Why do modern substations fit in an elevator shaft? Gas insulation tech makes it possible!
Traditional SF₆ gas in switchgear has 23,000x global warming potential of CO₂. SH Power’s solution:
Eco-Innovation: Hybrid Gas Tech
- SF₆-N₂ Mix:
SF₆ reduced to 20% (vs 100% traditional), cutting greenhouse effect by 80%
→ Manual : Insulation strength maintained at 95kV/mm - Dual Sealing:
Laser-welded stainless steel chamber + molecular sieve , leakage <0.5%/year - Extreme Resilience:
Operates at -40℃~+50℃ with 25-year lifespan in coastal/desert areas
User Case:
Shanghai business district using SH-40.5 RMU :
- Footprint shrunk 60% – parking lot to parking space
- Maintenance costs down 45% – no gas refilling required
Global Shift: EU will ban pure SF₆ gear by 2030. Hybrid gas is becoming the green grid standard.
