Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the revolutionary ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a cutting-edge three-phase AC device operating at 50Hz with an impressive rated voltage of 40.5kV. Seamlessly integrated into KYN61-40.5(Z) switchgear, this marvel epitomizes the next generation of power supply and distribution solutions, crafted with precision for unmatched efficiency and reliability in contemporary power systems.

Designed with a sophisticated upper and lower arrangement, this circuit breaker minimizes depth while enhancing functionality. The heart of the device—the main conductive circuit, vacuum interrupter, and moving/static conductive connections—resides within a fortified insulated tube. Its state-of-the-art composite insulation structure isolates the three-phase arc-extinguishing chambers, alongside electrified components, using distinct epoxy insulation casings. This ensures optimal compliance with air gap and creepage distance standards under normal conditions. With all primary electrical connections securely fixed, it promises superior reliability and enduring performance.

Key Features:

1. Composite Insulation Design: Masterfully engineered to adhere to air gap and creepage distance guidelines, this design optimizes device dimensions while presenting a compact, logical, and visually appealing layout.
2. Innovative Operating Mechanism: Tailored exclusively for this vacuum circuit breaker, the mechanism is harmonized with the vacuum interrupter's traits, delivering exceptional reliability, a prolonged lifespan, and zero-maintenance operation.
3. Flexible Handcart Design: Features an intuitive screw-rod push mechanism for effortless panel integration or removal. Equipped with a robust mechanical interlock system to perform "Five Prevention" functions, it is engineered to excel in diverse operational environments, including the most challenging conditions.
