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 electrical engineering with a three-phase AC 50Hz configuration and a rated voltage of 40.5kV. Exceptionally crafted for integration within KYN61-40.5(Z) switchgear, this circuit breaker represents the pinnacle of innovation in power supply and distribution systems. Its design ensures high efficiency and steadfast reliability, perfectly aligning with the demands of contemporary power infrastructures.

Meticulously engineered, this circuit breaker boasts an upper and lower arrangement structure, cleverly minimizing the device's depth. Nestled within an insulated tube, the main conductive circuit, vacuum interrupter, and both the moving and static conductive connections are harmoniously combined. The advanced composite insulation structure elegantly separates each phase's arc-extinguishing chambers and their electrified components, all encased in robust, independent epoxy insulation casings. It meets stringent air gap and creepage distance standards, ensuring unparalleled reliability and longevity.

Key Features:

1. Composite Insulation Design: This state-of-the-art design not only adheres to air gap and creepage distance regulations but also optimizes the device's dimensions. The result is a layout that is compact yet elegantly rational, bringing an aesthetic allure to its robust functionality.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, the mechanism aligns seamlessly with the vacuum interrupter's characteristics. This synergy ensures exceptional reliability, a prolonged operational lifespan, and a maintenance-free experience.
3. Flexible Handcart Design: Featuring a sophisticated screw-rod push mechanism, it allows for effortless panel insertion or removal. The robust mechanical interlock delivers the 'Five Prevention' functions, enhancing versatility across diverse operational conditions, including the most challenging environments.
