In modern tunnel boring machine (TBM) applications, the selection of appropriate voltage ratings for cutterhead drive systems is critical for operational efficiency, safety, and equipment longevity. For Herrenknecht TBMs—the world’s leading manufacturer of mechanized tunneling equipment—the standard voltage rating for cutterhead high-voltage drives is predominantly 6kV (6/10kV class) and 10kV, with 20kV systems reserved for specialized high-power applications exceeding 5MW per motor. 在现代隧道掘进机（TBM）应用中，刀盘驱动系统的电压等级选择对运行效率、安全性和设备寿命至关重要。对于海瑞克TBM——全球领先的机械化隧道设备制造商——刀盘高压驱动的标准电压等级主要为6kV（6/10kV级）和10kV，20kV系统仅用于单电机功率超过5MW的特殊高功率应用。
