Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the sophisticated ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker—a powerful and dependable three-phase AC 50Hz device with a rated voltage of 40.5kV. Expertly engineered for integration into the KYN61-40.5(Z) switchgear, this cutting-edge breaker represents a new wave of power supply and distribution technology. It sets the standard for high efficiency and unmatched reliability in contemporary power systems, ensuring seamless operations.

With its state-of-the-art upper and lower arrangement structure, this circuit breaker minimizes the depth, improving installation flexibility. The main conductive circuit, vacuum interrupter, and both moving and static conductive connections are innovatively encased within an insulated tube. Its advanced composite insulation architecture distinctly segregates the three-phase arc-extinguishing chambers and associated electrified components, wrapped in individual epoxy insulation casings. This design adheres to air gap and creepage distance standards under standard conditions, guaranteeing exceptional reliability and robustness with all primary electrical connections securely fixed.

Key Features:

1. Composite Insulation Design: Tailored to comply with air gap and creepage distance standards, while smartly optimizing dimensions for a compact, rational, and visually appealing layout.
2. Innovative Operating Mechanism: Meticulously crafted for the vacuum circuit breaker, this mechanism aligns perfectly with the vacuum interrupter's characteristics, delivering unparalleled reliability, an extended service life, and maintenance-free performance.
3. Flexible Handcart Design: Features a screw-rod push mechanism for effortless insertion or removal from the panel. Equipped with a robust mechanical interlock to enable "Five Prevention" functions, it is adaptable to a wide range of operational settings, including demanding environments.
