When the cables use in alternating current system , rated voltage of cables should be at least equal the rated voltage of the system ; when the cables use in direct current system , rated voltage should be not greater than 1 . 5 times of the rated voltage of the cables 當電纜使用于交流系統時,電纜的額定電壓至少應等于該系統的額定電壓;當電纜使用地直流系統時,該系統的額定電壓應不大于電纜額定電壓的1 . 5倍。
