RHD‑245 SF6 dead‑tank circuit breaker, 245kV, rated current 3150‑5000A, short‑circuit breaking current 40‑63kA, self‑blast arc‑extinguishing, three‑phase SF6 gas insulated high‑voltage circuit‑breaker.
This product flyer acts as technical reference for high‑voltage SF6 dead‑tank circuit‑breaker, supporting tender drafting, transmission substation project evaluation and pre‑sales technical review.
The product complies with IEC 62271‑100 and GB/T 1984 standards. This datasheet covers full set of technical indicators including lightning impulse and one‑minute power‑frequency withstand voltage, specified creepage distance range, partial discharge requirement, SF₆ alarm‑block pressure threshold, gas moisture limit, annual gas leakage rate, mechanical endurance and special reclosing operation sequence O‑0.3s‑CO‑180s‑CO.
It features three‑phase post‑porcelain‑insulator structure and pointer‑type density relays for continuous SF6 gas pressure and density supervision. The document also defines power supply parameters for heater, energy‑store motor and control circuit, as well as first‑open‑pole factor, cable‑line charging breaking capacity and time‑related switching performance parameters.
Custom‑made solutions including design, assembly and factory test are available for EPC projects. Please contact us for complete type‑test reports and full operation‑maintenance manuals.
230-252kV Dead-Tank SF6 Breaker: 9-degree seismic, ≤1% leakage. High-reliability for 220kV+ grids & new energy bases.
Outdoor dead tank SF6 circuit breaker direct supply for 362kV systems, delivering reliable high-voltage protection for transmission networks.
Three-phase AC dead tank SF6 circuit breaker source manufacturer for 72.5kV systems, delivering reliable high-voltage protection and switching solutions.
Opening and closing time reflect mechanism response speed, which directly affects fault clearing speed and grid transient recovery condition. Please contact us for time‑sequence analysis material.
Signals activate when SF6 gas density drops to preset thresholds. Alarm reminds operators of gas supplement; blocking prohibits switching operation to prevent internal insulation failure. Please contact us for setting reference.
Three‑phase integrated layout optimizes overall footprint, reduces foundation space occupation and simplifies on‑site cabling work compared with single‑phase separate solution. Please contact us for layout comparison details.
