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(gòu)轉(zhuǎn)變?yōu)槿S網(wǎng)狀結(jié)構(gòu),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。
交聯(lián)聚乙烯絕緣電力電纜導體的允許長期溫為90攝氏度，較低絕緣電纜、聚氯乙烯絕緣電纜和聚乙烯絕緣電纜高，且具有重量輕、結(jié)構(gòu)簡單、使用方便、耐化學腐蝕和敷設(shè)不受落差限制等優(yōu)點。

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)的運行狀況，用U0/U（Um）kv表示。
U0－電纜設(shè)計用的導體對地或金屬之間的額定工頻電壓；
U－電纜設(shè)計用的導體間的額定工頻電壓；
Um－設(shè)備可承受的“系統(tǒng)電壓”的值。
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.
