The Type 2S 11kV 3x95mm² cable has a base ampacity of 285 amperes when installed in free air at 40°C ambient temperature. However, in a typical underground mine substation where three or more feeder cables are installed side-by-side on a cable ladder, the practical usable current is reduced to approximately 228 amperes through application of temperature and grouping derating factors. This 228 A figure is the number that should govern your design calculations and equipment sizing for the substation feeder. Type 2S 11kV 3x95mm² 电缆在 40°C 环境温度的自由空气中安装时，其基础载流量为 285 安培。但在地下矿山变电站中，三根或更多馈电电缆并排安装在电缆桥架上的典型情况下，通过应用温度和编组降额系数，实际可用电流减少至约 228 安培。这个 228 A 的数字应该管理您的设计计算和变电站馈电的设备选型。

Underground mining operations demand exceptional reliability from every component, and the electrical cable powering Load-Haul-Dump (LHD) equipment is no exception. The Caterpillar R1700 (15-tonne capacity) and R2900 XE (18.5-tonne capacity) represent the latest generation of underground loaders, featuring advanced diesel-electric and battery-electric powertrains designed for maximum productivity and reduced emissions. Selecting the appropriate reeling cable—whether Type W or Type G-GC—directly impacts equipment uptime, operational safety, and total cost of ownership. 地下采矿作业对每个组件都要求极高的可靠性，为铲运机（LHD）设备供电的电缆也不例外。卡特彼勒R1700（15吨容量）和R2900 XE（18.5吨容量）代表了最新一代地下装载机，选择合适的卷筒电缆直接影响设备正常运行时间、操作安全性和总拥有成本。
