All live components hermetically sealed inside integrated SF6 gas tank; gas insulation blocks dust, dew and coastal salt fog for stable operation under harsh corrosive working conditions.
Superior arc-quenching performance of SF6 reduces contact ablation, much longer service life for frequent switching of PV grid-connected projects.
Integral welded airtight tank pre-filled with SF6 at factory; maintenance-free without on-site gas refilling to save long-term operation cost.
Compact vertical cabinet saves floor space vs split-type switchgear, cutting civil construction cost for commercial & urban grid renovation with limited space.
Separated compartments for instrument, switch and cable chamber; split-door layout makes inner parts fully visible for quick troubleshooting without cabinet disassembly.
Pre-assembled, wired and fully tested in factory; only on-site cable connection required without field gas filling & HV test to shorten construction period.
Optional motor drive, fault indicator and intelligent relay support remote control & fault alert for smart grid and PV energy storage projects.
