Product Description
1. PRODUCT OVERVIEWThe FRZW32 Series outdoor high-voltage vacuum circuit breaker is an engineering marvel with its uniquely designed integrated solid-sealed pole and highly reliable operating mechanism. This innovative device is meticulously crafted for medium-voltage overhead power lines, expertly handling the switching, connection of load currents, as well as managing overload and short-circuit currents with precision. It is ideal for deployment in substations, industrial complexes, mining sectors' power distribution networks, and rural power grids necessitating frequent operations-offering robust protection and sophisticated control.
♦ Exceptionally high reliability for peace of mind
♦ Absolutely maintenance-free throughout its operational life
♦ Offers an impressive mechanical and electrical lifespan
♦ Compact, lightweight design ensures effortless installation2. USAGE CONDITIONS
♦ Suitable ambient air temperature: from a brisk -30ºC to a warm +60ºC;
♦ Operational altitude should not exceed 3000 meters;
♦ Can withstand wind speeds up to 34m/s without compromise;
♦ Designed to withstand vibrations or seismic activity from external switch and control devices, which can be ignored;
♦ Endures a pollution level rated at Grade IV;
♦ Storage-friendly withstanding temperatures from -40ºC to a scorching +85ºC3. PRODUCT FEATURE♦ Advanced intelligent control function: Not only does it feature on-site switch status control, three-stage overcurrent protection, and automatic reclosing, but it also boasts an RS-485 communication interface for seamless remote telemetry, adjustment, control, and signaling. Perfect for a range of automated distribution systems.
♦ State-of-the-art permanent magnet operating mechanism: Utilizing the latest in permanent magnet technology, this circuit breaker experiences zero component wear, extending its mechanical life to an impressive 3000 cycles-three times more than conventional spring mechanisms. With a 70% reduction in mechanical parts compared to spring mechanisms, reliability is significantly enhanced.
♦ Ingenious fully sealed structure design: The vacuum arc-extinguishing chamber, along with its operating mechanism and linkage, is securely sealed within the base-eliminating condensation issues that cause rust, achieving maintenance-free performance for an astonishing 10 years.
♦ Innovative compact structure: Featuring a new type of composite solid insulation material, integrating the vacuum arc-extinguishing chamber, main conductive circuit, and insulation support into a cohesive sealed pole. This inventive design resolves the challenge of miniaturization while meeting external insulation standards, resulting in an advanced, compact, and robust product structure.4. PARAMETERS
