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。

AS/NZS 1802:2003 specifically addresses cables for underground coal mining operations, where methane gas hazards and confined space requirements demand exceptional safety standards. The standard mandates electrical symmetry for alternating current supply cables—a critical safety feature that ensures balanced electromagnetic fields within the mining environment. AS/NZS 1802:2003 专门针对井下煤矿作业电缆，鉴于甲烷气体危害和受限空间的要求，该标准对交流供电电缆强制规定了电气对称性——这是确保采矿环境内电磁场平衡的关键安全特性。 AS/NZS 2802:2000 covers cables for surface mining, underground mining (excluding coal), and general industrial applications, with voltage ratings from 1.1/1.1 kV up to 33/33 kV. This standard incorporates Amendment No. 1 (December 2003) and provides specifications for two distinct cable classes based on insulation and sheath thickness. AS/NZS 2802:2000 涵盖露天矿、非煤井下矿及通用工业应用电缆，电压等级从 1.1/1.1 kV 至 33/33 kV。该标准包含2003年12月的第1号修订版，并根据绝缘和护套厚度提供两种不同电缆等级的规格。
