Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor vacuum circuit breaker, a state-of-the-art three-phase AC 50Hz system boasting a rated voltage of 40.5kV. This cutting-edge technology is adeptly integrated within the KYN61-40.5(Z) switchgear, marking a revolution in power supply and distribution. Perfectly engineered for maximum efficiency and dependable performance, it stands as an indispensable asset in the realm of contemporary power systems.

The circuit breaker showcases an innovative upper and lower arrangement, significantly minimizing depth. Encased within a robust insulated tube, the main conductive circuit, vacuum interrupter, and dynamic/static connections are expertly organized. Its superior composite insulation structure artfully segregates the three-phase arc-extinguishing chambers and electrified elements with independent epoxy insulation casings, meeting stringent air gap and creepage distance standards. Every primary electrical connection is meticulously fixed, assuring unparalleled reliability and longevity.

Key Features:

1. Composite Insulation Design: Masterfully engineered to adhere to air gap and creepage distance protocols while optimizing device dimensions. Its layout is not only compact and rational but also visually striking.
2. Innovative Operating Mechanism: This exclusive mechanism, crafted specifically for the vacuum circuit breaker, perfectly aligns with the vacuum interrupter's unique characteristics, delivering unmatched reliability, an extended lifespan, and a hassle-free, maintenance-free operation.
3. Flexible Handcart Design: Features a screw-rod push mechanism, simplifying panel insertion or withdrawal. Augmented by a forced mechanical interlock, it proficiently achieves the 'Five Prevention' functions, ensuring adaptability to diverse operational environments, including the most challenging conditions.
