Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the cutting-edge ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, meticulously engineered for three-phase AC systems operating at 50Hz with a robust rated voltage of 40.5kV. This state-of-the-art device finds its optimal application in KYN61-40.5(Z) switchgear, representing the pinnacle of innovation for contemporary power supply and distribution. Engineered with precision, it delivers unmatched efficiency and reliability, tailored to meet the demands of modern, high-performance power infrastructures.

The ingenuity of this circuit breaker lies in its strategic upper and lower arrangement structure, significantly minimizing the depth for streamlined installation. Encased within an insulated tube, the primary conductive circuit, vacuum interrupter, and dynamic/static conductive connections are expertly integrated. With a revolutionary composite insulation structure, the device ensures independent epoxy insulation casings for each of the three-phase arc-extinguishing chambers, achieving compliance with air gap and creepage distance norms under standard operating conditions. The fixed nature of all primary electrical connections guarantees exceptional reliability and durability, making it a dependable choice for professionals.

Key Features:

1. Composite Insulation Design: This innovative design not only meets air gap and creepage distance specifications but also optimizes the device's dimensions for a sleek, compact, and visually appealing layout.
2. Innovative Operating Mechanism: Tailored exclusively for this vacuum circuit breaker, the advanced mechanism is synchronized with the vacuum interrupter's dynamics, ensuring superior reliability, a prolonged lifespan, and maintenance-free performance.
3. Flexible Handcart Design: Featuring a sophisticated screw-rod push mechanism, this design facilitates seamless panel insertion or withdrawal. Augmented with a rigorous mechanical interlock, it executes "Five Prevention" functions effortlessly, making it adaptable to diverse operational environments, including the most challenging of conditions.
