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 unit, boasting a rated voltage of 40.5kV. Engineered for installation in KYN61-40.5(Z) switchgear, this groundbreaking power supply and distribution solution is crafted to deliver unmatched efficiency and steadfast reliability, catering to the demanding needs of contemporary power systems.

This revolutionary circuit breaker showcases a pioneering upper and lower arrangement structure, significantly minimizing the breaker's depth. Encased within an insulated tube, the primary conductive circuit, vacuum interrupter, and dynamic/static conductive connections are safeguarded. Featuring an advanced composite insulation structure, it segregates the three-phase arc-extinguishing chambers and associated electrified elements using distinct epoxy insulation casings, ensuring compliance with air gap and creepage distance standards under typical conditions. With all primary electrical connections firmly secured, this design promises exceptional reliability and longevity.

Key Features:

1. Composite Insulation Design: Guarantees adherence to air gap and creepage distance standards while refining the device's dimensions. Its layout is not only compact and rational but also visually impressive.
2. Innovative Operating Mechanism: Meticulously engineered to complement the vacuum circuit breaker, this mechanism is tailored to align with the vacuum interrupter's unique traits, ensuring superior reliability, a prolonged operational life, and a truly maintenance-free experience.
3. Flexible Handcart Design: Features a sophisticated screw-rod push mechanism, facilitating effortless panel insertion or withdrawal. With a robust forced mechanical interlock, it achieves the comprehensive 'Five Prevention' functions, making it adaptable to various operational settings, even the most challenging environments.
