Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a state-of-the-art three-phase AC 50Hz device with a rated voltage of 40.5kV. This cutting-edge circuit breaker is extensively utilized in the KYN61-40.5(Z) switchgear, representing a new era of power supply and distribution equipment crafted for optimal efficiency and unparalleled reliability within contemporary power systems.

This innovative circuit breaker boasts an advanced upper and lower arrangement structure, significantly minimizing the breaker's depth. The main conductive circuit, vacuum interrupter, and moving/static conductive connections are ingeniously encapsulated within a high-quality insulated tube. Its sophisticated composite insulation architecture distinctly separates the three-phase arc-extinguishing chambers and their electrified counterparts using independent epoxy insulation casings. This ensures compliance with air gap and creepage distance standards under typical conditions. All primary electrical connections are securely fixed, guaranteeing superior reliability and durability throughout its lifespan.

Key Features:

1. Composite Insulation Design: This design ensures adherence to air gap and creepage distance standards while optimizing the dimensions of the device. Marvel at its compactness, logical layout, and visual appeal.
2. Innovative Operating Mechanism: Meticulously crafted for this vacuum circuit breaker, this mechanism is tailored to complement the vacuum interrupter's characteristics, providing exceptional reliability, an extended lifespan, and a maintenance-free experience.
3. Flexible Handcart Design: Featuring a screw-rod push mechanism, it allows effortless insertion or withdrawal of the panel. Equipped with a robust mechanical interlock, it fulfills the "Five Prevention" functions, rendering it ideal for diverse operational settings, including challenging environments.
