style="text-indent:25px">電纜的擊穿試驗(yàn)是逐級(jí)升電壓直至絕緣擊穿，求得電纜的擊穿電壓值。這類(lèi)試驗(yàn)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(chǎng)強(qiáng)度是電纜設(shè)計(jì)重要參數(shù)之一。交流擊穿強(qiáng)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(shí)擊穿，基本上沒(méi)有熱的因素，是屬于電擊穿的類(lèi)型，珠海純銅電纜線批發(fā)。因此電線電纜一般不進(jìn)行這種試驗(yàn)。另一種是逐級(jí)升壓，從較低的電壓（例如0.5~2倍的工作電壓）開(kāi)始，保持足夠的工作時(shí)間使電纜在這一電壓級(jí)中充分產(chǎn)生電與熱的作用。然后再升至另一電壓級(jí)。逐級(jí)上升直至擊穿，珠海純銅電纜線批發(fā)。每一級(jí)上升的電壓按起始加壓的百分比數(shù)逐級(jí)升高。這一試驗(yàn)中反映了熱擊穿的因素。這樣的試驗(yàn)結(jié)果有較好的參考價(jià)值，珠海純銅電纜線批發(fā)。在研究產(chǎn)品特性時(shí)經(jīng)常被采用。電線電纜的質(zhì)量管理，必須貫穿整個(gè)生產(chǎn)過(guò)程。珠海純銅電纜線批發(fā)</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(gè)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(lèi)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(wú)氧高純銅;三是材料的選用會(huì)對(duì)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(shí)，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(jì)電線電纜產(chǎn)品時(shí)必須與材料的選用同時(shí)進(jìn)行，一般采取選用幾種材料，通過(guò)工藝和與性能篩選試驗(yàn)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(gè)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(mén)類(lèi)非常普遍，品種規(guī)格(牌號(hào))特別多。</p><p
