The CKWF-12 is a high-performance solution for three-phase AC 50 Hz distribution lines (3kV-12kV). Engineered for reliability, it provides advanced automatic fault diagnosis, section isolation, and power restoration capabilities.
The CKWF-12 Intelligent Outdoor Vacuum Load Switch is a new product developed by Zhuhai Kangjin Electric Co., Ltd. It is
designed for three-phase AC 50 Hz distribution lines with rated voltages from 3kV to 12kV, providing both automatic and manual operation.
Combined with an SPS power transformer and a CWFC-1 intelligent controller, it enables automatic fault diagnosis, automatic fault section isolation, and automatic power restoration for non-fault sections without requiring communication lines. When connected to a communication system, it supports remote automation and computer-based control through substation and master station control units.
With reliable performance and a high level of automation, the CKWF-12 is widely used in substations, industrial and mining enterprises, urban and rural automated distribution networks, and other applications requiring frequent switching operations.
