RHD‑170 SF6 dead-tank circuit breaker, 170kV, rated current 3150‑4000A, short-circuit breaking current 31.5‑50kA, self-blast arc-extinguishing, three-phase SF6 gas insulated high-voltage circuit breaker.
This product flyer is the technical brochure for high‑voltage SF6 dead‑tank circuit breaker, designed for tender preparation, substation project evaluation and pre‑sales technical reference.
The product meets IEC 62271‑100 and GB/T 1984 standards. This brochure covers comprehensive technical indicators including lightning impulse withstand voltage, power frequency withstand voltage, creepage distance, partial discharge, SF6 gas alarm and locking pressure, gas moisture limit, annual gas leakage rate and mechanical operating life, together with standard reclosing operation sequence O‑0.3s‑CO‑180s‑CO.
It adopts integrated three‑phase tank structure with outdoor porcelain bushings and SF6 density monitoring relay to continuously track gas status. The document also specifies the power configuration for heater, energy storage motor and control circuit, as well as first‑open‑pole factor, capacitive current breaking performance and switching time parameters.
Customized technical solution including design, assembly and factory acceptance test is available for global EPC projects. Please contact us to obtain complete type test certificates and full operation & maintenance manuals.

Il tasso annuo di perdita di gas SF6 è l'indicatore principale, che riflette l'affidabilità della tenuta del corpo del serbatoio e dei giunti di tenuta nel corso degli anni di esercizio. Si prega di contattarci per i dati dei test di perdita.
Questa sequenza operativa definisce i compiti di interruzione dei guasti e di richiusura automatica richiesti per le linee di trasmissione aeree e richiede una verifica di coordinamento con le impostazioni di protezione della rete locale. Si prega di contattarci per il supporto al coordinamento tecnico.
