circuit breaker handles current interruption, and dry air or solid insulation handles steady-state voltage. Panels are type-tested to IEC 62271-200 to the same ratings as SF6 equipment.
Three things: no SF6 (zero GWP leakage), a recyclable steel enclosure with no gas-recovery step at end of life, and long-life sealed vacuum parts that reduce replacement waste.
Yes. SF6-free and zero-GWP are the specific environmental clauses most modern utility and green-project tenders require, and we supply the supporting documentation.
Yes — breaker, metering, bus-tie and feeder panels engineered to your scheme and labeled under your brand.
