XLPE Insulated Power Cable

　　交聯(lián)聚乙烯絕緣電力電纜是采用化學(xué)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(jī)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(dǎo)體的允許長(zhǎng)期zui高溫為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(jiǎn)單、使用方便、耐化學(xué)腐蝕和敷設(shè)不受落差限制等優(yōu)點(diǎn)。
