  电缆额外电压的选择 Voltage designation
  ·YJLV电缆  YJLV电缆载流量  YJLV是什么电缆

电缆的额外电压应得当于电缆体系的运转状态，用U0/U（Um）kv表现。
  U0－电缆设计用的导体对地或金属屏蔽之间的额外工频电压；
  U－电缆设计用的导体间的额外工频电压；
  Um－设备可蒙受的“zui高体系电压”的zui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:35KV及以下高压交联电缆，YJV电缆，YJV22电缆，YJLV电缆，YJLV22电缆
  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.
