Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3), an advanced indoor handcart vacuum circuit breaker designed for three-phase AC systems operating at 50Hz with a rated voltage of 40.5kV. This state-of-the-art device is expertly crafted for integration into KYN61-40.5(Z) switchgear, representing a new era in power supply and distribution. Engineered for exceptional performance, it delivers unmatched efficiency and reliability tailored to modern power systems.

This sophisticated circuit breaker boasts an ingenious upper and lower structured design, significantly minimizing its overall depth. Encased within an insulated tube, the main conductive circuit, including the vacuum interrupter and moving/static conductive connections, ensures peak performance. Its groundbreaking composite insulation structure distinctly separates the three-phase arc-extinguishing chambers from electrified components using individual epoxy insulation casings, adhering to stringent air gap and creepage distance standards. All primary electrical connections are fixed to assure supreme reliability and longevity.

Key Features:

1. Composite Insulation Design: This intelligently crafted design guarantees adherence to air gap and creepage distance specifications, while optimizing the overall dimensions of the device. The layout is not only compact and logical but also visually captivating.
2. Innovative Operating Mechanism: Uniquely engineered for this vacuum circuit breaker, the mechanism aligns perfectly with the vacuum interrupter's characteristics, ensuring high reliability, an extended lifespan, and a maintenance-free experience.
3. Flexible Handcart Design: Featuring a user-friendly screw-rod push mechanism, this design facilitates effortless panel insertion or withdrawal. It's equipped with a robust mechanical interlock system delivering "Five Prevention" functions, making it adept for diverse operational environments, even under the most challenging conditions.
