1. Enhanced Safety with Metal-Clad Enclosure
Accident Containment: The fully enclosed metal-clad structure acts as a physical barrier, preventing the spread of internal faults and safeguarding adjacent equipment and personnel.
Complete Isolation: The high-voltage and low-voltage compartments are entirely separated, minimizing the risk of cross-contamination and electrical interference.
2. User-Friendly Design
Dual-Side Maintenance: Its compact, double-sided access design streamlines maintenance procedures, reducing downtime and improving operational efficiency.
Modular Circuit Breaker: The modular design of the circuit breaker ensures simplicity, reliability, and extended service life, facilitating easy replacement and upgrades.
3. Advanced Protection Mechanisms
Five-Prevention Interlock System: Equipped with a comprehensive “Five-Prevention” interlock system, it prevents misoperations such as unauthorized access, incorrect switching, and grounding errors, enabling safe operation even with closed doors.
Internal Arc Resistance: Engineered to withstand internal fault arcs, the switchgear meets up to 40kA/1s arc withstand capability, ensuring structural integrity during extreme conditions.
4. Flexible Configuration Options
Versatile Main Switch Selection: Supports various main switches, including vacuum circuit breakers, vacuum contactors, and load switch carriages, catering to diverse power distribution requirements.
Intelligent & Remote Control: Optional electric operation modules enable remote actuation of circuit breakers and earthing switches. Integrated intelligent components allow real-time monitoring of circuit breaker mechanical properties, one-click sequential control, visual operation interfaces, temperature, partial discharge, and more. It automatically collects, stores, and analyzes equipment data for comprehensive power monitoring, energy management, and health assessment, enhancing full lifecycle management capabilities.
