Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker is a state-of-the-art, three-phase AC 50Hz device boasting a rated voltage of 40.5kV. Engineered for integration with KYN61-40.5(Z) switchgear, this is a pioneering advancement in power supply and distribution equipment, crafted for outstanding efficiency and unmatched reliability in cutting-edge power systems.

This circuit breaker showcases an innovative upper and lower arrangement structure, significantly minimizing the breaker's depth. The main conductive circuit, vacuum interrupter, and both moving/static conductive connections are expertly encased within an insulated tube. Its superior composite insulation structure deftly segregates the three-phase arc-extinguishing chambers from electrified components, each housed within independent epoxy insulation casings, fully compliant with air gap and creepage distance norms under standard conditions. All primary electrical connections are firmly fixed, assuring exceptional reliability and durability.

Key Features:

1. Composite Insulation Design: This design ensures rigorous compliance with air gap and creepage distance standards while achieving optimal device dimensions. The design layout is compact, intelligently structured, and visually appealing.
2. Innovative Operating Mechanism: Crafted exclusively for this vacuum circuit breaker, the operating mechanism is perfectly harmonized with the characteristics of the vacuum interrupter, delivering high reliability, an extended operational lifespan, and a maintenance-free experience.
3. Flexible Handcart Design: Features a screw-rod push mechanism that facilitates effortless panel insertion or withdrawal. Includes a robust forced mechanical interlock that implements 'Five Prevention' functions, making it adaptable to diverse operational environments, including the most challenging conditions.
