Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

The groundbreaking ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker sets a new standard in electrical solutions. Operating at a three-phase AC 50Hz and with an impressive rated voltage of 40.5kV, it seamlessly integrates into KYN61-40.5(Z) switchgear. This state-of-the-art power supply and distribution marvel is crafted for optimal efficiency and unparalleled reliability, serving as a cornerstone in the advancement of modern power systems.

By featuring an ingenious upper and lower arrangement, this circuit breaker expertly minimizes depth without compromising performance. Encased within an insulating tube, the main conductive circuit, vacuum interrupter, and moving/static conductive connections are brilliantly organized. The advanced composite insulation architecture ensures each phase of the arc-extinguishing chamber and its electrified components have independent epoxy insulation casings, strictly adhering to air gap and creepage distance benchmarks. This design guarantees fixed primary electrical connections, delivering exceptional reliability and longevity.

Key Features:

1. Composite Insulation Design: A masterful compliance with air gap and creepage distance specifications, this design streamlines device dimensions while maintaining a compact, logically structured, and visually appealing layout.
2. Innovative Operating Mechanism: Specifically crafted for this vacuum circuit breaker, the mechanism harmonizes with the vacuum interrupter's traits, resulting in remarkable reliability, a significantly prolonged lifespan, and operation that is blissfully maintenance-free.
3. Flexible Handcart Design: Utilizes a precision screw-rod push mechanism for seamless panel engagement or withdrawal. The robust mechanical interlock is engineered to achieve essential 'Five Prevention' functions, rendering it adaptable to a multitude of operational environments, including those with severe conditions.
