Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker - a marvel in modern technology! This state-of-the-art three-phase AC 50Hz device operates at a rated voltage of 40.5kV, and is the latest innovation in the realm of power supply and distribution equipment. Engineered for robust performance and stellar reliability, this breaker is seamlessly integrated into KYN61-40.5(Z) switchgear, setting a new benchmark for high-efficiency power systems.

Revolutionary in design, this circuit breaker boasts an innovative upper and lower arrangement structure that ingeniously minimizes depth. It encases the main conductive circuit, vacuum interrupter, and both moving/static conductive connections within a meticulously crafted insulated tube. With an advanced composite insulation architecture, it expertly separates the three-phase arc-extinguishing chambers from the electrified components using independent epoxy insulation. This ensures compliance with air gap and creepage distance standards under standard operating conditions, promising unparalleled reliability and longevity in its electrical connections.

Key Features:

1. Composite Insulation Design: Meticulously crafted to meet stringent air gap and creepage distance specifications, while also optimizing device dimensions. This compact, well-thought-out layout is not only technically superior but also visually appealing.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, the operating mechanism aligns perfectly with the vacuum interrupter's characteristics. It guarantees unparalleled reliability, an extended operational lifespan, and a truly maintenance-free experience.
3. Flexible Handcart Design: Features an ingeniously designed screw-rod push mechanism simplifying panel insertion and withdrawal. Equipped with a robust forced mechanical interlock, it provides comprehensive 'Five Prevention' functions, making it ideally suited for diverse operational environments, including the toughest conditions.
