style="text-indent:25px">中國電線電纜行業(yè)五大類產(chǎn)品——裸電線、繞組線、電氣裝備電線電纜、電力電纜及通信電纜和光纜——的產(chǎn)值分別占行業(yè)總產(chǎn)值的18%、19%、22%、31%和10%。裸線產(chǎn)品主要用作架空導(dǎo)線及其他電纜產(chǎn)品的半制品，所占份額相對穩(wěn)定。繞組線產(chǎn)品則隨著國家能源、電力供應(yīng)緊張，核能、風(fēng)能等新能源項目的建設(shè)保持同步增長。電力電纜產(chǎn)品在國家智能電網(wǎng)建設(shè)推動下，仍將保持高速增長。從2010年下半年開始，國家相繼出臺了進(jìn)一步擴(kuò)大3G和光纖寬帶投資規(guī)模、推動三網(wǎng)融合試點(diǎn)、培育戰(zhàn)略性新興產(chǎn)業(yè)等相關(guān)政策，所以未來幾年，通信電纜與光纜的市場份額將明顯擴(kuò)大。另外，電氣裝備類電纜也會隨著能源產(chǎn)業(yè)、汽車工業(yè)、建筑和家電等產(chǎn)業(yè)的快速發(fā)展保持高速增長。音頻電纜線多少錢電纜按照光伏電站的系統(tǒng)可分為直流電纜及交流電纜。</p><div

style="text-indent:25px">電纜材料：從某種意義上講，電線電纜制造行業(yè)是一個材料精加工和組裝的行業(yè)。一是材料用量巨大，線纜產(chǎn)品中的材料費(fèi)用要占制造總成本的80-90%;二是所用材料的類別、品種非常多，性能要求特別高，如導(dǎo)體用銅，要求銅的純度要在99.95%以上，有的產(chǎn)品要采用無氧高純銅;三是材料的選用會對制造工藝、產(chǎn)品的性能以及使用壽命起到?jīng)Q定性的影響。同時，電線電纜制造企業(yè)的效益也與材料的選用、加工和生產(chǎn)管理中能否科學(xué)地節(jié)省材料密切相關(guān)。因此，在設(shè)計電線電纜產(chǎn)品時必須與材料的選用同時進(jìn)行，一般采取選用幾種材料，通過工藝和與性能篩選試驗后確定。線纜產(chǎn)品用材料按其使用部位與功能、可分為導(dǎo)電材料、絕緣材料、填充材料、屏蔽材料、護(hù)層材料等。但其中有些材料是幾個結(jié)構(gòu)件通用的。尤其是熱塑性材料，如聚氯乙稀、聚乙烯等只要改變部分配方成份就可用在絕緣或護(hù)套上。線纜產(chǎn)品制造中所用材料涉及的門類非常普遍，品種規(guī)格(牌號)特別多。</p><p style="text-indent:25px">一些用戶對自己的電器使用要求、環(huán)境條件認(rèn)識不足，對電線電纜型號的使用范圍、要求、性能了解不夠而常選錯型號。比如：某煉鋼廠的爐前運(yùn)渣車，它的動力就是一臺電機(jī)，爐前溫度高達(dá)800℃～900℃，在這樣的環(huán)境條件下，由于該廠對電線電纜有何種特別要求一無所知，于是選用一般通用橡套軟電纜充YC型，結(jié)果使用時間短，護(hù)套被烤焦，既影響了生產(chǎn)，又浪費(fèi)了經(jīng)濟(jì)。后經(jīng)咨詢，選用耐火阻燃電纜，減少了更換電纜之苦及經(jīng)濟(jì)損失，保證了企業(yè)的正常生產(chǎn)。一些重要部門、高層建筑、計算中心、化工、公共游樂場所和人員集中等場合，均要使用具有消防功能的阻燃或耐火電纜；煤炭部規(guī)定在煤礦深井中使用的電纜必須具有阻燃性；還有如電梯電纜、電焊機(jī)電纜、電機(jī)引接線等，都有特殊性能要求。這些具有特殊性要求的特種電線電纜在實際使用中，一些企業(yè)特別是個體企業(yè)往往對它們認(rèn)識不足，拒絕使用；一些企業(yè)無視煤炭部規(guī)定在煤礦深井中使用的電纜必須具有阻燃性的要求，而是購買一般通用橡套軟電纜；還有一些卡拉OK廳、人員集中場合安裝一些不具有消防功能的一般電線電纜，造成極大的事故隱患。電線電纜的質(zhì)量管理，必須貫穿整個生產(chǎn)過程。</p><div
