Product Description
1. PRODUCT OVERVIEWThe FRZW32 Series outdoor high-voltage vacuum circuit breaker is a masterpiece of engineering, featuring a uniquely designed integrated solid-sealed pole and a highly reliable operating mechanism. This exceptional device is primarily deployed in medium-voltage overhead power lines, skillfully managing the switching, connection of load currents, handling overload currents, and mitigating short-circuit currents with remarkable efficiency and precision. Ideally suited for deployment in substations, industrial and mining enterprises' power distribution systems, as well as rural power grids demanding frequent operations, this circuit breaker is an essential asset for ensuring protection and control.
♦ Boasts remarkably high reliability
♦ Offers an entirely maintenance-free experience for its entire lifespan
♦ Impressively high mechanical and electrical lifespan
♦ Features a compact size and lightweight design, simplifying installation.2. USAGE CONDITIONS
♦ Ambient air temperature resiliently ranges from -30ºC to +60ºC;
♦ Operates effectively at altitudes not exceeding 3000 meters;
♦ Capable of withstanding wind speeds up to 34m/s;
♦ Unaffected by vibrations or seismic activities from external switch and control devices;
♦ Endures pollution up to Grade IV;
♦ Efficient storage temperature between -40ºC and +85ºC3. PRODUCT FEATURE♦ Intelligent control function: Beyond traditional on-site switch status control, this circuit breaker excels with three-stage overcurrent protection and automatic reclosing. Its RS-485 communication interface empowers remote telemetry, remote adjustment, remote control, and remote signaling, seamlessly integrating into various scales of automated distribution systems.
♦ Permanent magnet operating mechanism: This circuit breaker incorporates the most advanced permanent magnet operating mechanism, ensuring zero wear on components. Its mechanical life extends to an impressive 3000 operations, tripling the lifespan of ordinary spring mechanisms. With a 70% reduction in mechanical parts compared to spring mechanisms, it significantly enhances switch reliability.
♦ Fully sealed structure design: The vacuum arc-extinguishing chamber, operating mechanism, and linkage are completely sealed within the base, eliminating condensation-induced rust. This innovative design ensures maintenance-free operation for an outstanding period of up to 10 years.
♦ Compact structure: Utilizing a cutting-edge composite solid insulation material, this circuit breaker integrates the vacuum arc-extinguishing chamber, main conductive circuit, and insulation support into a unified sealed pole. It masterfully resolves the challenge of miniaturization while adhering to external insulation standards. The design exemplifies advanced ingenuity with a compact, condensation-free, and rust-resistant structure.4. PARAMETERS
