1. What Is a High Voltage Soft Starter?
A high voltage soft starter controls the startup of motors operating on 6kV–10kV power grids, gradually increasing voltage to avoid sudden current surges. SHUYI’s model is designed for heavy-duty industrial motors, protecting them from mechanical and electrical stress.

2. How It Manages High Voltage
SHUYI’s high voltage soft starter uses multi-phase thyristor modules to regulate voltage:
- Voltage Ramp-Up: Starts at 30% of rated voltage, rising steadily over 5–60 seconds.
- Current Limiting: Caps inrush current at 3x rated value (vs. 6–8x with direct startup).
- Isolation Protection: Built-in insulation monitoring prevents faults in high-voltage circuits.
3. Key Advantages for Industrial Use
- Extended Motor Life: Reduces stator winding stress by 50%, adding 5+ years to motor lifespan.
- Grid Stability: Prevents voltage dips that disrupt other equipment on the same high-voltage network.
- Cost Savings: Eliminates the need for oversized transformers, cutting initial setup costs by 15%.
4. Ideal Applications
Perfect for large-scale industrial motors:
- Mining Mills: Controls crushers and ball mills with 1000kW+ power ratings.
- Water Treatment: Starts high-voltage pumps in wastewater and desalination plants.
- Metallurgy: Manages rolling mill motors, ensuring smooth acceleration during metal processing.
5. Why Choose SHUYI’s Soft Starter?
- Robust Design: Withstands 120% overvoltage for 1 minute, suitable for unstable grids.
- Smart Monitoring: Integrated PLC communication (Modbus/Profibus) for remote status checks.
- Certified Safety: Complies with IEC 60947-4-2 standards, ensuring safe operation in high-voltage environments.
