据荷兰鹿特丹城的西门子公司声称,该公司首次把一根10kv的光电复合拖曳缆用于斗式挖掘机。70mm~2的导体为挖掘机提供动力电源,光纤则承担控制信号和语言的传递。 6根芯径为50μm的渐变型光纤借助移动式变频器来传送控制信号和携带一个电话信道。通过串行接口的敬据传输码速为9600bit/s,带宽范围为0-15kHz。由于把高压电缆和光缆组合在一起,所以只要用一个收线盘,而原先要用两个,这就减轻了挖掘机的重
According to Siemens AG in Rotterdam, the Netherlands, the company is using a 10kv optoelectronic composite tow cable for the first time in a bucket excavator. 70mm ~ 2 conductor for the excavator to provide power supply, the optical fiber is assumed control signal and language transfer. Six graduated fibers with a 50 μm core diameter transmit control signals and carry a telephone channel by means of a mobile frequency converter. Respect of the serial interface Transmission speed of 9600bit / s, the bandwidth range of 0-15kHz. Due to the high-voltage cables and optical cables together, so long as the use of a take-up reel, which originally required two, which lightened the weight of the excavator
