RHEYFIRM® 30kV vs. Generic (N)TSCGEWÖU: Can Standard Manufacturers Match Nexans’ 20/35kV Rating?

Yes, a highly capable cable manufacturer can absolutely engineer generic (N)TSCGEWÖU flexible reeling cables to match or even exceed the 20/35kV (36kV maximum equipment voltage) rating of Nexans’ RHEYFIRM® brand premium products. However, the critical phrase here is “highly capable manufacturer”—not every cable producer has the technical depth, quality control infrastructure, and engineering expertise to successfully execute a 20/35kV design. The fundamental cable construction—Class 5 tinned copper conductors, semi-conductive rubber inner and outer layers, EPR (ethylene propylene rubber) insulation, and a heavy-duty CPE or chloroprene outer sheath—is well understood and exists within the established scope of DIN VDE 0250-813 mining cable standards. While the traditional (N)TSCGEWÖU specification typically covers voltages up to 18/30kV, the engineering principles that govern the construction are equally applicable to 20/35kV ratings. The transition from 18/30kV to 20/35kV is not a revolutionary leap requiring entirely new materials or manufacturing processes—it is an evolutionary engineering optimization that competent manufacturers have been executing for decades. What distinguishes a genuinely compliant 20/35kV generic (N)TSCGEWÖU from a merely relabeled 18/30kV cable masquerading as 20/35kV is the application of three fundamental engineering disciplines. First, the insulation thickness must be increased according to rigorous electrical stress calculations based on IEC 60502-2 high-voltage standards, accounting for the higher electrical field strength that 20/35kV imposes on the dielectric material. Second, the semi-conductive layers must be engineered with exquisite precision to control the electric field distribution and prevent partial discharge (PD) inception, which is the primary failure mechanism for high-voltage cables subjected to continuous stress. Third, the outer sheath material must be selected and formulated from premium compounds with superior mechanical durability to withstand not only the normal environmental stresses of mining operations but also any electrical stress-related damage that might be induced by the higher voltage rating. The answer, therefore, is yes—but only when manufacturers invest in the engineering rigor and quality control discipline that the 20/35kV rating genuinely demands.
