HVX12

12 kV Voltage Rating: Suitable for medium-voltage AC power distribution systems with a rated voltage of 12 kV, applicable to substations, industrial power distribution, infrastructure, etc.

Vacuum Arc Extinguishing Technology: Employs a vacuum arc extinguishing chamber for interruption, featuring low arc energy, minimal contact wear, and stable arc extinguishing performance.

High Short-Circuit Breaking Capacity: Designed for fault currents in medium-voltage systems, reliably interrupting short-circuit currents; the specific rated short-circuit breaking current needs to be confirmed based on the HVX model and configuration.

Long Mechanical Life: Optimized operating mechanism and vacuum arc extinguishing technology reduce mechanical and contact wear, suitable for power distribution applications requiring frequent operation.

Low Maintenance Requirements: The vacuum arc extinguishing chamber has a sealed structure, eliminating the need for replenishing the arc-extinguishing medium, reducing daily maintenance compared to traditional oil circuit breakers.

High Operational Reliability: Utilizes a mature energy storage operating mechanism for fast and stable opening and closing actions, and can be configured with electric energy storage and remote operation functions.

Modular Design: Compact structure, configurable with auxiliary contacts, shunt trip units, undervoltage release units, interlocking devices, and other accessories depending on the switchgear configuration.

Withdrawable Design: Some HVX configurations feature a removable/withdrawable structure, facilitating circuit breaker testing, maintenance, and replacement, improving switchgear maintenance convenience.

Comprehensive Mechanical Interlocking: Works seamlessly with the switchgear trolley, grounding switch, and cabinet doors to form a comprehensive safety interlocking system, reducing the risk of misoperation.

Strong Environmental Adaptability: Suitable for medium-voltage power distribution environments in industry, power, energy, and infrastructure, meeting long-term continuous operation requirements.

Wide Application Range: Can be used for the control and protection of transformers, busbars, motors, capacitor banks, and general medium-voltage feeders.
