產(chǎn)品描述
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(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)體的允許長期***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)。
26/35KV電力電纜,18/30KV交聯(lián)電纜,12/20KVYJV電纜,8.7/15KVYJV22電纜線,6/10KV鋁芯交聯(lián)電纜線,3.6/6KVYJLV單芯電纜
