Product Description
1. PRODUCT OVERVIEWThe FRZW32 Series outdoor high-voltage vacuum circuit breaker is an engineering marvel that combines a one-of-a-kind integrated solid-sealed pole with an exceptionally reliable operating mechanism. Designed to serve medium-voltage overhead power lines, it excels in switching, connecting load currents, and handling both overload and short-circuit currents with precision. Perfectly suited for substations, industrial and mining enterprises' power distribution systems, as well as rural power grids where frequent operations are necessary, it offers unparalleled protection and control.
♦ Unmatched reliability ensuring peace of mind.
♦ Designed to be maintenance-free throughout its impressive lifespan, providing cost efficiency.
♦ Boasts a long mechanical and electrical lifespan for enduring performance.
♦ Its compact and lightweight design ensures effortless installation.2. USAGE CONDITIONS
♦ Ambient air temperature ranges comfortably from -30ºC to +60ºC, accommodating diverse climatic conditions.
♦ Operable at altitudes up to 3000 meters, adapting to high-altitude environments.
♦ Can withstand wind speeds up to 34 m/s, perfect for challenging weather.
♦ Resilient to vibrations and seismic activities from external devices-contributing to its robust stability.
♦ Rated at a Pollution level: Grade IV, designed for environments with higher pollution levels.
♦ Storage temperature ranges from -40ºC to +85ºC, ensuring safe preservation.3. PRODUCT FEATURE♦ Equipped with an intelligent control function, it not only provides on-site switch status control but also offers three-stage overcurrent protection and automatic reclosing. The RS-485 communication interface expands its capabilities with remote telemetry, adjustment, control, and signaling, making it ideal for automated distribution systems of any scale.
♦ Utilizes a state-of-the-art permanent magnet operating mechanism with zero component wear, extending the mechanical life to a remarkable 3000 operations-three times that of traditional spring mechanisms. With a 70% reduction in mechanical parts, it elevates switch reliability significantly.
♦ Its fully sealed structure design encloses the vacuum arc-extinguishing chamber, operating mechanism, and linkage, eliminating condensation issues and preventing rust, achieving maintenance-free operation for a decade.
♦ The compact structure features an innovative composite solid insulation material, integrating the vacuum arc-extinguishing chamber, main circuit, and insulation support into a unified sealed pole. This resolves the challenge of miniaturization while maintaining external insulation standards, featuring a progressive and compact design with no internal condensation or mechanism rust.4.
