Selecting a high-voltage control cabinet involves multiple technical decisions. Missing even one critical parameter can lead to compatibility issues, safety risks, or operational inefficiency. Huadong Industry Control simplifies the process by addressing six essential parameters—delivering a complete, ready-to-install cabinet that meets your exact requirements.
1. Rated Voltage & Insulation Level
We match the cabinet’s rated voltage (e.g., 6kV, 10kV, 35kV) and insulation class to your system’s nominal voltage and transient overvoltage demands, ensuring safe, stable operation.
2. Rated Current & Short-Circuit Withstand
From busbar rating to feeder capacity, we size every current-carrying component. Short-circuit withstand (kA) is calculated for your fault level, protecting equipment and personnel.
3. Switching Device Technology
We select the optimal switching technology—vacuum circuit breaker, fixed or withdrawable design—based on your duty cycle, maintenance access, and reliability requirements.
4. Enclosure Type & Protection Rating
Indoor or outdoor? Dusty, humid, or corrosive? We specify IP (e.g., IP4X, IP54) and material (steel, stainless steel) to match your environmental conditions.
5. Protection & Control Integration
Integrated relays, metering, and logic provide overcurrent, earth fault, and voltage protection. Digital communication (IEC 61850, Modbus) enables SCADA integration and remote monitoring.
6. Internal Separation & Arc-Flash Safety
Compartmentalization (form separation), mechanical interlocks, and pressure relief features contain internal arc events, enhancing operator safety and compliance with global standards.
Instead of juggling multiple vendors, you get a single point of responsibility: design, component selection, assembly, testing, documentation, and support. Huadong Industry Control delivers high-voltage cabinets that are safe, reliable, and perfectly matched to your parameters.
