40.5kV SF6 dead‑tank circuit‑breaker, rated current 1600‑3150A, short‑circuit breaking current 25‑31.5kA, self‑blast arc‑extinguishing, three‑phase post‑type porcelain insulator for outdoor substation.
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.

Um baixo valor de descarga parcial comprova a integridade do isolamento interno, reduz o risco de envelhecimento do isolamento e prolonga a vida útil total dos equipamentos de alta tensão. Entre em contato conosco para obter os dados de teste relevantes.
Reflete a capacidade de ligar e desligar linhas aéreas em vazio, um indicador importante para a seleção de equipamentos de distribuição e subestações. Por favor, entre em contato conosco para esclarecimentos sobre os limites de aplicação.
O excesso de umidade pode causar condensação interna, reduzir a rigidez dielétrica e acelerar a corrosão dos componentes metálicos e isolantes internos. Entre em contato conosco para obter orientações sobre o manuseio de gás no local.
