This PDF product flyer is a technical reference for medium‑high‑voltage SF6 dead‑tank circuit‑breaker, used for tender comparison, preliminary project selection and pre‑sales technical evaluation. The product follows IEC 62271‑100 and GB/T 1984 standards.
This datasheet records full‑set performance indicators including lightning impulse and one‑minute power‑frequency withstand voltage, creepage distance, partial discharge requirement, SF₆ alarm‑blocking pressure threshold, gas moisture limit, annual gas leakage rate, mechanical operating life, first‑open‑pole factor 1.5, 4‑second short‑circuit duration and O‑0.3s‑CO‑180s‑CO special reclosing operation sequence.
It is equipped with pointer‑type density relays to monitor SF6 pressure and density in real‑time, and specifies power‑supply parameters for anti‑condensation heater, energy‑store motor and control circuit. Custom‑manufacturing services covering design, assembly and factory test are available for substation projects. Please contact us to get complete outline dimension drawings and full set of type‑test reports.
