To understand why cable sheaths in underground coal mines must be electrically conductive, we need to first explore the fundamental physics of static electricity and why it poses such an extraordinary danger in mining environments. This requirement, mandated by AS/NZS 1802:2018, is not merely a technical specification but rather a critical safety measure that has evolved from decades of mining experience and, unfortunately, from lessons learned through tragic accidents. 要理解为什么地下煤矿中的电缆护套必须具有导电性，我们首先需要探讨静电的基本物理原理，以及为什么它在采矿环境中构成如此巨大的危险。AS/NZS 1802:2018要求的这一规定不仅仅是一个技术规范，而是一项从数十年的采矿经验以及不幸的事故教训中演变而来的关键安全措施。

TENAX-SAS (N)TSCGEWOEU I 6 – 35 KV

As power supply cable to large mobile equipment in mines, specifically designed for trailing cable applications with shovels and draglines. The outer sheath is extremely robust and tough against abrasion and tearing, maintaining full flexibility in operation down to -50°C. 用作矿山大型移动设备的电源电缆，专为挖掘机和拉铲的拖曳电缆应用而设计。外护套极其坚固耐磨损和撕裂，在低至-50°C的温度下保持完全的柔韧性。

MYP cables must obtain MA (煤安) certification before they can be legally used in Chinese coal mines. The MA mark, administered by the National Coal Mine Safety Mark Office (煤矿安全标志办公室), represents mandatory safety certification for all underground coal mining equipment and materials. MYP cables, as mobile power supply cables for coal mining machinery, fall under the strictly regulated product categories defined in the Mining Product Safety Sign Management Catalog and must comply with Chinese national standards MT 818 series and GB 12972.[1][2] 是的，MYP电缆在中国煤矿使用前必须获得MA（煤安）认证。由国家煤矿安全标志办公室管理的MA标志，代表了所有井下煤矿设备和材料的强制性安全认证。MYP电缆作为煤矿机械的移动电源电缆，属于《矿用产品安全标志管理目录》中严格管制的产品类别，必须符合中国国家标准MT 818系列和GB 12972。
