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。
