Medium Voltage Flexible Trailing Cable for Mining Applications
中压柔性拖曳电缆用于采矿应用
Application 应用
These cables serve as power supply or connection cables for large material handling machines, such as excavators in opencast mines, subjected to extremely high mechanical stresses where abrasion and chaffing stresses are expected in trailing operation. 这些电缆用作大型物料搬运机械(如露天矿山挖掘机)的电源或连接电缆,在拖曳作业中承受极高的机械应力、磨损和摩擦应力。
Technical Reference: According to DIN VDE 0250-813 standards, NTSCGEWOEU cables are specifically designed for trailing applications in opencast mining with enhanced mechanical resistance and abrasion protection.
