剛進入交聯銅電纜電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)行(xing)(xing)業(ye)的很多(duo)新人，都(dou)會糾(jiu)結于一(yi)(yi)個(ge)問題(ti)，我(wo)剛如(ru)(ru)何(he)著手，去(qu)(qu)了(le)解這(zhe)個(ge)行(xing)(xing)業(ye)？我(wo)需(xu)要學習什么知識？蘇州電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)銷(xiao)售下(xia)面簡(jian)單(dan)談談這(zhe)個(ge)問題(ti)，希望能夠為新人拋磚引玉，幫助(zhu)他(ta)們(men)快速入行(xing)(xing)。第一(yi)(yi)，對電(dian)(dian)(dian)纜(lan)知識深(shen)入了(le)解，每(mei)一(yi)(yi)個(ge)產品的規(gui)格和型號，以及不同(tong)的用途等(deng)。第二(er)，了(le)解行(xing)(xing)業(ye)，電(dian)(dian)(dian)纜(lan)行(xing)(xing)業(ye)最明(ming)顯的特點(dian)(dian)就是(shi)(shi)(shi)非(fei)標(biao)線(xian)(xian)橫行(xing)(xing)，這(zhe)點(dian)(dian)很重要，同(tong)時(shi)知道(dao)國標(biao)線(xian)(xian)和非(fei)標(biao)線(xian)(xian)的區別。第三，如(ru)(ru)果(guo)你(ni)(ni)做的是(shi)(shi)(shi)國標(biao)線(xian)(xian)，那你(ni)(ni)就得知道(dao)你(ni)(ni)國標(biao)線(xian)(xian)和非(fei)標(biao)線(xian)(xian)比較起(qi)來優(you)勢是(shi)(shi)(shi)什么劣勢是(shi)(shi)(shi)什么，否則的話，比價(jia)格，你(ni)(ni)根(gen)本比不上非(fei)標(biao)的。第四，了(le)解渠(qu)道(dao)，你(ni)(ni)的客(ke)戶在(zai)哪(na)里(li)？去(qu)(qu)哪(na)里(li)才能找(zhao)到你(ni)(ni)的客(ke)戶？是(shi)(shi)(shi)跑建材市場(chang)還是(shi)(shi)(shi)工地(di)？如(ru)(ru)何(he)才能找(zhao)到競爭不是(shi)(shi)(shi)很激(ji)烈的市場(chang)？第五，還是(shi)(shi)(shi)關于渠(qu)道(dao)，如(ru)(ru)今又(you)什么新型的渠(qu)道(dao)？網(wang)(wang)(wang)絡渠(qu)道(dao)是(shi)(shi)(shi)一(yi)(yi)個(ge)，我(wo)如(ru)(ru)何(he)利用網(wang)(wang)(wang)絡渠(qu)道(dao)？網(wang)(wang)(wang)絡渠(qu)道(dao)有(you)哪(na)些？阿里(li)巴巴推(tui)廣、官網(wang)(wang)(wang)seo、百(bai)度(du)競價(jia)、淘寶等(deng)，這(zhe)些都(dou)是(shi)(shi)(shi)目前傳統行(xing)(xing)業(ye)最不能忽(hu)視的渠(qu)道(dao)，但是(shi)(shi)(shi)，如(ru)(ru)何(he)去(qu)(qu)操作卻是(shi)(shi)(shi)個(ge)問題(ti)，需(xu)要自(zi)己去(qu)(qu)摸索。還有(you)很多(duo)，最基本的一(yi)(yi)點(dian)(dian)是(shi)(shi)(shi)，既然入了(le)這(zhe)行(xing)(xing)，就勇敢、堅(jian)強的走下(xia)去(qu)(qu)！同(tong)時(shi)盡(jin)可能的放開(kai)自(zi)己的腦瓜子，讓自(zi)己的思路清晰(xi)起(qi)來，只有(you)這(zhe)樣，你(ni)(ni)才能不會感到迷(mi)茫，做起(qi)事情來游刃有(you)余。

江西性價比交聯銅電纜批發大家都(dou)知道電(dian)(dian)纜(lan)(lan)進(jin)水(shui)(shui)(shui)(shui)是個很嚴重的(de)(de)(de)問(wen)題，有(you)的(de)(de)(de)時(shi)(shi)候你(ni)自認為已經做得很好的(de)(de)(de)防水(shui)(shui)(shui)(shui)措施了，可是電(dian)(dian)纜(lan)(lan)還(huan)是進(jin)水(shui)(shui)(shui)(shui)了。那么電(dian)(dian)纜(lan)(lan)是怎么進(jin)水(shui)(shui)(shui)(shui)的(de)(de)(de)呢(ni)？下面我給大家介紹(shao)一(yi)下電(dian)(dian)纜(lan)(lan)進(jin)水(shui)(shui)(shui)(shui)的(de)(de)(de)原因和應對(dui)措施。1、保管時(shi)(shi)：新買的(de)(de)(de)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)，其兩(liang)頭(tou)均使用(yong)塑料密(mi)封套封住，但用(yong)去一(yi)段之后，余下的(de)(de)(de)就用(yong)塑料紙一(yi)裹，外面用(yong)繩(sheng)子(zi)一(yi)扎，密(mi)封性(xing)不好，日子(zi)一(yi)久(jiu)，水(shui)(shui)(shui)(shui)汽就會(hui)滲入電(dian)(dian)纜(lan)(lan)。2、電(dian)(dian)纜(lan)(lan)敷設(she)時(shi)(shi)：電(dian)(dian)纜(lan)(lan)敷設(she)時(shi)(shi)，其用(yong)塑料紙裹住的(de)(de)(de)電(dian)(dian)纜(lan)(lan)頭(tou)有(you)時(shi)(shi)會(hui)浸在水(shui)(shui)(shui)(shui)中，使水(shui)(shui)(shui)(shui)進(jin)入電(dian)(dian)纜(lan)(lan)；在牽引和穿管時(shi)(shi)，有(you)時(shi)(shi)會(hui)發生外護套破(po)裂現象(xiang)。3、敷設(she)后：未(wei)及時(shi)(shi)進(jin)行(xing)電(dian)(dian)纜(lan)(lan)頭(tou)制作(zuo)，使未(wei)經密(mi)封處理的(de)(de)(de)電(dian)(dian)纜(lan)(lan)端口長期暴露(lu)在空氣(qi)中，甚(shen)至浸在水(shui)(shui)(shui)(shui)中，使水(shui)(shui)(shui)(shui)汽大量進(jin)入電(dian)(dian)纜(lan)(lan)。

1. 看電纜電線長度：江西性價比交聯銅電纜國(guo)家(jia)標(biao)準規定(ding)(ding)，電(dian)線(xian)(xian)電(dian)纜(lan)每卷(juan)100米(mi)，計(ji)量誤(wu)差不(bu)大于0.5%，也(ye)就(jiu)是(shi)每卷(juan)線(xian)(xian)的(de)(de)長度為(wei)100±0.5米(mi)，但(dan)是(shi)有些商家(jia)標(biao)注的(de)(de)是(shi)100±20米(mi)，但(dan)實際上(shang)，卻只有80米(mi)左右。2. 看(kan)電(dian)阻(zu)值：電(dian)阻(zu)值超標(biao)的(de)(de)話，電(dian)線(xian)(xian)就(jiu)容易出現溫度過高、老化(hua)的(de)(de)危險，而且(qie)如果電(dian)線(xian)(xian)短(duan)路的(de)(de)話，還(huan)會(hui)引發(fa)火(huo)災。并且(qie)電(dian)阻(zu)值超標(biao)，還(huan)增(zeng)加傳輸電(dian)量時(shi)的(de)(de)消耗，增(zeng)加電(dian)費，所以，我們在選擇時(shi)，一定(ding)(ding)要(yao)留意這一點。3.看(kan)原(yuan)材料：純銅(tong)芯(xin)的(de)(de)材料導(dao)電(dian)性好，而且(qie)不(bu)易老化(hua)，更(geng)加耐用，也(ye)減少(shao)了(le)故(gu)障(zhang)發(fa)生。但(dan)是(shi)有些商家(jia)，會(hui)在銅(tong)材質(zhi)(zhi)中添(tian)加一些雜質(zhi)(zhi)銅(tong)、回收銅(tong)，還(huan)有的(de)(de)劣質(zhi)(zhi)產(chan)品通過降低銅(tong)芯(xin)實際截面積，來(lai)減少(shao)銅(tong)材質(zhi)(zhi)的(de)(de)用量，這樣(yang)容易導(dao)致電(dian)線(xian)(xian)電(dian)纜(lan)用電(dian)過程中發(fa)熱，損壞外(wai)邊的(de)(de)絕緣層塑(su)料，容易讓(rang)電(dian)線(xian)(xian)老化(hua)，導(dao)致出現漏電(dian)、短(duan)路的(de)(de)問(wen)題。

江西交聯銅電纜批發我(wo)國阻燃和(he)耐(nai)(nai)火電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)研(yan)究開發始于1982年(nian)。經過5年(nian)時(shi)間，即198年(nian)，許(xu)多(duo)(duo)電(dian)(dian)(dian)纜(lan)廠家已投入生產并(bing)為用(yong)(yong)戶所(suo)認同。針對當時(shi)對燃燒(shao)特(te)(te)性的(de)(de)命名和(he)型(xing)(xing)號(hao)(hao)比(bi)較混亂的(de)(de)情況，筆者提出以(yi)燃燒(shao)試(shi)驗方法相(xiang)對應的(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)燃燒(shao)特(te)(te)性，對防火電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)進(jin)行(xing)分(fen)類，用(yong)(yong)漢(han)語(yu)拼音(yin)的(de)(de)首位字(zi)母定(ding)型(xing)(xing)作為相(xiang)應普通(tong)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)型(xing)(xing)號(hao)(hao)的(de)(de)前(qian)綴。其中阻燃電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)類的(de)(de)型(xing)(xing)號(hao)(hao)ZR和(he)耐(nai)(nai)火電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)類的(de)(de)型(xing)(xing)號(hao)(hao)NH已沿用(yong)(yong)至今。隨著防火電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)在開發研(yan)究中所(suo)取得的(de)(de)許(xu)多(duo)(duo)新進(jin)展(zhan)，原有(you)型(xing)(xing)號(hao)(hao)已不敷使用(yong)(yong)。加之投產廠家越來(lai)越多(duo)(duo)，在制(zhi)訂企(qi)業標準(zhun)時(shi)，對有(you)關型(xing)(xing)號(hao)(hao)各(ge)取所(suo)需，又(you)造成新的(de)(de)混亂。最突(tu)出的(de)(de)表現是，電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)燃燒(shao)特(te)(te)性相(xiang)同，但名稱和(he)型(xing)(xing)號(hao)(hao)卻不同。業內及(ji)用(yong)(yong)戶強烈要求改變這個狀況，希望對型(xing)(xing)號(hao)(hao)予以(yi)統一。為此(ci)，本文提出防火電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)型(xing)(xing)號(hao)(hao)的(de)(de)編制(zhi)方法，供日(ri)后編制(zhi)企(qi)業標準(zhun)或行(xing)業標準(zhun)參考。
