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).

In the Nexans handling cable catalog, yellow outer sheaths are predominantly used for low-voltage (0.6/1 kV) RHEYCORD® series cables, while red outer sheaths identify medium-voltage (3–30 kV) RHEYFIRM® series cables. This color differentiation serves as a critical visual safety indicator for voltage level identification in industrial environments. 在耐克森搬运电缆目录中，黄色外护套主要用于低压(0.6/1 kV) RHEYCORD®系列电缆，而红色外护套用于标识中压(3–30 kV) RHEYFIRM®系列电缆。这种颜色区分是工业环境中电压等级识别的重要视觉安全指标。
