Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the cutting-edge ZN85-40.5/T(3AV3), an indoor handcart vacuum circuit breaker that harnesses three-phase AC 50Hz technology with a rated voltage of 40.5kV. This state-of-the-art device, integral to KYN61-40.5(Z) switchgear systems, represents the pinnacle of next-generation power supply and distribution equipment. Designed with modern power system demands in mind, it offers unparalleled efficiency and reliability.

Experience superior innovation with this circuit breaker's dual-level arrangement, which ingeniously reduces its depth. Encased within an insulated tube are the main conductive circuit, vacuum interrupter, and moving/static conductive connections, all beautifully aligned. Its advanced composite insulation design intelligently separates the three-phase arc-extinguishing chambers and utilizes robust epoxy insulation casings for the associated electrified components. This ensures precise air gap and creepage distance compliance, promising high reliability and durability with all primary electrical connections securely fixed.

Key Features:

1. Composite Insulation Design: This design is meticulously crafted to meet stringent air gap and creepage distance standards, all while streamlining the device's dimensions. The result is a structure that is not only compact and rational but also visually appealing.
2. Innovative Operating Mechanism: Tailored exclusively for the vacuum circuit breaker, this mechanism is engineered to complement the vacuum interrupter's properties, ensuring outstanding reliability, an impressive lifespan, and operation that requires no maintenance.
3. Flexible Handcart Design: Featuring a screw-rod push mechanism, this design allows effortless insertion or withdrawal from the panel. Equipped with a robust mechanical interlock that performs 'Five Prevention' functions, it is adept for diverse operational settings, even under challenging conditions.
