Introducing the ZW7-40.5kV Series Outdoor H.V. VCB - the ultimate electrical appliance equipment for all your power needs! With its tri-phase AC 50Hz and rated voltage of 40.5kV, this high-voltage circuit breaker is a force to be reckoned with. Equipped with both spring operation mechanism and electromagnetism operation mechanism, it offers the convenience of far control electrically operated opening and closing, as well as the option for manual energy storage and manual opening and closing. Talk about versatility!
But that's not all - the design performance of the ZW7-40.5kV VCB meets the requirements of both the national standard GB1984 AC H.V. Circuit Breaker and the IEC standard IEC-65 High Voltage AC Circuit Breaker. So you can rest assured that you're getting a top-notch product that adheres to the highest industry standards.
Now, let's talk about its applications. The ZW7-40.5kV vacuum circuit breaker is specifically designed for outdoor use in 40.5kV power transformer systems. It's perfect for control and protection purposes, making it an ideal choice for normal operation and short circuit protection in city and township power distribution networks, as well as in various industries and mining enterprises. This circuit breaker is truly a game-changer!
When it comes to structure, the ZW7-40.5kV VCB boasts a porcelain insulator column type design. The upper porcelain insulator houses the vacuum interrupter, while the lower porcelain insulator serves as the prop porce. This thoughtful design ensures optimal performance and durability.
