1. Enhanced Safety & Compliance
Comprehensive Anti-Misoperation Mechanisms: Equipped with advanced mechanical and electrical interlock systems, the switchgear fully complies with the “Five-Prevention” safety standards, effectively preventing common operational errors such as unauthorized access, incorrect switching, and grounding mistakes.
Strict Regulatory Adherence: Meeting the State Grid’s “Eighteen Anti-Accident Measures,” it ensures a minimum insulation clearance of ≥300mm between phases and to ground, eliminating internal insulation boards for enhanced safety and reliability.
High-Altitude Adaptability: All insulation components feature large creepage distances, enabling seamless operation without modifications at altitudes below 2,300 meters, making it ideal for installations in mountainous or high-altitude regions.
2. Rigorous Testing & Certification
Type-Tested Performance: Successfully passing all 型式试验 (type tests) conducted by the National High-Voltage Electrical Appliance Quality Supervision and Inspection Center at 3150A/40kA, the switchgear guarantees consistent performance under extreme electrical conditions.
3. Innovative Structural Design
Modular & Robust Construction: Built with a modular framework crafted from 2.0mm aluminum-zinc coated steel plates, the switchgear undergoes a dual bending process and is assembled with high-strength rivets, ensuring exceptional structural integrity and an aesthetically pleasing appearance.
Ergonomic & Secure Operation: The handle-designed door lock offers effortless operation, while its longitudinal bolting mechanism inside provides robust shear resistance, effectively withstanding internal short-circuit arc faults.
Optimized Electrical Performance: Through electric field equalization measures, the switchgear achieves an ultra-low partial discharge level of <3pc at 1.2 times the rated voltage (Ur), eliminating flashover risks.
Transparent Monitoring: Front and rear viewing windows on the doors allow operators to easily observe the circuit breaker’s open/close status, trolley position, mechanism energy storage state, earthing switch position, and cable connections. The 1680mm-wide instrument and cable doors feature a double-door design for enhanced accessibility and strength.
