適用范圍 Applications
本產(chǎn)品適用于工頻額定電壓3.6/6kv～26/35kv輸配電線路作配送電能子用。
The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 3.6/6kv～26/35kv.
使用特性 Operating characteristics
· 工頻額定電壓U0/U為3.6/6kv～26/35kv。
Rated power-frepuency voltage U0/U: 3.6/6kv～26/35kv.
· 電纜導(dǎo)體的最高允許工作溫度：90℃。
Max.admissible operating temperature of the conductor:90℃.
· 短路時(shí)（最長(zhǎng)時(shí)間不超過(guò)5s）電纜導(dǎo)體的最高溫度不超過(guò)2500C。
Max. short-circurt temperature of conductor shall not exceed 2500C.
(5s maximum duration)
· 電纜敷設(shè)時(shí)環(huán)境溫度應(yīng)不低于00C。
The ambient temperature under installation should not below 00C.
· 電纜彎曲半徑：三芯電纜不小于電纜外徑15倍；單芯電纜不小于電纜外徑20倍。
The bending radius of a single-core cable should not less than 20 times of the cable diameter.
The bending radius of a single-core cable should not less than 15 times of the cable diameter.
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(yùn)行狀況，用U0/U（Um）kv表示。
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“最高系統(tǒng)電壓”的最大值。
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.
· 三相系統(tǒng)用電纜的U0值推薦如下表：
The values of U0 recommened for cable to be used in three-phase systems are listed below:
