RHEYFIRM® is Nexans' premium line of flexible medium-voltage reeling cables specifically engineered for the extreme mechanical and environmental stresses of port machinery (STS cranes, automated stacker-reclaimers) and mining equipment (continuous dragline cables, mobile crusher power systems). Unlike fixed installation cables that remain stationary throughout their service life, reeling cables experience constant dynamic stress—deploying and retracting hundreds to thousands of times over their operational life. This continuous reeling duty subjects the cable to millions of bending cycles, sustained tensile loads, electromagnetic stress, salt spray corrosion, intense ultraviolet radiation, and temperature extremes far exceeding what conventional industrial cables are designed to tolerate. The physical diameter of a reeling cable is not simply a matter of aesthetics or standardization—it directly affects how much cable can fit on a physical drum of fixed dimensions. Consider a stacker-reclaimer with an existing cable drum that has a fixed flange width (say, 1,200 millimeters) and a fixed core diameter (say, 400 millimeters). The amount of cable that can be wound onto this drum depends on how tightly the cable packs around the core. A cable with a 59-millimeter outer diameter will create a larger spiral as it is wound layer by layer, limiting the total cable length to perhaps 600 meters. That same physical drum, if fitted with a 55.8-millimeter diameter cable, creates a tighter spiral and accommodates perhaps 750 meters of cable—a 25 percent increase in usable length with zero change to the physical equipment. For equipment where travel distance requirements have increased due to terminal expansion or operational upgrades, this diameter optimization can mean the difference between being able to extend operations and being forced into an expensive drum replacement project costing hundreds of thousands of dollars.

RHEYFIRM® (RS) vs. RHEYFIRM® (RTS): When to Choose the “Reduced Diameter” Version for Space-Constrained Reels

In the hierarchy of German VDE standards, while high-voltage reeling cables like (N)TSCGEWÖU handle the massive power distribution, the NSSHÖU series (defined by DIN VDE 0250 Part 812) performs the grueling, daily operational tasks. It is termed the "workhorse" because it bridges the gap between standard rubber cables (like H07RN-F) and specialized mining cables. It offers superior mechanical strength, robust abrasion resistance, and chemical stability for dynamic applications in mines, drilling rigs, and heavy industry. 在德国 VDE 标准的体系中，虽然像 (N)TSCGEWÖU 这样的高压卷盘电缆负责大规模的配电，但 NSSHÖU 系列（由 DIN VDE 0250 第 812 部分定义）承担着繁重、日常的操作任务。它被称为“主力军（workhorse）”，因为它填补了普通橡胶电缆（如 H07RN-F）与专用矿用电缆之间的空白。它为矿山、钻井平台和重工业中的动态应用提供了卓越的机械强度、强大的耐磨性和化学稳定性。

Why is NSSHÖU considered the “workhorse” of VDE 0250 cables for low-voltage heavy-duty connections?
