Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a marvel of modern engineering designed for three-phase AC 50Hz systems with an impressive rated voltage of 40.5kV. Seamlessly integrated into the KYN61-40.5(Z) switchgear, this cutting-edge breaker represents a new generation of power supply and distribution equipment tailored for maximum efficiency and reliability in today's advanced power systems.

This innovative circuit breaker boasts an upper and lower arrangement structure that notably reduces its depth. Encapsulated within an insulated tube, the main conductive circuit, vacuum interrupter, and moving/static conductive connections are expertly housed. Its pioneering composite insulation structure diligently separates the three-phase arc-extinguishing chambers and associated electrified components with independent epoxy insulation casings, flawlessly meeting air gap and creepage distance requirements under normal operational conditions. In addition, all primary electrical connections are firmly secured, ensuring unparalleled reliability and lasting durability.

Key Features:

1. Composite Insulation Design: This design guarantees adherence to air gap and creepage distance standards while optimizing device size. The layout is not only compact and efficient but also visually striking.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, the mechanism perfectly complements the vacuum interrupter's characteristics, delivering superior reliability and a prolonged lifespan with a promise of maintenance-free operation.
3. Flexible Handcart Design: Featuring a screw-rod push mechanism, this design allows for effortless panel insertion or removal. It is equipped with a robust mechanical interlock to implement the "Five Prevention" functions, making it adaptable to diverse operational settings, even in challenging conditions.
