電纜額定電壓的選擇 Voltage designation


· 電纜的額定電壓應(yīng)適合于電纜系統(tǒng)的運行狀況，用U0/U（Um）kV表示。
 U0－電纜設(shè)計用的導(dǎo)體對地或金屬屏蔽之間的額定工頻電壓；
 U－電纜設(shè)計用的導(dǎo)體間的額定工頻電壓；
 Um－設(shè)備可承受的“上限系統(tǒng)電壓”的上限值。
   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.
· 三相系統(tǒng)用電纜的U0值推薦如下表：
  he values of U0 recommened for cable to be used in three-phase systems are listed below:
