美国(guo)(guo)从五十(shi)年(nian)代(dai)创造(zao)YJV交(jiao)(jiao)(jiao)联(lian)(lian)(lian)(lian)(lian)(lian)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)绝(jue)(jue)(jue)(jue)(jue)缘(yuan)(yuan)(yuan)(yuan)电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)，六十(shi)年(nian)代(dai)逐渐(jian)得到(dao)运(yun)(yun)用(yong)。近十(shi)年(nian)来，国(guo)(guo)内也越(yue)来越(yue)多(duo)地(di)广泛(fan)运(yun)(yun)用(yong)交(jiao)(jiao)(jiao)联(lian)(lian)(lian)(lian)(lian)(lian)绝(jue)(jue)(jue)(jue)(jue)缘(yuan)(yuan)(yuan)(yuan)，它替代(dai)了(le)PVC绝(jue)(jue)(jue)(jue)(jue)缘(yuan)(yuan)(yuan)(yuan)。那(nei)么，YJV电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)的(de)(de)(de)(de)(de)(de)优势终究在(zai)(zai)(zai)(zai)哪里(li)？他们(men)的(de)(de)(de)(de)(de)(de)差异又在(zai)(zai)(zai)(zai)哪呢？ 从分(fen)子(zi)(zi)结(jie)构图上(shang)(shang)，咱(zan)(zan)们(men)能(neng)(neng)够(gou)显着看(kan)(kan)(kan)到(dao)，PVC的(de)(de)(de)(de)(de)(de)分(fen)子(zi)(zi)是(shi)(shi)(shi)(shi)阵列有(you)序地(di)摆(bai)放，而(er)(er)(er)(er)XLPE是(shi)(shi)(shi)(shi)穿插打乱(luan)地(di)摆(bai)放。这样咱(zan)(zan)们(men)能(neng)(neng)够(gou)幻想一下，咱(zan)(zan)们(men)在(zai)(zai)(zai)(zai)撕(si)裂一块布(bu)的(de)(de)(de)(de)(de)(de)时分(fen)，假(jia)如像(xiang)PVC那(nei)样摆(bai)放的(de)(de)(de)(de)(de)(de)，咱(zan)(zan)们(men)很简(jian)单(dan)(dan)就(jiu)撕(si)裂了(le)；而(er)(er)(er)(er)像(xiang)XLPE那(nei)样摆(bai)放的(de)(de)(de)(de)(de)(de)，咱(zan)(zan)们(men)就(jiu)跟在(zai)(zai)(zai)(zai)撕(si)棉衣那(nei)种(zhong)网状(zhuang)的(de)(de)(de)(de)(de)(de)布(bu)相同(tong)，没办法简(jian)单(dan)(dan)撕(si)开(kai)了(le)。所(suo)以(yi)，YJV电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)没有(you)VV电(dian)(dian)(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)那(nei)么简(jian)单(dan)(dan)撕(si)裂。 所(suo)以(yi)，XLPE实际上(shang)(shang)便是(shi)(shi)(shi)(shi)通过物(wu)(wu)理(li)或许(xu)化学(xue)(xue)等办法（后面(mian)会(hui)具体解说），将原有(you)的(de)(de)(de)(de)(de)(de)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)(PE)分(fen)子(zi)(zi)结(jie)构打乱(luan)，也就(jiu)称(cheng)(cheng)之(zhi)为：交(jiao)(jiao)(jiao)联(lian)(lian)(lian)(lian)(lian)(lian)聚(ju)(ju)(ju)乙(yi)烯(xi)(xi)(xi)。
