It offers a full range of configurations, including economical, long-life, and high-capacity models, to suit different voltage levels and operating conditions. With long mechanical life, high reliability, maintenance-free design, and internationally compliant electrical performance, it helps power systems achieve stable and cost-effective reactive power compensation.

General description

• Product Positioning The RCS series outdoor capacitor switches from Rockwill are a new generation of vacuum switches designed for long mechanical life, primarily used for switching capacitor banks in distribution networks. The core technology combines modern manufacturing processes, computer-aided design, advanced insulation technology, and a compact structure, resulting in lightweight and small-size products.
• Longevity and Maintenance Advantages All models emphasize maintenance-free operation cycles and long mechanical life. For example, the magnetic latching type can achieve up to 100,000 mechanical operations, while spring-driven types generally reach around 10,000 operations, with some models offering several thousand to tens of thousands of maintenance-free operations. This significantly reduces maintenance costs and improves the online availability of capacitor banks.
•  Performance and Quality Assurance The products comply with multiple international and national standards (such as ANSI/IEEE C37.60, IEC 62271-100, GB1984-2003, etc.) and have passed rigorous testing to ensure reliable performance under high humidity, high pollution, and harsh climate conditions.
•  Comprehensive Benefits Using the RCS series can reduce maintenance workload, extend equipment service life, improve power quality, and lower the risk of outages caused by equipment failure.
