Dead-tank SF₆ circuit-breaker: 145-170kV, standard rated normal current for transmission-substation networks. Lightning impulse, short-time withstand and making current match respective voltage classes for load & fault interruption.
Dead‑tank type with pure‑spring operating‑mechanism, built‑in CT, self‑energy arc‑extinguishing, three‑phase post‑porcelain‑insulator and pointer density‑relay for good seismic performance. All design & type‑tests comply with IEC, CEI, GB, JB, DL; custom‑manufacturing & tailor‑made solutions are available.
120kV 168kV 204kV Tank Type Vacuum Circuit Breaker (VCB): Versatile high-voltage VCBs covering 120kV/168kV/204kV, delivering reliable SF₆-free switching for power transmission networks.
145kV dry air insulated dead tank VCB, SF₆-free, vacuum arc-extinguishing, reliable for power transmission & substation applications.
36kV 72.5kV Dead Tank Vacuum Circuit Breaker: Reliable SF6-free VCBs with dry air insulation, suitable for 36kV/72.5kV medium-voltage power grids.
Perangkat ini mengadopsi mekanisme operasi pegas murni, tidak memerlukan pasokan oli hidrolik maupun udara bertekanan, dengan keunggulan struktur sederhana, keandalan tinggi, dan kemudahan pemeliharaan.
Konstruksi tangki mati mewujudkan tata letak pusat gravitasi rendah dengan kinerja seismik yang sangat baik, serta memungkinkan integrasi transformator arus bawaan di dalam unit.
Peralatan ini menerapkan prinsip pemadam busur energi mandiri tiupan mandiri yang telah mapan, yang menurunkan kebutuhan daya operasi serta meningkatkan keandalan pemutusan arus gangguan.
