珠江YJV電(dian)纜(lan) 聚(ju)乙烯電(dian)纜(lan)
珠(zhu)江電纜 YJV電纜：
美國(guo)從(cong)五十(shi)年(nian)代(dai)創造(zao)YJV交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)絕(jue)(jue)(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)，六十(shi)年(nian)代(dai)逐漸得到運(yun)用(yong)。近(jin)(jin)十(shi)年(nian)來(lai)，國(guo)內也越來(lai)越多(duo)地廣泛(fan)運(yun)用(yong)交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)絕(jue)(jue)(jue)緣(yuan)，它替代(dai)了(le)(le)PVC絕(jue)(jue)(jue)緣(yuan)。那么，YJV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)(de)(de)(de)優勢終究在(zai)(zai)(zai)(zai)(zai)(zai)哪(na)里？他們(men)的(de)(de)(de)(de)(de)(de)(de)差異又(you)在(zai)(zai)(zai)(zai)(zai)(zai)哪(na)呢(ni)？ 從(cong)分(fen)子(zi)(zi)結(jie)(jie)(jie)構(gou)(gou)圖上，咱(zan)們(men)能(neng)(neng)(neng)夠顯(xian)著看(kan)(kan)到，PVC的(de)(de)(de)(de)(de)(de)(de)分(fen)子(zi)(zi)是(shi)(shi)(shi)(shi)陣列有(you)序地擺(bai)放(fang)(fang)(fang)，而(er)(er)XLPE是(shi)(shi)(shi)(shi)穿插打亂(luan)地擺(bai)放(fang)(fang)(fang)。這樣(yang)咱(zan)們(men)能(neng)(neng)(neng)夠幻想一(yi)下(xia)，咱(zan)們(men)在(zai)(zai)(zai)(zai)(zai)(zai)撕裂(lie)(lie)一(yi)塊布的(de)(de)(de)(de)(de)(de)(de)時(shi)(shi)分(fen)，假(jia)如像(xiang)PVC那樣(yang)擺(bai)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)(de)(de)，咱(zan)們(men)很簡單(dan)就撕裂(lie)(lie)了(le)(le)；而(er)(er)像(xiang)XLPE那樣(yang)擺(bai)放(fang)(fang)(fang)的(de)(de)(de)(de)(de)(de)(de)，咱(zan)們(men)就跟在(zai)(zai)(zai)(zai)(zai)(zai)撕棉衣那種網(wang)狀(zhuang)的(de)(de)(de)(de)(de)(de)(de)布相同，沒辦法簡單(dan)撕開(kai)了(le)(le)。所(suo)以，YJV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)沒有(you)VV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)那么簡單(dan)撕裂(lie)(lie)。 ? 所(suo)以，XLPE實際上便(bian)是(shi)(shi)(shi)(shi)通過(guo)物理(li)(li)或許(xu)化(hua)學等(deng)辦法（后面(mian)會具體解(jie)說(shuo)），將(jiang)原有(you)的(de)(de)(de)(de)(de)(de)(de)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)(PE)分(fen)子(zi)(zi)結(jie)(jie)(jie)構(gou)(gou)打亂(luan)，也就稱(cheng)之(zhi)為(wei)(wei)：交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)。 YJV交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)絕(jue)(jue)(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)選用(yong)的(de)(de)(de)(de)(de)(de)(de)交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)，是(shi)(shi)(shi)(shi)由熱(re)(re)塑性(xing)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)經交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)改(gai)性(xing)而(er)(er)成的(de)(de)(de)(de)(de)(de)(de)熱(re)(re)固性(xing)絕(jue)(jue)(jue)緣(yuan)體。從(cong)分(fen)子(zi)(zi)結(jie)(jie)(jie)構(gou)(gou)來(lai)看(kan)(kan)，熱(re)(re)塑性(xing)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)的(de)(de)(de)(de)(de)(de)(de)分(fen)子(zi)(zi)是(shi)(shi)(shi)(shi)線性(xing)結(jie)(jie)(jie)構(gou)(gou)，耐熱(re)(re)等(deng)級低（只(zhi)要(yao)(yao)70℃）。而(er)(er)通過(guo)交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)改(gai)性(xing)構(gou)(gou)成交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)之(zhi)后，分(fen)子(zi)(zi)結(jie)(jie)(jie)構(gou)(gou)中(zhong)(zhong)的(de)(de)(de)(de)(de)(de)(de)C-C鍵由本來(lai)的(de)(de)(de)(de)(de)(de)(de)線性(xing)結(jie)(jie)(jie)構(gou)(gou)變為(wei)(wei)梯(ti)形(xing)結(jie)(jie)(jie)構(gou)(gou)，因而(er)(er)耐熱(re)(re)等(deng)級大(da)大(da)提高(gao)（可(ke)達(da)90℃），而(er)(er)且機(ji)械、物理(li)(li)、電(dian)(dian)(dian)(dian)(dian)氣功(gong)能(neng)(neng)(neng)均(jun)比(bi)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)顯(xian)著改(gai)進。 所(suo)以，YJV與VV的(de)(de)(de)(de)(de)(de)(de)差異，只(zhi)是(shi)(shi)(shi)(shi)就在(zai)(zai)(zai)(zai)(zai)(zai)于(yu)絕(jue)(jue)(jue)緣(yuan)層所(suo)用(yong)的(de)(de)(de)(de)(de)(de)(de)資料(liao)(liao)不(bu)(bu)(bu)同罷了(le)(le)。可(ke)是(shi)(shi)(shi)(shi)，便(bian)是(shi)(shi)(shi)(shi)只(zhi)是(shi)(shi)(shi)(shi)這資料(liao)(liao)的(de)(de)(de)(de)(de)(de)(de)晉(jin)級，造(zao)就了(le)(le)今日YJV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)底子(zi)(zi)將(jiang)VV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)篩選。 現(xian)(xian)(xian)在(zai)(zai)(zai)(zai)(zai)(zai)許(xu)多(duo)設計院(yuan)現(xian)(xian)(xian)已底子(zi)(zi)不(bu)(bu)(bu)選用(yong)VV類型，而(er)(er)因為(wei)(wei)技能(neng)(neng)(neng)各方面(mian)的(de)(de)(de)(de)(de)(de)(de)開(kai)展(zhan)。YJV的(de)(de)(de)(de)(de)(de)(de)本錢現(xian)(xian)(xian)已挨(ai)近(jin)(jin)VV，所(suo)以現(xian)(xian)(xian)在(zai)(zai)(zai)(zai)(zai)(zai)出產(chan)(chan)企業(ye)為(wei)(wei)便(bian)利產(chan)(chan)品線出產(chan)(chan)，有(you)客(ke)戶需求到VV的(de)(de)(de)(de)(de)(de)(de)時(shi)(shi)分(fen)底子(zi)(zi)都(dou)會引(yin)(yin)薦客(ke)戶更(geng)改(gai)成YJV類型。

在(zai)(zai)(zai)(zai)(zai)(zai)民(min)用(yong)建筑中(zhong)(zhong)引(yin)(yin)薦運(yun)用(yong)YJV，其(qi)載流(liu)量(liang)比(bi)VV的(de)(de)(de)(de)(de)(de)(de)大(da)，更(geng)為(wei)(wei)首(shou)(shou)要(yao)(yao)的(de)(de)(de)(de)(de)(de)(de)是(shi)(shi)(shi)(shi)在(zai)(zai)(zai)(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)氣火災時(shi)(shi)，因為(wei)(wei)其(qi)絕(jue)(jue)(jue)緣(yuan)資料(liao)(liao)不(bu)(bu)(bu)含氯(lv)，焚(fen)燒時(shi)(shi)不(bu)(bu)(bu)會發生有(you)毒氣體。所(suo)以也便(bian)是(shi)(shi)(shi)(shi)說(shuo)VV的(de)(de)(de)(de)(de)(de)(de)環保(bao)功(gong)能(neng)(neng)(neng)差些，故歐(ou)洲國(guo)家已強制(zhi)在(zai)(zai)(zai)(zai)(zai)(zai)民(min)用(yong)建筑中(zhong)(zhong)運(yun)用(yong)YJV。 YJV和VV的(de)(de)(de)(de)(de)(de)(de)一(yi)些首(shou)(shou)要(yao)(yao)差異匯總： YJV在(zai)(zai)(zai)(zai)(zai)(zai)絕(jue)(jue)(jue)緣(yuan)資料(liao)(liao)上做(zuo)了(le)(le)交(jiao)(jiao)(jiao)(jiao)聯(lian)(lian)(lian)(lian)處理(li)(li)提高(gao)了(le)(le)耐熱(re)(re)溫(wen)(wen)度(du),而(er)(er)VV沒有(you)。 YJV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)正常(chang)(chang)(chang)工作溫(wen)(wen)度(du)可(ke)達(da)90℃，而(er)(er)VV只(zhi)要(yao)(yao)70℃，所(suo)以同截(jie)面(mian)積(ji)YJV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)(de)(de)(de)最大(da)載流(liu)量(liang)會比(bi)VV好（如10mm²的(de)(de)(de)(de)(de)(de)(de)YJV載流(liu)量(liang)為(wei)(wei)60A，而(er)(er)平等(deng)截(jie)面(mian)積(ji)VV的(de)(de)(de)(de)(de)(de)(de)載流(liu)量(liang)卻只(zhi)要(yao)(yao)46A）。 VV類電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)導(dao)體運(yun)轉最高(gao)額(e)外(wai)溫(wen)(wen)度(du)為(wei)(wei)70℃，短路時(shi)(shi)（持續時(shi)(shi)間小于(yu)5秒）最高(gao)溫(wen)(wen)度(du)不(bu)(bu)(bu)超越攝氏160度(du)。 YJV類電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)導(dao)體運(yun)轉最高(gao)額(e)外(wai)溫(wen)(wen)度(du)為(wei)(wei)90℃，短路時(shi)(shi)（持續時(shi)(shi)間小于(yu)5秒）最高(gao)溫(wen)(wen)度(du)不(bu)(bu)(bu)超越攝氏250度(du)。 YJV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)(de)(de)(de)運(yun)用(yong)壽命比(bi)VV電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)持久(jiu)。 可(ke)是(shi)(shi)(shi)(shi)！
