Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a three-phase AC 50Hz powerhouse with a rated voltage of 40.5kV. This cutting-edge device is seamlessly integrated into KYN61-40.5(Z) switchgear, representing the pinnacle of power supply and distribution innovation. Crafted to excel in modern power systems, it ensures unparalleled efficiency and reliability, setting a new standard in electrical excellence.

This advanced circuit breaker boasts an upper and lower arrangement structure, skillfully minimizing the breaker's depth. Encased within an insulated tube, the main conductive circuit, vacuum interrupter, and moving/static conductive connections are expertly housed. The sophisticated composite insulation structure distinctly separates the three-phase arc-extinguishing chambers and associated electrified components with independent epoxy insulation casings. This ensures compliance with air gap and creepage distance norms under standard conditions. The primary electrical connections are steadfastly fixed, promising exceptional reliability and longevity.

Key Features:

1. Composite Insulation Design: This design not only adheres to air gap and creepage distance standards but also optimizes device dimensions, presenting a compact, rational, and visually appealing layout.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, the mechanism aligns flawlessly with the vacuum interrupter's properties, offering exceptional reliability, prolonged lifespan, and maintenance-free operation.
3. Flexible Handcart Design: Features a screw-rod push mechanism that facilitates effortless panel insertion or withdrawal. The inclusion of a forced mechanical interlock ensures comprehensive 'Five Prevention' functions, making it adaptable for diverse operational environments, including the most challenging conditions.
