style="text-indent:25px">電線電纜的完整命名通常較為復(fù)雜，所以人們有時用一個簡單的名稱（通常是一個類別的名稱）結(jié)合型號規(guī)格來代替完整的名稱，如“低壓電纜”表示0.6/1kV級的所有塑料絕緣類電力電纜，佛山網(wǎng)絡(luò)電纜線生產(chǎn)廠家。電線電纜的型譜較為完善，可以說，佛山網(wǎng)絡(luò)電纜線生產(chǎn)廠家，佛山網(wǎng)絡(luò)電纜線生產(chǎn)廠家，只要寫出電線電纜的標準型號規(guī)格，就能明確具體的產(chǎn)品，但它的完整命名是怎樣的呢？電線電纜產(chǎn)品的命名有以下原則：產(chǎn)品名稱中包括的內(nèi)容：⑴產(chǎn)品應(yīng)用場合或大小類名稱。⑵產(chǎn)品結(jié)構(gòu)材料或型式；⑶產(chǎn)品的重要特征或附加特征。基本按上述順序命名，有時為了強調(diào)重要或附加特征，將特征寫到前面或相應(yīng)的結(jié)構(gòu)描述前。電線電纜的任一部件或工藝過程的質(zhì)量問題，對這根電纜幾乎是無法挽回和彌補的。佛山網(wǎng)絡(luò)電纜線生產(chǎn)廠家</p><div

style="text-indent:25px">電纜老化原因：長期過負荷運行。超負荷運行，由于電流的熱效應(yīng)，負載電流通過電纜時必然導(dǎo)致導(dǎo)體發(fā)熱，同時電荷的集膚效應(yīng)以及鋼鎧的渦流損耗、絕緣介質(zhì)損耗也會產(chǎn)乍附加熱量，從而使電纜溫度升高。電纜接頭故障。電纜接頭是電纜線路中較薄弱的環(huán)節(jié)，由人員直接過失（施工不良）引發(fā)的電纜接頭故障時常發(fā)生。施工人員在制作電纜接頭過程中，如果有接頭壓接不緊、加熱不充分等原因，都會導(dǎo)致電纜頭絕緣降低，從而引發(fā)事故。環(huán)境和溫度。電纜所處的外界環(huán)境和熱源也會造成電纜溫度過高、絕緣擊穿，甚至起火。佛山網(wǎng)絡(luò)電纜線生產(chǎn)廠家電線電纜行業(yè)是中國僅次于汽車行業(yè)的第二大行業(yè)。</p><div

style="text-indent:25px">電線電纜生產(chǎn)工藝門類多、物料流量大：電線電纜制造涉及的工藝門類普遍，從有色金屬的熔煉和壓力加工，到塑料、橡膠、油漆等化工技術(shù)；纖維材料的繞包、編織等的紡織技術(shù)，到金屬材料的繞包及金屬帶材的縱包、焊接的金屬成形加工工藝等等。電線電纜制造所用的各種材料，不但類別、品種、規(guī)格多，而且數(shù)量大。因此，各種材料的用量、備用量、批料周期與批量必須核定。同時，對廢品的分解處理、回收，重復(fù)利用及廢料處理，作為管理的一個重要內(nèi)容，做好材料定額管理、重視節(jié)約工作。電線電纜生產(chǎn)中，從原材料及各種輔助材料的進出、存儲，各工序半成品的流轉(zhuǎn)到產(chǎn)品的存放、出廠，物料流量大，必須合理布局、動態(tài)管理。</p><p style="text-indent:25px">電纜的擊穿試驗是逐級升電壓直至絕緣擊穿，求得電纜的擊穿電壓值。這類試驗的目的是考核電纜絕緣承受電壓的能力與工電壓之間的安全裕度。交流擊穿電場強度是電纜設(shè)計重要參數(shù)之一。交流擊穿強度與升壓速度有很大的關(guān)系，連續(xù)升壓使電纜在幾分鐘內(nèi)擊穿稱為瞬時擊穿，基本上沒有熱的因素，是屬于電擊穿的類型。因此電線電纜一般不進行這種試驗。另一種是逐級升壓，從較低的電壓（例如0.5~2倍的工作電壓）開始，保持足夠的工作時間使電纜在這一電壓級中充分產(chǎn)生電與熱的作用。然后再升至另一電壓級。逐級上升直至擊穿。每一級上升的電壓按起始加壓的百分比數(shù)逐級升高。這一試驗中反映了熱擊穿的因素。這樣的試驗結(jié)果有較好的參考價值。在研究產(chǎn)品特性時經(jīng)常被采用。電纜的擊穿試驗是逐級升電壓直至絕緣擊穿，求得電纜的擊穿電壓值。</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。由于電纜帶電，所以安裝需要特別謹慎。佛山網(wǎng)絡(luò)電纜線生產(chǎn)廠家</p><p

style="text-indent:25px">電線的顏色含義：黑、白、綠、紅、藍、橙、棕和灰，電線外面的絕緣護套顏色通常都有自己的指代意義。所以，在擺弄新燈具時，除了關(guān)掉斷路器之外，還要確定你接下來要碰到的每根帶顏色的電線都有什么含義。美國的居民用電開始并沒有系統(tǒng)的顏色編碼，甚至都沒有正確使用的一套標準。1879年，當(dāng)愛迪生一次引入電燈后不久，保險行業(yè)開始發(fā)放一些安全指南。一套正式的指南出現(xiàn)于1881年，內(nèi)容包括編址容量、絕緣及安裝。但沒有對電線顏色進行分類。1882年，美國國家火災(zāi)保險商委員會(NBFU )也曾采用過早期的安全規(guī)章。1893年，全國保險電力協(xié)會開始試圖把各個州不同的電氣裝置準則和規(guī)范統(tǒng)一起來，提出了為建筑布線的電燈和電源裝置的全國性編碼標準。佛山網(wǎng)絡(luò)電纜線生產(chǎn)廠家</p></p><br /><p>文章來源地址:
