Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Step into the future of power management with the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a cutting-edge three-phase AC 50Hz apparatus engineered with a rated voltage of 40.5kV. Expertly integrated into KYN61-40.5(Z) switchgear, this state-of-the-art breaker is the epitome of modern power supply and distribution technology, delivering unparalleled efficiency and reliability tailored for the demands of contemporary power systems.

This revolutionary circuit breaker boasts an innovative upper and lower arrangement, significantly minimizing the breaker’s depth for a streamlined profile. Encasing the main conductive circuit, vacuum interrupter, and conductive connections within a robust insulated tube, it exemplifies engineering brilliance. Featuring an advanced composite insulation structure, it effectively segregates the three-phase arc-extinguishing chambers and their electrified components with epoxy insulation casings, ensuring strict adherence to air gap and creepage distance standards. All primary electrical connections are securely fixed, maximizing reliability and longevity.

Key Features:

1. Composite Insulation Design: Meticulously crafted to satisfy air gap and creepage distance prerequisites while enhancing the device's dimensions for a compact, logical, and visually appealing layout.
2. Innovative Operating Mechanism: This specialized mechanism, crafted exclusively for this vacuum circuit breaker, aligns seamlessly with the vacuum interrupter’s characteristics, offering unmatched reliability, a prolonged service life, and the luxury of maintenance-free operation.
3. Flexible Handcart Design: Employs a sophisticated screw-rod push mechanism to facilitate effortless panel insertion or removal. Augmented with a robust mechanical interlock, it achieves 'Five Prevention' functions, making it ideal for varied operational scenarios, even in demanding environments.
