  電纜額定電壓的選擇

  Voltage designation

  ● 電纜的額定電壓應(yīng)適合于電纜使用系統(tǒng)的運行狀況,用Uo/U(Um)kv表示。

  Uo—電纜設(shè)計用的導(dǎo)體與屏蔽或金屬套之間的額定工頻電壓;

  U—電纜設(shè)計用的導(dǎo)體之間的額定工頻電壓;

  Um—設(shè)備可承受的“高系統(tǒng)電壓”的大值。

  The rated voltage of the cable for a given application shall be suitable for the operating conditions in the system in which the cable is used , and is expressed in the form Uo/U(Um)kv .

  Where:

  Uo—The rated power-frequency voltage between conductor and screen or metallic-sheath , for which the cable designed;

  U — The rated power –frequency voltage between conductors , for which the cable designed ;

  Um—The maximum value of the “highest system voltage “ for which the equipment may be operated.
