RHEYFIRM® (S) series reeling cables with 3+3 core distributed earth design exhibit outer diameters ranging from approximately 40.0 mm (for 3×25+3×25/34 mm² configurations at 6/10 kV) to 76.0 mm or larger (for heavy-duty 3×185+3×95/35 mm² configurations at 12/20 kV). The nominal outer diameter depends on the specific conductor cross-section, voltage rating, and insulation thickness selected. For a typical medium-voltage marine and industrial application, a RHEYFIRM® (S) cable rated 3×70+3×35/32 mm² at 6/10 kV exhibits an outer diameter between 52.0 mm and 56.0 mm with approximate total cable weight of 4,300 kg/km (2,890 lbs/1000ft), while the corresponding 12/20 kV variant reaches 62.0 to 67.0 mm outer diameter with weights near 6,800 kg/km (4,570 lbs/1000ft).

The standard (N)TSCGEWÖU 3x50+3x25/3 trailing cable is technically rated for ambient temperatures down to approximately -10°C to -15°C under normal industrial conditions according to DIN VDE 0250 Part 813, with the 5GM5 CPE (chlorinated polyethylene) rubber jacket remaining flexible and maintaining mechanical integrity within this range. However, operating this cable in Arctic mining environments at sustained -40°C temperatures requires significant engineering reevaluation and is not recommended without specialized modifications and enhanced installation protocols. While the cable does not spontaneously fail at -40°C, the rubber jacket becomes progressively more rigid and brittle, and the minimum allowable bending radius must be expanded from the standard 15D (15 times the outer diameter) to approximately 25D to 30D or greater to prevent jacket cracking during dynamic reeling operations. At -50°C, which occurs frequently in Siberia and parts of Northern Canada during winter, standard TECWATER-family cables experience material brittleness that pushes them toward structural failure risk even without bending stress. A cable suitable for -15°C temperate mining operations is fundamentally different in its application safety profile from a cable operating continuously at -40°C in an open-pit mine where the cable must flex regularly during equipment deployment and retrieval. The distinction between "technically possible" and "operationally safe" is critical to understand: equipment that operates at extreme cold requires more than just survival—it requires predictable, controlled behavior under stress. The standard (N)TSCGEWÖU can survive brief exposure to -40°C without immediate failure, but extended service in this temperature regime demands either specification of cold-hardened alternatives or acceptance of significant operational constraints.
