Comparison: (N)TSCGEWÖU vs. Nexans RHEYFIRM-RS
In demanding industrial environments such as ports, steel plants, mining facilities, and automated material handling systems, reeling cables must withstand extreme mechanical stress. Tensile strength—the maximum load a cable can bear before failure—is a critical specification when selecting cables for crane systems, spreaders, and mobile machinery.
在港口、钢铁厂、矿山及自动化物流系统等苛刻工业环境中，卷筒电缆必须承受极端机械应力。抗拉强度——电缆断裂前所能承受的最大载荷——是选择起重机、吊具及移动设备用电缆时的关键技术指标。
This technical comparison examines two industry-leading reeling cable types: the (N)TSCGEWÖU (a German-standard flexible reeling cable conforming to DIN VDE specifications) and the Nexans RHEYFIRM-RS (a premium heavy-duty cable from Nexans Germany). Both are engineered for motor-driven cable reels, but differ in construction philosophy and performance characteristics.

![In underground coal mining operations, longwall shearers represent some of the most mechanically demanding equipment environments for electrical power cables. These massive machines, weighing between 75 and 120 tonnes, traverse coal faces while cutting mineral from seams at drum rotation speeds of 20 to 50 revolutions per minute, generating substantial vibration and mechanical stress on their power supply systems[1]. The selection between Type 241 and Type 275 cables for these applications involves understanding critical differences in construction, mechanical performance, and operational suitability under the AS/NZS 1802:2018 standard framework. 在地下煤矿作业中,长壁采煤机代表了电力电缆最具机械挑战性的设备环境。这些重达75至120吨的大型机器在煤层面上移动,同时以每分钟20至50转的转鼓转速从煤层中切割矿物,对其电源系统产生巨大的振动和机械应力。](https://feichuncables.com/blog/wp-content/uploads/image-667.avif "Longwall Shearer Power Cables: Why Type 241 Outperforms Type 275 in High-Vibration Applications 19")
![Longwall mining represents the most productive underground coal extraction method available to modern mining operations, with a single longwall face capable of producing over 5,000 tonnes of coal per hour in optimized installations. At the heart of this productivity lies the longwall shearer, a massive mobile machine that travels back and forth along the coal face, cutting coal with rotating drums while advancing through seam heights ranging from 1.6 to 7 meters. The power cables supplying electricity to these shearers operate in one of the most mechanically demanding cable applications in industrial engineering, subjected to continuous motion within cable chain systems (often referred to as "Bretby chains"), constant vibration from cutting operations, tight bending radii as the shearer traverses the face, and the harsh environmental conditions characteristic of underground coal mining.[1] （长壁开采代表了现代采矿作业可用的最具生产力的地下煤炭开采方法，单个长壁工作面在优化安装中每小时可生产超过5000吨煤炭）](https://feichuncables.com/blog/wp-content/uploads/image-665-1006x702.avif "Longwall Shearer: What are the advantages of using Type 241 over Type 275 for high-vibration longwall shearer power supplies? 20")
![Type 241 mining cables represent a specialized category of flexible power cables designed for demanding underground mining applications, continuous miner feeders, and pump supply systems operating at voltages from 1.1kV to 11kV. These cables are manufactured to comply with AS/NZS 1802:2003 standards and incorporate sophisticated screening systems that balance electrical performance, mechanical flexibility, and safety requirements.[1] （241型矿用电缆是专为严苛的地下采矿应用、连续采矿机馈线和泵供电系统设计的柔性电力电缆，工作电压为1.1kV至11kV）](https://feichuncables.com/blog/wp-content/uploads/image-662.avif "Composite Screen: How does the copper/nylon braid screen in Type 241 cables handle fault currents compared to a full metallic screen? 22")
