High-Voltage Draglines: Specifications for (N)TSCGEWÖU 3×185+3×35/3 11/11kV Australian Specs
A dragline excavator represents one of the largest continuous-duty electrical machines on Earth. Modern draglines (typical bucket capacity 100–150 cubic meters) routinely excavate 100,000+ tons of overburden daily from coal and metallic mines. A single large dragline requires continuous electrical power input of 5–10 megawatts to operate the bucket hoist mechanism, drag mechanism, swing drive, and positioning systems. This extraordinary power demand requires high-voltage transmission (typically 11kV or higher) to minimize resistive losses and keep conductor sizes manageable.
拉铲挖掘机代表地球上最大的连续负荷电机之一。现代拉铲(典型斗容量100-150立方米)经常从煤炭和金属矿山每天挖掘100,000多吨覆盖层。单个大型拉铲需要连续电力输入5-10兆瓦来操作斗提升机构、拖拽机构、摇摆驱动和定位系统。这种非凡的功率需求需要高压传输(通常11kV或更高)以最小化电阻损耗并保持导体大小可管理。


![PROTOLON (M)R-(N)TSCGEWOEU 6-35 KV 3 MYP cables must obtain MA (煤安) certification before they can be legally used in Chinese coal mines. The MA mark, administered by the National Coal Mine Safety Mark Office (煤矿安全标志办公室), represents mandatory safety certification for all underground coal mining equipment and materials. MYP cables, as mobile power supply cables for coal mining machinery, fall under the strictly regulated product categories defined in the Mining Product Safety Sign Management Catalog and must comply with Chinese national standards MT 818 series and GB 12972.[1][2] 是的,MYP电缆在中国煤矿使用前必须获得MA(煤安)认证。由国家煤矿安全标志办公室管理的MA标志,代表了所有井下煤矿设备和材料的强制性安全认证。MYP电缆作为煤矿机械的移动电源电缆,属于《矿用产品安全标志管理目录》中严格管制的产品类别,必须符合中国国家标准MT 818系列和GB 12972。](https://feichuncables.com/blog/wp-content/uploads/image-653.avif)
