RDK electronic sectionaliser: 12-40.5kV, 200-315A, lightning impulse 110-185kV, 1s short-time 10kA, making peak 16kA. For overhead distribution network fault-section isolation.
RDK pole‑mounted electronic sectionaliser needs no external auxiliary supply, counts upstream recloser‑tripping times for fault isolation with visible open gap after tripping, manual closing via insulated stick and maintenance‑free. It complies with relevant IEC/ANSI sectionaliser standards with configurable counting parameters.
Three-phase electronic pole mounted sectionaliser for 12kV 40.5kV systems, enabling fast fault isolation and enhanced overhead grid reliability.
Pole-mounted vacuum automatic sectionalizer for 12kV and 24kV lines, enabling smart fault isolation to improve grid reliability.
Rockwill voltage-time type intelligent sectionalizer complete set for 12kV distribution automation. Fault isolation, power restoration, remote monitoring via GPRS/fiber.
No external auxiliary power source is required. It takes energy from built‑in current‑transformer, completes fault‑current detection and counting logic by internal micro‑controller.
After permanent‑fault removal, operators can manually close it by insulated operating rod. No spare‑parts replacement is required. It will auto‑reset if fault is temporary without reaching count threshold.
Three conditions must be met simultaneously: fault current exceeds pickup setting; preset counting‑times (1‑4 times) are reached; line loses voltage and residual current below 300 mA.
