HTR Series High-Voltage thermal resistor (brief in HTR hereinafter) is suitable for large-capacity high-voltage AC squirrel-cage asynchronous motors or high-voltage synchronous motors with asynchronous starting, used to reduce the starting voltage. The motor started with this device has characteristic that starting current is little and constant, torque gradually increase, and the process of starting has no current impact and mechanical shock, little impact on the electricity grid, and no electromagnetic interference. HTR is an ideal alternative of starting reactor and autotransformer starter products. Compared to the large capacity high-voltage frequency soft starter, it is also has advantages of simple operation, maintenance-free, non-harmonic pollution and others.
HTR is widely used for soft start of high voltage motor in voltage level of 3KV, 6KV, 10kV, and power level of 250kW to 45000kW or even greater capacity.
The device uses five patent technologies which is the most advanced in same type of products in home.
