Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker—an epitome of modern engineering and innovation. Designed with precision for three-phase AC 50Hz systems and a rated voltage of 40.5kV, it is seamlessly integrated into KYN61-40.5(Z) switchgear. This groundbreaking power supply and distribution solution promises to elevate efficiency and reliability across contemporary power networks.

This state-of-the-art circuit breaker boasts a unique upper and lower arrangement structure, which significantly minimizes the depth of the breaker. Enclosed within an insulated tube, its main conductive circuit, vacuum interrupter, and moving and static conductive connections are meticulously organized. Its sophisticated composite insulation design demarcates the three-phase arc-extinguishing chambers and electrified components using independent epoxy insulation casings, effortlessly meeting air gap and creepage distance standards under typical conditions. With all primary electrical connections securely fixed, it assures exceptional reliability and durability.

Key Features:

1. Composite Insulation Design: Crafted to comply with stringent air gap and creepage distance standards while optimizing device dimensions. The configuration is compact, well-organized, and visually appealing.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, the mechanism aligns seamlessly with the vacuum interrupter's characteristics, ensuring unmatched reliability, an extended lifespan, and maintenance-free operation.
3. Flexible Handcart Design: Features a screw-rod push mechanism for effortless panel maneuvering, whether insertion or withdrawal. It is fortified with a robust mechanical interlock to guarantee the "Five Prevention" functions, making it adaptable for diverse operational settings, including challenging environments.
