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。
