The maximum conductor operating temperature is a critical parameter that determines a cable's current-carrying capacity, service life, and application suitability. For VDE-certified cables, EPR (Ethylene Propylene Rubber) insulation permits a continuous conductor operating temperature of 90°C, representing a significant advancement over older rubber insulation technologies which were typically limited to 60°C–70°C.[1][2] 最高导体工作温度是决定电缆载流量、使用寿命和应用适用性的关键参数。对于VDE认证电缆，EPR（乙丙橡胶）绝缘允许90°C的连续导体工作温度，相比传统橡胶绝缘（60°C–70°C）有显著提升。
