Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a cutting-edge three-phase AC 50Hz device with a remarkable rated voltage of 40.5kV. Tailored for integration into KYN61-40.5(Z) switchgear, this next-generation power supply and distribution equipment is engineered to deliver unparalleled efficiency and reliability, perfectly aligning with the demands of modern power systems.

This exceptional circuit breaker showcases an upper and lower arrangement design, significantly minimizing the breaker depth. The main conductive circuit, vacuum interrupter, and both moving and static conductive connections are securely encased within an insulated tube. Its pioneering composite insulation structure ensures that the three-phase arc-extinguishing chambers along with all associated electrified components are individually insulated using epoxy casings. This design meets stringent air gap and creepage distance requirements, providing top-tier reliability and durability under standard operating conditions with all primary electrical connections firmly fixed.

Key Features:

1. Composite Insulation Design: This innovative design guarantees compliance with air gap and creepage distance standards while optimizing the overall dimensions of the device. The layout is not only compact and logical but also offers an aesthetically pleasing appearance.
2. Innovative Operating Mechanism: This specially crafted mechanism is tailored to the unique characteristics of the vacuum interrupter, ensuring unmatched reliability, a prolonged operational lifespan, and maintenance-free performance.
3. Flexible Handcart Design: Features a user-friendly screw-rod push mechanism for seamless panel insertion or withdrawal. It is fortified with a robust mechanical interlock to accomplish the "Five Prevention" functions, rendering it highly suitable for a diverse range of operational environments, even in challenging conditions.
