電纜額定電壓的選擇 Voltage designation
· 電纜的額定電壓應適合于電纜系統(tǒng)的運行狀況，用U0/U（Um）kv表示。
U0－電纜設計用的導體對地或金屬屏蔽之間的額定工頻電壓；
U－電纜設計用的導體間的額定工頻電壓；
Um－設備可承受的“ 系統(tǒng)電壓”的大值。
The rated voltage of the cable for a given applixation shall be suitable for the operating conditions
in the system in which the cable is used,and is expressed in the form of U0/U（Um）kv
Where:
U0－The rated power-frequency voltage between conductors and earth metallic screen ,for which the cable designed;
U － The rated power-frequency voltage between conductos, for which the cable designed;
Um－ The maximum value of the“highest system voltage”for which the equipment may beused.
