Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) Indoor Handcart Vacuum Circuit Breaker, a marvel of modern engineering! This three-phase AC 50Hz device is crafted with precision for a rated voltage of 40.5kV, making it an indispensable component in KYN61-40.5(Z) switchgear. Our circuit breaker embodies the new generation of power supply and distribution technology, designed to deliver unparalleled efficiency and reliability, perfectly aligned with the demands of contemporary power systems.

Our innovative circuit breaker is distinguished by its upper and lower arrangement structure that ingeniously minimizes the breaker’s depth. The core components, including the main conductive circuit, vacuum interrupter, and both moving and static conductive connections, are securely encased within a robust insulated tube. The breakthrough composite insulation structure expertly separates the three-phase arc-extinguishing chambers and their electrified components using exclusive epoxy insulation casings. This ensures compliance with air gap and creepage distance specifications under standard operating conditions, offering unmatched reliability and longevity in every primary electrical connection which is firmly fixed to guarantee seamless performance.

Key Features:

1. Composite Insulation Design: This design is a testament to engineering brilliance, meeting air gap and creepage distance standards while enhancing the product's dimensions. The layout is not only compact and functional but also exudes a sophisticated, aesthetically pleasing appeal.
2. Innovative Operating Mechanism: Specifically crafted for our vacuum circuit breaker, this operating mechanism is attuned to the unique properties of the vacuum interrupter. It promises exceptional reliability, an extended service life, and the added benefit of being maintenance-free, ensuring peace of mind and consistent performance.
3. Flexible Handcart Design: This design incorporates a screw-rod push mechanism that facilitates effortless panel insertion or withdrawal. With a powerful forced mechanical interlock system, it accomplishes the 'Five Prevention' functions, making it ideal for diverse operational environments, including the most challenging conditions.
