Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the state-of-the-art ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a pinnacle of modern engineering excellence. Operating at a three-phase AC 50Hz with a rated voltage of 40.5kV, it is the heart of the KYN61-40.5(Z) switchgear. This revolutionary power supply and distribution marvel is crafted for high performance and unwavering reliability, setting a new standard in contemporary power systems.

This innovative circuit breaker boasts a unique upper and lower arrangement, significantly reducing the device's depth for optimal space utilization. Encased within an insulated tube are the main conductive circuit, vacuum interrupter, and moving/static conductive connections, providing a robust and efficient solution. Its cutting-edge composite insulation structure ensures each of the three-phase arc-extinguishing chambers and their electrified components are distinctly separated by independent epoxy insulation casings. Designed to meet stringent air gap and creepage distance standards, all primary electrical connections are securely fixed, promising exceptional reliability and longevity.

Key Features:

  1. Composite Insulation Design: Delivering unparalleled compliance with air gap and creepage distance standards, this design not only optimizes dimensions but also offers a compact, well-organized, and visually appealing layout.
  2. Innovative Operating Mechanism: Meticulously crafted for this vacuum circuit breaker, this mechanism aligns seamlessly with the vacuum interrupter's specifications, ensuring remarkable reliability, longevity, and a maintenance-free experience.
  3. Flexible Handcart Design: Equipped with a screw-rod push mechanism, it allows effortless insertion or withdrawal of the panel, fortified with a forced mechanical interlock that supports the 'Five Prevention' functions. This makes it highly adaptable to varied operational environments, including the most challenging conditions.
