SF6-FREE Eco Friendly Air Insulated Switchgear: Alternatives of Sf6 Gas Insulated Switchgear

Publish Time: 2025-07-14     Origin: Site

I. Introduction: The Sustainable Switchgear Imperative

Industrial plants now face a critical choice for their medium voltage switchgear: persist with climate-damaging SF6 gas insulated switchgear (GIS) or embrace true sustainability. Our SF6-FREE Eco Friendly Air Insulated Switchgear delivers identical performance in the same electrical panel footprint while eliminating greenhouse gas liabilities. As regulations ban SF6 and corporates demand net-zero operations, this breakthrough redefines modern electrical switchgear.

II. The SF6 Crisis in Industrial Power Systems

Legacy SF6 GIS threatens operational resilience:

  • Environmental Timebomb: 1kg SF6 = 23,500kg CO emissions

  • Regulatory Countdown: EU mandates >80% SF6 reduction by 2030

  • Hidden Costs: $20k+/ton toxic disposal + continuous leak monitoring

  • Safety Risks: Arc faults produce corrosive byproducts (HF, SO)

III. Eco-AIS: The Seamless Drop-in Solution

1. Physical & Electrical Compatibility
Our air insulated switchgear delivers true plug-and-play replacement:

  • Matches existing GIS electrical panel dimensions bolt-for-bolt

  • Integrates with standard substation components:

    • Vacuum circuit breakers

    • Disconnect switches

    • Ground switches

  • Preserves original feeder line electrical configurations

  • No substation layout modifications required

2. Retrofit Simplicity

  • Phase 1: Safe SF6 recovery from decommissioned GIS

  • Phase 2: Direct AIS mounting in existing substation bays

  • Phase 3: Reconnect busbars/cables (<8-hour downtime)

3. Performance Guarantees

  • Equivalent voltage levels (7.2kV–40.5kV)

  • Enhanced safety features: IP67-rated sealed compartments

  • Robust circuit protection for mining/manufacturing applications

 

IV. Critical Comparison: Eco-AIS vs. SF6 GIS

Parameter Legacy SF6 GIS Our Eco AIS
Insulating Medium SF6 (GWP = 23,500) Dry Air/N₂ (GWP = 0)
Environmental Impact Contributes to climate change Negligible climate impact
Electrical Panel Space Compact but toxic Identical clean footprint
Disposal Cost $20k+/ton hazardous processing Vent safely (zero cost)
Arc Byproducts Toxic HF/SO₂ generation Non-toxic air composition
Compliance Status Phase-out by 2030 (EU) Future-proof regulations

 

V. Industrial Plant Benefits: Beyond Compliance

1. Operational Advantages

  • Zero Retrofitting Costs: Replace GIS units without reengineering substation components

  • Enhanced Safety: Eliminate SF6 decomposition hazards near electrical equipment

  • Continuous Production: <0.5ms switching ensures stable power supply

2. Custom Solutions

  • Climate-adaptive sealing (-40°C to +55°C)

  • Seismic reinforcement packages

  • Smart sensors for real-time protective devices monitoring

3. Financial Impact

  • -40% Lifetime Costs: Eliminates SF6 tracking/disposal fees

  • ESG Value: Verifiable emissions reduction for sustainability reporting

  • Future-Proof Infrastructure: Aligns with global decarbonization mandates

VI. Conclusion: Lead the Switchgear Revolution

"SF6-Free Eco Friendly Air Insulated Switchgear is the ultimate upgrade: identical GIS performance, zero environmental debt, and seamless electrical panel integration."

Industrial plants gain:

  • 1:1 SF6 GIS replacement with GWP=0 technology

  • Zero operational disruptions during retrofit

  • Certified compliance ahead of 2030 regulations


We will work with other excellent partners to deliver more high-quality products to the world.
