The selection of appropriate cables for hand-held mining equipment such as borers, drills, and portable machinery is a critical safety consideration in underground coal mining and general mining operations. Australian and New Zealand Standard AS/NZS 1802 specifies construction and testing requirements for reeling and trailing cables specifically designed for use in underground coal mines, addressing the unique explosion hazards present due to methane gas and coal dust accumulation. Within this standard, different cable types serve distinct purposes, with Type 209 and Type 241 representing two fundamentally different design philosophies for power distribution to mobile equipment. 为手持采矿设备（如钻孔机、钻机和便携式机械）选择合适的电缆是地下煤矿和一般采矿作业中的关键安全考量。澳大利亚和新西兰标准AS/NZS 1802规定了专门设计用于地下煤矿的卷筒和拖拽电缆的结构和测试要求，解决了因甲烷气体和煤尘积聚而存在的独特爆炸危险。在此标准中，不同的电缆类型服务于不同的目的，其中209型和241型代表了向移动设备供电的两种根本不同的设计理念。

AS/NZS 1802 cables demonstrate strong suitability for deployment in both saline (coastal mining) environments and acidic groundwater conditions. This performance capability stems directly from the standard's specification of three key corrosion-resistant materials: tinned copper conductors, Ethylene Propylene Rubber (EPR) insulation, and Polychloroprene (PCP) heavy-duty sheathing. Each component contributes specific chemical resistance properties that collectively provide robust protection against the aggressive chemical environments encountered in Australian coastal and underground mining operations. AS/NZS 1802电缆在盐水（沿海采矿）环境和酸性地下水条件下均表现出良好的适用性。这种性能源于该标准规定的三种关键耐腐蚀材料：镀锡铜导体、乙丙橡胶（EPR）绝缘层和聚氯丁烯（PCP）重型护套。每种组件都具有特定的耐化学性能，共同为澳大利亚沿海和地下采矿作业中遇到的腐蚀性化学环境提供可靠保护。

AS/NZS 1802 is the Australian and New Zealand standard that specifies construction and testing requirements for reeling and trailing cables specifically designed for use in underground coal mines.1 These cables are engineered to withstand the harsh environmental conditions found in mining operations, including mechanical stress, moisture, and potential exposure to hazardous atmospheres. The standard aligns with AS/NZS 2802 for cables developed to meet the special requirements of the surface mining industry and introduces critical safety features including earth fault screens and central pilot cores.

Before examining why Australian mining cables require a 1.1/1.1kV rating, it is essential to understand how cable voltage ratings are expressed internationally. The rated voltage of an electrical cable is normally expressed using the combination Uo/U, where both values represent root mean squared (RMS) voltages. According to the Tratos Cable Academy and international standards, Uo represents the voltage between any insulated conductor and earth (or the metallic screen/sheath), whilst U represents the voltage between any two-phase conductors of a multicore cable. 在研究为什么澳大利亚矿用电缆需要1.1/1.1kV额定电压之前，了解国际上如何表示电缆电压额定值是至关重要的。电缆的额定电压通常使用Uo/U组合表示，两个值都代表均方根（RMS）电压。根据Tratos电缆学院和国际标准，Uo代表任何绝缘导体与接地（或金属屏蔽/护套）之间的电压，而U代表多芯电缆中任意两相导体之间的电压。
