Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a state-of-the-art three-phase AC 50Hz device, crafted with precision for a rated voltage of 40.5kV. Its integration into KYN61-40.5(Z) switchgear symbolizes the pinnacle of power supply and distribution innovation, delivering unparalleled high efficiency and reliability tailored to modern power systems.

This advanced circuit breaker boasts a unique upper and lower arrangement structure that significantly minimizes the breaker depth. Enclosed within an insulated tube, you will find the main conductive circuit, vacuum interrupter, and dynamic/static conductive connections meticulously engineered to perfection. Its cutting-edge composite insulation structure ingeniously isolates the three-phase arc-extinguishing chambers and related electrified components with dedicated epoxy insulation casings, adhering to stringent air gap and creepage distance standards under normal conditions. With all primary electrical connections firmly fixed, it guarantees exceptional reliability and longevity.

Key Features:

1. Composite Insulation Design: Masterfully ensures adherence to air gap and creepage distance requisites, while ingeniously optimizing device dimensions. Its layout is not only compact and logically organized but also exudes aesthetic elegance.
2. Innovative Operating Mechanism: Crafted uniquely for this vacuum circuit breaker, the mechanism is perfectly aligned with the vacuum interrupter's attributes, assuring outstanding reliability, a prolonged lifespan, and a maintenance-free experience.
3. Flexible Handcart Design: Featuring a sophisticated screw-rod push system for seamless panel integration or removal, it is equipped with an advanced mechanical interlock for 'Five Prevention' functionalities, adapting effortlessly to diverse operational environments, including extreme conditions.
