The RCW series outdoor vacuum Auto Circuit recloser is designed for overhead distribution lines and substation applications across all voltage classes from 11kV to 38kV. It is specifically engineered to improve grid reliability by providing automated control, protection, and fault detection for medium-voltage power systems.
Q:How does the outdoor vacuum Auto Circuit recloser enhance power grid stability?
A:This outdoor vacuum Auto Circuit recloser features an intelligent automatic reclosing function that performs multiple cycles to clear transient faults. By automatically restoring power after temporary issues, it significantly reduces outage durations and minimizes the need for manual intervention by utility teams.
Q:What makes this outdoor vacuum Auto Circuit recloser suitable for harsh environments?
A:Built as a rugged, outdoor-ready solution, the outdoor vacuum Auto Circuit recloser features an IP66-rated enclosure and a specialized corrosion-resistant coating. This ensures the unit operates reliably in extreme temperatures ranging from -30°C to +40°C, high humidity, and even salt-fog coastal conditions.
Q:Does the manufacturer offer customization for the outdoor vacuum Auto Circuit recloser?
A:Yes. As a leading source manufacturer, we provide full-chain R&D and production for the outdoor vacuum Auto Circuit recloser. We can customize parameters—including specific voltage ratings like 21.9kV or 25.8kV, communication protocols, and protection logic—to ensure the equipment matches your regional grid standards and project needs.
Yes. Rockwill provides a comprehensive OEM/ODM program for the RCW vacuum recloser. However, we are very selective in our partner selection — we specifically seek manufacturers and local partners with strong technical capabilities, solid engineering background, and local service capacity. Our goal is to partner with entities that can not only distribute but also provide local technical support to promote our advanced technology.
Two types: magnetic actuator (M/G, mechanical life 30000 times) and spring mechanism (N, mechanical life 10000 times). Magnetic type can add manual closing function with code “C”.
It integrates control, overcurrent protection, measurement, communication, fault detection and online opening‑closing monitoring, matched with dedicated recloser controller.
