Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker stands as a pinnacle of engineering in three-phase AC 50Hz devices, boasting a rated voltage of 40.5kV. This cutting-edge system finds its extensive application in KYN61-40.5(Z) switchgear, emerging as a next-generation marvel in power supply and distribution. Designed to deliver exceptional efficiency and steadfast reliability, it adeptly meets the demands of modern power systems.

This circuit breaker is ingeniously crafted with an upper and lower arrangement, significantly minimizing its depth. Encased within an insulated tube are the primary conductive circuit, vacuum interrupter, and moving/static conductive connections. Its pioneering composite insulation structure distinctly separates the three-phase arc-extinguishing chambers and associated electrified elements using independent epoxy insulation casings. This design not only meets but excels the standard air gap and creepage distance requirements. The fixed design of all primary electrical connections assures unparalleled reliability and longevity.

Key Features:

1. Composite Insulation Design: This design is meticulously crafted to ensure compliance with stringent air gap and creepage distance standards while maintaining a compact and efficient form. The layout is strategically optimized for functionality and visual appeal.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, this mechanism perfectly aligns with the characteristics of the vacuum interrupter, delivering unmatched reliability, an extended lifespan, and a promise of maintenance-free operation.
3. Flexible Handcart Design: Featuring a sophisticated screw-rod push mechanism, this design facilitates effortless insertion or withdrawal from panels. The incorporation of a robust forced mechanical interlock ensures comprehensive 'Five Prevention' capabilities, making this design adept for diverse operational settings, even under challenging conditions.
