Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker is a cutting-edge, three-phase AC 50Hz device boasting a rated voltage of 40.5kV. It is perfectly engineered for seamless integration into KYN61-40.5(Z) switchgear systems. This circuit breaker represents a new era of power supply and distribution equipment, crafted to deliver remarkable efficiency and unparalleled reliability in modern power infrastructure.

This sophisticated circuit breaker showcases an upper and lower structured design, adeptly minimizing the breaker's depth. Its core components, including the main conductive circuit, vacuum interrupter, and moving/static conductive connections, are elegantly encased within an insulated tube. The advanced composite insulation structure effectively isolates the three-phase arc-extinguishing chambers and related electrified components with distinct epoxy insulation casings. This ensures full compliance with air gap and creepage distance standards under standard operating conditions. All primary electrical connections are steadfastly fixed, guaranteeing exceptional reliability and extended durability.

Key Features:

1. Composite Insulation Design: Meticulously engineered to meet stringent air gap and creepage distance requirements while refining device dimensions. This layout is compact, logically organized, and visually appealing.
2. Innovative Operating Mechanism: Meticulously tailored to the unique requirements of this vacuum circuit breaker, the operating mechanism is perfectly aligned with the vacuum interrupter's characteristics, ensuring outstanding reliability, prolonged operational lifespan, and maintenance-free functionality.
3. Flexible Handcart Design: Features an intuitive screw-rod push mechanism for seamless panel insertion or withdrawal. It is enhanced with a forced mechanical interlock system to provide 'Five Prevention' functions, making it adept for diverse operational settings, including challenging conditions.
