BS 6724:2016 制造与工程选型指南从6941B–6945B到低烟、低腐蚀性气体、CPR与项目验收
BS 6724:2016是热固性绝缘、线铠装、低烟和低腐蚀性气体外护套固定敷设电缆的产品标准。截至2026年8月，BSI将其列为Current；公开产品批准文件通常写作“BS 6724:2016 Incorporating Corrigenda Nos. 1 and 2”。
![BS 5467:2016规定的是热固性绝缘、线铠装、外护套固定敷设电缆。BSI列出的应用是工业区、建筑及类似固定安装；标准覆盖0.6/1 kV与1.9/3.3 kV，并规定90°C最高持续导体温度及250°C、最长5 s的短路导体温度边界。[1] 因此，一根电缆即使完全符合BS 5467，也不能自动推导出它适合卷筒反复收放、拖令往复、拖链小半径循环或悬垂承拉。](https://feichuncables.com/blog/wp-content/uploads/image-1865.avif "BS 5467:2016 电缆制造与工程选型从6941X–6945X固定铠装馈线，到卷筒、拖令、拖链动态移动段 4")

Short Circuit Rating: How to Calculate the Thermal Short-Circuit Limit for the Earth Screen of a Type 209 Cable
Understanding the thermal short-circuit current limits of cable earth screens represents a critical aspect of mining cable design and electrical system safety. When a fault occurs in a mining electrical system, massive currents can flow through the cable’s protective earth screen, generating intense heat that must be contained without damaging the cable’s insulation or compromising its structural integrity. For Type 209 mining cables, which serve as flexible feeders to machinery in demanding underground coal mining environments, accurately calculating these thermal limits ensures that the composite earth screen can safely carry fault currents until protective devices clear the fault.
了解电缆地线屏蔽的热短路电流限制是矿用电缆设计和电气系统安全的关键方面。当矿山电气系统发生故障时，巨大的电流可能通过电缆的保护性地线屏蔽流动，产生必须在不损坏电缆绝缘或损害其结构完整性的情况下控制的强热。对于作为苛刻地下煤矿环境中机械柔性馈线的Type 209矿用电缆，准确计算这些热限制确保复合地线屏蔽能够安全承载故障电流，直到保护装置清除故障。
