145kV SF6 dead‑tank circuit‑breaker, rated current 2500‑4000A, short‑circuit breaking current 31.5‑50kA, self‑blast arc‑extinction, three‑phase post porcelain insulator, for high‑voltage outdoor substation.
This PDF product flyer is for high‑voltage SF6 dead‑tank circuit‑breaker, supporting tender reference, preliminary project selection and pre‑sales technical evaluation. The product complies with IEC 62271‑100 and GB/T 1984 standards.
This datasheet lists full set of performance parameters including lightning impulse and one‑minute power‑frequency withstand voltage, creepage distance, partial discharge requirement, SF6 alarm‑blocking pressure, gas moisture limit, annual gas leakage rate, mechanical endurance, first‑open‑pole factor 1.5, 3‑second short‑circuit duration, cable‑line charging breaking capacity and special reclosing duty O‑0.3s‑CO‑180s‑CO.
It adopts pointer‑type density relays for real‑time SF6 gas pressure monitoring, defines power‑supply specifications for anti‑condensation heater, energy‑store motor and control circuit. Custom‑manufacture service is available covering design, assembly and factory test for substation projects. Please contact us to obtain complete dimension drawings and full type‑test reports.
