現如今市場銷售上的電線電纜商品90%都是選用PVC做鋼筋保護層，關鍵原因是PVC電線電纜料***性簡易、完善、成本低，能夠制作不一樣軟抗壓強度的商品，整理功效也非常好。可是，PVC不生態環境保護，在生產制造PVC電線電纜料的***性里，許多 的公司仍在提高有毒物質(鉛、鎘、鉻等重金屬污染)和高致癌物質，在欠發達***這類情況特別是在顯著。PVC生產制造時提高的增粘合劑，大部分屬于地理環境，傷害發肓和生孕作用，在歐洲***兒童玩具的制作用料上，其對PVC的運用便會有很多限制性的法律法規。UL電子線由(you)于PVC料生(sheng)(sheng)(sheng)產制造(zao)***性令(ling)人擔憂(you)的不(bu)生(sheng)(sheng)(sheng)態環(huan)境(jing)保護，因(yin)而許多(duo) 資產***已(yi)(yi)已(yi)(yi)不(bu)投資PVC制造(zao)廠，現階段(duan)的生(sheng)(sheng)(sheng)產量也(ye)在慢慢降低。

消費(fei)者在(zai)選購電(dian)(dian)纜(lan)(lan)時(shi)要注意(yi)電(dian)(dian)導體電(dian)(dian)纜(lan)(lan)線(xian)徑是否與合格證(zheng)上(shang)(shang)確(que)立(li)(li)的(de)(de)截面(mian)(mian)相一(yi)致，若電(dian)(dian)導體截面(mian)(mian)偏(pian)小(xiao)，很容易使電(dian)(dian)纜(lan)(lan)發(fa)熱(re)導致短路故障(zhang)常(chang)見故障(zhang)。建議家里照明設備線(xian)路用(yong)(yong)(yong)電(dian)(dian)纜(lan)(lan)采(cai)用(yong)(yong)(yong)1.5立(li)(li)方毫米(mi)及以上(shang)(shang)型號(hao)規格；家用(yong)(yong)(yong)中(zhong)央空調(diao)、微波爐等(deng)用(yong)(yong)(yong)功(gong)率挺大的(de)(de)家電(dian)(dian)產(chan)品應(ying)取用(yong)(yong)(yong)2.5立(li)(li)方毫米(mi)及以上(shang)(shang)型號(hao)規格的(de)(de)電(dian)(dian)纜(lan)(lan)。在(zai)選購電(dian)(dian)纜(lan)(lan)時(shi)要注意(yi)電(dian)(dian)纜(lan)(lan)的(de)(de)外觀應(ying)光滑平整，電(dian)(dian)纜(lan)(lan)護套(tao)和護線(xian)套(tao)層無損(sun)壞，標識熱(re)印清晰，手(shou)模(mo)電(dian)(dian)纜(lan)(lan)時(shi)無油膩感(gan)之(zhi)感(gan)。從電(dian)(dian)纜(lan)(lan)的(de)(de)橫截面(mian)(mian)看，電(dian)(dian)纜(lan)(lan)的(de)(de)所有(you)圓上(shang)(shang)電(dian)(dian)纜(lan)(lan)護套(tao)或(huo)護線(xian)套(tao)的(de)(de)厚薄應(ying)均(jun)勻，不能偏(pian)芯，電(dian)(dian)纜(lan)(lan)護套(tao)或(huo)護線(xian)套(tao)需(xu)有(you)的(de)(de)厚薄。
