40.5‑145 kV hybrid gas‑insulated switchgear, ≤3150A rated current, up‑to‑40kA short‑circuit breaking, factory‑preassembled modular bay, low SF6 usage, digital‑substation‑ready for transmission‑substation new‑build & retrofit.
This PDF product manual serves utility clients, EPC contractors and engineering consultants for project specification writing, technical comparison and tender evaluation. This hybrid gas‑insulated switchgear complies with IEC 62271‑1, IEC 62271‑100, IEC 62271‑102 and ANSI‑related standards.
It adopts factory pre‑assembled modular bay design with self‑blast circuit‑breaker, integrated three‑position disconnector‑earthing‑switch and externally‑mounted current transformers, keeping open‑type air‑insulated bus‑bar.
Manual includes full electrical ratings, SF6 annual leakage ≤0.5 %, mechanical‑life 6000 operations, O‑0.3s‑CO‑180s‑CO operating‑sequence, service temperature ‑40 ℃ ~ +40 ℃, IP54 protection, pollution‑class‑IV adaptability, seismic‑resistance capability, both conventional and IEC 61850‑based digital‑substation compatible options.
It highlights compact footprint, reduced SF6‑gas‑usage, 25‑year low‑maintenance service‑life, short‑on‑site‑installation cycle, indoor / outdoor / rooftop mounting feasibility. Custom‑configurations cover bay layout, instrument‑transformer selection, surge‑arrester integration and project‑specific factory‑acceptance‑test.

Hybrid gas insulated switchgear for 40.5kV to 245kV, combining compact GIS design with conventional component flexibility for reliable HV protection.
Hybrid gas insulated switchgear (HGIS) for 145kV, offering compact, reliable protection with flexible configuration.
Compact hybrid gas insulated switchgear (HGIS) for 72.5kV to 170kV, combining GIS compactness with AIS flexibility for reliable HV protection.
Core gas‑filled modules adopt 25‑year low‑maintenance‑design; regular work mainly includes gas‑density monitoring, external‑inspection of bushings and mechanism checking.
Bus‑bar section follows conventional AIS‑maintenance practice. Please contact us for recommended maintenance‑schedule.
Key items include ambient‑temperature range, altitude above sea‑level, pollution grade, seismic requirement, installation form (indoor/outdoor/rooftop), foundation condition and substation expansion‑planning. Please contact us for site‑assessment checklist.
It combines strengths of both solutions. Compared with GIS, it saves cost by removing enclosed gas‑busbar and cuts SF6 consumption.
Compared with AIS, it greatly reduces footprint; factory pre‑assembly shortens site work and brings medium‑level maintenance workload. Please contact us for side‑by‑side comparison document.
