Our ROCKWILL 22kV pole-mounted automatic circuit recloser is an integrated overhead power protection solution, composed of a vacuum circuit breaker for circuit interruption, an intelligent electronic controller for overcurrent detection and recloser actuation, and a matched interconnection control cable. This Smart Recloser design supports reliable switching and protection for overhead distribution lines.
It supports single-pole or double-pole installation, and can be mounted on pole tops for overhead line switching or installed on frames inside substations for flexible application. Committed to continuous technological innovation and standardized management, we provide reliable 22kV reclosers for global power distribution projects. Our role as an Outdoor Recloser Supplier covers both standard and customized production.

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.
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.
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.
The Rockwill standard smart recloser offers high precision with a wide measuring range (2A–16,000A). Simply ensure your normal current is within this standard range when making a selection.
Yes. In addition to the standard 2A–16,000A range, Rockwill provides custom-configured units for ultra-low current measurement and protection in the 0.1A–2A range.
