Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

The innovative ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker stands as a pinnacle of modern engineering. This three-phase AC 50Hz powerhouse, with its rated voltage of 40.5kV, seamlessly integrates into KYN61-40.5(Z) switchgear. Designed as a new generation of power supply and distribution equipment, it is crafted for outstanding efficiency and unwavering reliability in contemporary power systems.

Our circuit breaker's innovative upper and lower arrangement significantly reduces its depth, ensuring a sleek profile. Enclosed within an insulated tube, the main conductive circuit, vacuum interrupter, and both moving and static conductive connections are meticulously organized. Featuring an advanced composite insulation structure, it offers precise separation of the three-phase arc-extinguishing chambers and electrified components via independent epoxy insulation casings. This thoughtful design adheres to stringent air gap and creepage distance standards under normal conditions, achieving unparalleled reliability and durability.

Key Features:

1. Composite Insulation Design: Elegantly balances form and function, ensuring adherence to air gap and creepage distance standards while optimizing dimensions. The layout is not only compact but also rational and visually harmonious.
2. Innovative Operating Mechanism: Specifically tailored for this vacuum circuit breaker, the operating mechanism aligns perfectly with the vacuum interrupter's characteristics. It promises exceptional reliability, a long operational lifespan, and a maintenance-free experience.
3. Flexible Handcart Design: Features a sophisticated screw-rod push mechanism for effortless panel insertion or withdrawal. Complete with a robust mechanical interlock, it ensures comprehensive "Five Prevention" functions, adeptly handling varied operational environments, even under challenging conditions.
