Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker is an advanced three-phase AC 50Hz device with a rated voltage of 40.5kV. Purpose-built for seamless integration into KYN61-40.5(Z) switchgear, it represents the pinnacle of modern power supply and distribution technology. Engineered for unmatched efficiency and reliability, this next-generation circuit breaker is indispensable for contemporary power systems.

Boasting a groundbreaking upper and lower arrangement, this sophisticated circuit breaker minimizes depth for an optimized fit. Encased within an insulated tube, the main conductive circuit alongside the vacuum interrupter, and moving/static conductive connections, is designed with precision for superior performance. Its state-of-the-art composite insulation structure individually encapsulates the three-phase arc-extinguishing chambers and related electrified components, utilizing high-grade epoxy insulation casings to adhere to strict air gap and creepage distance specifications. All primary electrical connections are securely fixed, ensuring exceptional durability and reliability.

Key Features:

1. Composite Insulation Design: Masterfully engineered to fulfill stringent air gap and creepage distance standards, this design optimizes device dimensions while maintaining a sleek and rational aesthetic.
2. Innovative Operating Mechanism: This cutting-edge mechanism is tailored specifically for the vacuum circuit breaker, harmonizing with the vacuum interrupter's characteristics to deliver unparalleled reliability, an extended operational lifespan, and effortless maintenance-free service.
3. Flexible Handcart Design: Crafted with a screw-rod push mechanism, it facilitates effortless panel insertion or withdrawal. Enhanced with a robust forced mechanical interlock, it achieves comprehensive "Five Prevention" functions, making it adaptable for diverse operational environments, including the most demanding conditions.
