Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, an exceptional three-phase AC 50Hz unit engineered to handle a rated voltage of 40.5kV. Designed for seamless integration into KYN61-40.5(Z) switchgear, this state-of-the-art power supply and distribution solution is crafted to enhance efficiency and ensure unwavering reliability, perfectly suited to meet the demands of contemporary power systems.

This circuit breaker showcases an innovative upper and lower arrangement structure, significantly minimizing the breaker's depth for streamlined installation. The main conductive circuit, vacuum interrupter, and both moving and static conductive connections are securely housed within a robust insulated tube. Featuring a cutting-edge composite insulation structure, it adeptly isolates the three-phase arc-extinguishing chambers and the electrified components using independent epoxy insulation casings. This design adheres to air gap and creepage distance standards under normal conditions, guaranteeing maximum reliability and long-lasting durability through all primary electrical connections being fixed.

Key Features:

1. Composite Insulation Design: Expertly crafted to meet air gap and creepage distance standards, enhancing the device's structural dimensions. The design is both compact and rational, with an aesthetically pleasing layout that maximizes efficiency.
2. Innovative Operating Mechanism: Meticulously engineered specifically for this vacuum circuit breaker, the operating mechanism complements the characteristics of the vacuum interrupter, ensuring unmatched reliability, a remarkably extended lifespan, and a maintenance-free experience.
3. Flexible Handcart Design: Integrates a precision-engineered screw-rod push mechanism that facilitates effortless panel insertion or withdrawal. Equipped with a robust forced mechanical interlock providing 'Five Prevention' functions, this design makes it versatile for diverse operational settings, including challenging environments.
