Power that
holds the line.
Cubicle gas-insulated switchgear, vacuum circuit breakers and operating mechanisms — engineered in Shanghai, type-tested to GB / IEC, sealed for life. 12 kV to 40.5 kV.
One platform, 12 to 40.5 kV
From in-house VCB and mechanism R&D to complete cubicle GIS. Annual capacity above 1,000 units, with lead times of three weeks for breakers and six weeks for gas tanks.
From components to full sets.
We design and run-in the vacuum circuit breaker, disconnector and operating mechanism ourselves — then assemble the cubicle. That is the core competency, not a purchased kit.
In-house R&D of VCBs, disconnectors and mechanisms. 17 utility-model patents and 2 invention patents.
Supply-chain control and shorter development cycles through electric-field, magnetic-field and thermal-mechanical simulation.
Urban grids, data centers, wind, solar.
Wind and renewables
Collection switchgear for wind farms and new-energy plants.
Solar
Compact C-GIS for photovoltaic substations and collection points.
Data center
Compact, sealed C-GIS for critical facility MV distribution.
Urban and industry
Dense city substations, industrial parks and infrastructure.
Type-tested
GB / IEC verification. Reports ship with the gear.
Sealed for life
Helium leak-tested tanks. Annual leakage ≤ 0.01%.
Made in-house
Breaker, mechanism and cubicle under one roof.
