Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the revolutionary ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a pinnacle of advanced engineering. Designed for three-phase AC 50Hz operations and boasting a rated voltage of 40.5kV, this breaker is a critical component in the KYN61-40.5(Z) switchgear. It exemplifies a new era of power supply and distribution equipment, crafted for unmatched efficiency and reliability in cutting-edge power systems.

Engineered with a sophisticated upper and lower arrangement, this circuit breaker significantly reduces its depth, optimizing spatial efficiency. Within an insulated tube, the main conductive circuit, vacuum interrupter, and static conductive connections are meticulously housed. Its pioneering composite insulation structure ensures that the three-phase arc-extinguishing chambers and electrified components are independently encased in epoxy insulation, adhering to stringent air gap and creepage distance standards for outstanding reliability and robustness.

Key Features:

1. Composite Insulation Design: This design guarantees compliance with all necessary air gap and creepage distance specifications while maximizing the device's compactness. The layout is not only efficient but also exudes a sense of modern elegance.
2. Innovative Operating Mechanism: Crafted specifically for this vacuum circuit breaker, the operating mechanism is perfectly synchronized with the vacuum interrupter's characteristics, offering unparalleled reliability, a remarkable lifespan, and maintenance-free operation, redefining industry standards.
3. Flexible Handcart Design: Featuring a user-friendly screw-rod push mechanism, this design allows effortless panel insertion or withdrawal. The robust forced mechanical interlock ensures the "Five Prevention" functions, making it adaptable to a wide range of operational environments, including challenging conditions with ease.
