Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3), a state-of-the-art indoor handcart vacuum circuit breaker designed to meet the demanding needs of modern electrical systems. Operating at a three-phase AC 50Hz with a rated voltage of 40.5kV, this cutting-edge apparatus is engineered for seamless integration with KYN61-40.5(Z) switchgear. As a pinnacle of innovation and technology, it represents the new frontier in power supply and distribution equipment, delivering unparalleled efficiency and reliability for contemporary power infrastructures.

This innovative circuit breaker is crafted with an ingenious upper and lower arrangement structure, significantly enhancing its spatial efficiency by minimizing depth. Encased within a robust insulated tube lies the main conductive circuit, vacuum interrupter, and the dynamic/static conductive junctions. Its state-of-the-art composite insulation design distinguishes the three-phase arc-extinguishing chambers while safeguarding electrified components using independent epoxy insulation housings. This meticulous architecture ensures adherence to air gap and creepage distance standards, promising exceptional reliability and longevity for all primary electrical connections.

Key Features:

1. Composite Insulation Design: Achieves optimal compliance with air gap and creepage distance standards, all while refining the device's dimensions. The design is both compact and rational, presenting a visually appealing aesthetic.
2. Innovative Operating Mechanism: Uniquely engineered for compatibility with this vacuum circuit breaker, the mechanism aligns perfectly with the vacuum interrupter's specific attributes, delivering superior reliability, a prolonged operational lifespan, and an entirely maintenance-free experience.
3. Flexible Handcart Design: Features a user-friendly screw-rod push mechanism allowing for effortless panel insertion or removal. Equipped with a robust mechanical interlock system to implement "Five Prevention" functions, this design ensures adaptability across diverse operational environments, even under the most challenging conditions.
