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)管理中能否科學地節(jié)省材料密切相關。因此，在設計電線電纜產(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構件通用的。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。廣州戶外電纜線報價電纜老化原因可分為：外力受損，絕緣受潮和化學腐蝕。</p><div

style="text-indent:25px">安全要求：1.電纜線相互交叉時，高壓電纜應在低壓電纜下方。如果其中一條電纜在交叉點前后1m范圍內穿管保護或用隔板隔開時，較小允許距離為0.25m。2.電纜與熱力管道接近或交叉時，如有隔熱措施，平行和交叉的較小距離分別為0.5m和0.25m。3.電纜與鐵路或道路交叉時應穿管保護，保護管應伸出軌道或路面2m以外。4.電纜與建筑物基礎的距離，應能保證電纜埋設在建筑物散水以外；電纜引入建筑物時應穿管保護，保護管亦應超出建筑物散水以外。5.直接埋在地下的電纜與一般接地裝置的接地之間應相距0.25~0.5m；直接埋在地下的電纜埋設深度，一般不應小于0.7m，并應埋在凍土層下。</p><p style="text-indent:25px">電纜常見故障：電纜線路常見的故障有機械損傷、絕緣損傷、絕緣受潮、絕緣老化變質、過電壓、電纜過熱故障等。當線路發(fā)生上述故障時，應切斷故障電纜的電源，尋找故障點，對故障進行檢查及分析，然后進行修理和試驗，該割除的割除，待故障消除后，方可恢復供電。電纜故障較直接的原因是絕緣降低而被擊穿。斷線故障引起諧振的危害：斷線諧振在嚴重情況下，高頻與基頻諧振疊加，能使過壓幅值達到相電壓[P]的2.5倍，可能導致系統(tǒng)中性點位移，繞組及導線出現(xiàn)過壓，嚴重時可使絕緣閃絡，避雷器，電氣設備損壞.在某些情況下，負載變壓器相序可能反轉，還可能將過電壓傳遞到變壓器的低壓側，造成危害。電線是指傳輸電能的導線。分裸線、電磁線和絕緣線。</p><div

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計重要參數(shù)之一。交流擊穿強度與升壓速度有很大的關系，連續(xù)升壓使電纜在幾分鐘內擊穿稱為瞬時擊穿，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。這樣的試驗結果有較好的參考價值。在研究產(chǎn)品特性時經(jīng)常被采用。深圳柔性電纜線批發(fā)價</p><p
