Product introduction：

The 126(145)kV HV Vacuum circuit breaker is a cutting - edge high - voltage electrical device designed to ensure the safe and efficient operation of power systems. Leveraging vacuum as the arc - extinguishing and insulating medium, it boasts exceptional performance in rapidly interrupting fault currents, preventing arc re - ignition, and maintaining stable insulation. Its robust construction and advanced operating mechanisms guarantee reliable switching capabilities, even under extreme conditions. Ideal for substations and critical transmission lines, this breaker combines high - voltage handling capacity with long - term durability, reducing maintenance needs and enhancing overall grid reliability.

Main characteristic：

• High - Voltage Rating: Designed for 126(145)kV, suitable for major transmission and distribution systems.
• Vacuum - based Arc Extinction: Ensures rapid arc quenching and prevents re - ignition for reliable operation.
• Robust Construction: Built to withstand extreme conditions, providing mechanical stability and durability.
• Efficient Fault Interruption: Quickly cuts off fault currents to protect power grid equipment.
• Low Maintenance: Long - lasting performance reduces the frequency of servicing requirements.
