6kV~35kV 中低壓銅芯及鋁芯交聯(lián)聚絕緣電力電纜（YJV電纜，YJV22電纜，YJLV電纜，YJLV22電纜）
XLPE Insulated Power Cable

yjv22-10kv銅芯電纜，yjv22-3*240每米重量及價(jià)格 交聯(lián)聚絕緣電力電纜是采用化學(xué)或物理,使聚分子由線型分子結(jié)構(gòu)轉(zhuǎn)變?yōu)槿S網(wǎng)狀結(jié)構(gòu),由熱塑性的聚變成熱固性的交聯(lián)聚,從而了聚的耐老化性能、機(jī)械性能和耐能力，并保持了優(yōu)良的電氣性能。 
交聯(lián)聚絕緣電力電纜導(dǎo)體的允許長(zhǎng)期高溫為90攝氏度，較低絕緣電纜、聚氯絕緣電纜和聚絕緣電纜高，且具有重量輕、結(jié)構(gòu)簡(jiǎn)單、使用方便、耐化學(xué)腐蝕和敷設(shè)不受落差等優(yōu)點(diǎn)。

yjv22-10kv銅芯電纜，yjv22-3*240每米重量及價(jià)格電纜額定電壓的選擇   Voltage designation

纜的額定電壓應(yīng)適合于電纜的運(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“高電壓”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 b of U0/U（Um）kv
Where:
U0－The rated power-frequency voltage between conductors and earth bllic 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:
