護(hu)(hu)套(tao)厚(hou)度(du)對電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)質量(liang)常見(jian)的(de)(de)(de)影響(xiang)有(you)(you)哪(na)(na)些呢？1、直(zhi)接響(xiang)到(dao)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)產品正常使用(yong)時(shi)(shi)長。電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)在(zai)正常應用(yong)時(shi)(shi)，電(dian)(dian)(dian)線(xian)品牌(pai)有(you)(you)哪(na)(na)些，經常是(shi)直(zhi)埋、浸(jin)在(zai)水(shui)里或(huo)暴露在(zai)易被腐蝕的(de)(de)(de)環境(jing)中(zhong)。長時(shi)(shi)間(jian)浸(jin)水(shui)或(huo)受外界腐蝕，使得質量(liang)不(bu)達標(biao)的(de)(de)(de)護(hu)(hu)套(tao)會被擊(ji)穿，這樣電(dian)(dian)(dian)纜(lan)(lan)護(hu)(hu)套(tao)防(fang)護(hu)(hu)作用(yong)就會失去。2、增加(jia)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)鋪設的(de)(de)(de)難度(du)越來越多的(de)(de)(de)環境(jing)要求高壓電(dian)(dian)(dian)纜(lan)(lan)產品必須(xu)做(zuo)到(dao)外徑小，在(zai)鋪設的(de)(de)(de)過(guo)程中(zhong)需要考(kao)慮(lv)留有(you)(you)空隙，這樣才(cai)能(neng)散發掉電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)通電(dian)(dian)(dian)后(hou)產生的(de)(de)(de)熱量(liang)，護(hu)(hu)套(tao)厚(hou)度(du)過(guo)厚(hou)會增加(jia)鋪設的(de)(de)(de)難度(du)，所以護(hu)(hu)套(tao)的(de)(de)(de)厚(hou)度(du)要求嚴格符合相關的(de)(de)(de)標(biao)準，不(bu)然無法起到(dao)保護(hu)(hu)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)作用(yong)。也不(bu)能(neng)一(yi)味的(de)(de)(de)追求其厚(hou)度(du)。

如(ru)何選(xuan)擇電(dian)(dian)(dian)(dian)(dian)纜(lan)附(fu)(fu)件(jian)產品(pin)(pin)？（1）電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)性(xing)能(neng)。電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)性(xing)能(neng)的(de)好壞是(shi)評判電(dian)(dian)(dian)(dian)(dian)纜(lan)附(fu)(fu)件(jian)品(pin)(pin)質(zhi)(zhi)的(de)首要原則。主要考慮電(dian)(dian)(dian)(dian)(dian)纜(lan)附(fu)(fu)件(jian)的(de)電(dian)(dian)(dian)(dian)(dian)場(chang)分布(bu)是(shi)否合理，改善電(dian)(dian)(dian)(dian)(dian)場(chang)分布(bu)的(de)措施(shi)是(shi)否恰當，材料的(de)電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)強度、介質(zhi)(zhi)損耗(hao)和產品(pin)(pin)的(de)絕緣裕度等。（2）密封(feng)性(xing)能(neng)。密封(feng)防潮性(xing)能(neng)直(zhi)接(jie)(jie)影(ying)響(xiang)電(dian)(dian)(dian)(dian)(dian)纜(lan)附(fu)(fu)件(jian)的(de)電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)性(xing)能(neng)和使(shi)用(yong)壽(shou)命。終端的(de)密封(feng)結構是(shi)否可靠、穩定。一般來說，中間接(jie)(jie)頭(tou)也(ye)應(ying)有(you)一個與之(zhi)相匹(pi)配(pei)金屬防潮外殼(ke)，特別是(shi)直(zhi)埋或使(shi)用(yong)在潮濕環(huan)境中。（3）機械性(xing)能(neng)。電(dian)(dian)(dian)(dian)(dian)纜(lan)附(fu)(fu)件(jian)應(ying)該有(you)足(zu)夠的(de)抗(kang)彎、防震的(de)能(neng)力(li)。中間接(jie)(jie)頭(tou)應(ying)能(neng)承受一定的(de)拉力(li)和防止(zhi)外力(li)損傷的(de)措施(shi)。（4）工(gong)藝(yi)(yi)性(xing)能(neng)。工(gong)藝(yi)(yi)性(xing)能(neng)是(shi)電(dian)(dian)(dian)(dian)(dian)纜(lan)附(fu)(fu)件(jian)設計和選(xuan)型(xing)的(de)一個重要的(de)條件(jian)，電(dian)(dian)(dian)(dian)(dian)線的(de)規格型(xing)號，標(biao)準設計、工(gong)藝(yi)(yi)可靠，提升(sheng)品(pin)(pin)質(zhi)(zhi)的(de)重要手(shou)段。

而(er)且也要看電纜本身(shen)是(shi)否有商標、規格、電壓等。還要看電線(xian)銅(tong)(tong)(tong)芯(xin)的(de)橫截面(mian)，合肥電線(xian)，的(de)紫銅(tong)(tong)(tong)顏色(se)光亮、色(se)澤(ze)柔和。2、稱重量(liang)(liang)。質(zhi)量(liang)(liang)好(hao)的(de)電線(xian)，一般都在規定的(de)重量(liang)(liang)范圍內。比如常用的(de)截面(mian)積為(wei)1。5平方的(de)塑(su)料絕緣單(dan)(dan)股銅(tong)(tong)(tong)芯(xin)線(xian)，每(mei)100m重量(liang)(liang)為(wei)1。8~1。9KG，2。5平方的(de)塑(su)料絕緣單(dan)(dan)股銅(tong)(tong)(tong)芯(xin)線(xian)，每(mei)100m的(de)重量(liang)(liang)為(wei)3~3。1kg。質(zhi)量(liang)(liang)差的(de)電纜重量(liang)(liang)不足(zu)，要么長度不夠，要么電線(xian)的(de)銅(tong)(tong)(tong)芯(xin)雜(za)質(zhi)太多(duo)。
