Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a pinnacle of modern engineering in power distribution, designed specifically for three-phase AC 50Hz systems. Boasting a rated voltage of 40.5kV, this state-of-the-art equipment integrates seamlessly within KYN61-40.5(Z) switchgear. Crafted for the utmost efficiency and dependability, it represents a new era in power supply and distribution technology, ensuring superior performance and safety in today's advanced power infrastructures.

This innovative circuit breaker showcases a unique upper and lower arrangement structure, dramatically reducing the device's depth. Encased within an insulated tube are the main conductive circuit, vacuum interrupter, and static/moving conductive connections. Its sophisticated composite insulation structure distinctly isolates the three-phase arc-extinguishing chambers and associated electrified components. Each is secured with independent epoxy insulation casings, meticulously adhering to air gap and creepage distance standards under ordinary conditions. Each primary electrical connection is fixed with precision, guaranteeing exceptional reliability and longevity.

Key Features:

1. Composite Insulation Design: This design ensures adherence to stringent air gap and creepage distance standards while optimizing the dimensions of the device. The layout not only maximizes functionality but also presents a compact, rational, and visually appealing aesthetic, enhancing both performance and appearance.
2. Innovative Operating Mechanism: Meticulously engineered specifically for this vacuum circuit breaker, the operating mechanism aligns perfectly with the vacuum interrupter's characteristics. It promises unrivaled reliability, an impressive lifespan, and a maintenance-free experience, providing peace of mind and enduring performance.
3. Flexible Handcart Design: Features a sophisticated screw-rod push mechanism for effortless panel insertion or withdrawal. Enhanced with a robust mechanical interlock, it achieves the "Five Prevention" safety functions, making it exceptionally adaptable for diverse operational environments, even in the most challenging conditions.
