u0－電纜設(shè)計(jì)用的導(dǎo)體對(duì)地或金屬屏蔽之間的額定工頻電壓；
u－電纜設(shè)計(jì)用的導(dǎo)體間的額定工頻電壓；
um－設(shè)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.
