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.
Modul inti terisi gas mengadopsi desain perawatan rendah 25 tahun; pekerjaan rutin terutama mencakup pemantauan densitas gas, inspeksi eksternal bushing, dan pemeriksaan mekanisme.
Bagian busbar mengikuti praktik pemeliharaan AIS konvensional. Silakan hubungi kami untuk jadwal pemeliharaan yang direkomendasikan.
Item utama meliputi rentang suhu ambien, ketinggian di atas permukaan laut, tingkat polusi, persyaratan seismik, bentuk instalasi (dalam ruangan/luar ruangan/atap), kondisi fondasi, dan perencanaan perluasan gardu induk. Silakan hubungi kami untuk daftar periksa penilaian lokasi.
Solusi ini menggabungkan keunggulan dari kedua solusi. Dibandingkan dengan GIS, solusi ini menghemat biaya dengan menghilangkan busbar gas tertutup dan mengurangi konsumsi SF6.
Dibandingkan dengan AIS, solusi ini sangat mengurangi kebutuhan lahan; pra-rakitan di pabrik mempersingkat pekerjaan di lokasi dan menghasilkan beban kerja pemeliharaan tingkat menengah. Silakan hubungi kami untuk dokumen perbandingan berdampingan.
