銅芯鎧裝高壓電纜-YJV22-3*50mm2價格
6kV~35kV 中低壓銅芯及鋁芯交聯(lián)聚乙烯絕緣電力電纜(YJV電纜,YJV22電纜,YJLV電纜,YJLV22電纜)XLPE Insulated Power Cable | |||||||||||||||||||||||||||||||
交聯(lián)聚乙烯絕緣電力電纜是采用化學方法或物理方法,使聚乙烯分子由線型分子結(jié)構轉(zhuǎn)變?yōu)槿S網(wǎng)狀結(jié)構,由熱塑性的聚乙烯變成熱固性的交聯(lián)聚乙烯,從而提高了聚乙烯的耐老化性能、機械性能和耐環(huán)境能力,并保持了優(yōu)良的電氣性能。 銅芯鎧裝高壓電纜-YJV22-3*50mm2價格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 · 電纜的額定電壓應適合于電纜系統(tǒng)的運行狀況,用U0/U(Um)kv表示。 U0-電纜設計用的導體對地或金屬屏蔽之間的額定工頻電壓; U-電纜設計用的導體間的額定工頻電壓; Um-設備可承受的“zui高系統(tǒng)電壓”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: 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: | |||||||||||||||||||||||||||||||
