style="text-indent:25px">電線檢查法：重量：質(zhì)量好的電線，一般都在規(guī)定的重量范圍內(nèi)。如常用的截面積為1.5的塑料絕緣單股銅芯線，每100m重量為1.8-1.9kg；2.5的塑料絕緣單股銅芯線，每100m重量為2.8-3.0kg；4.0的塑料絕緣單股銅芯線，每100m重量為4.1-4.2kg等，音頻電纜線報(bào)價(jià)。質(zhì)量差的電線重量不足，音頻電纜線報(bào)價(jià)，要么長(zhǎng)度不夠，要么電線銅芯雜質(zhì)過多。銅質(zhì)：合格的銅芯電線銅芯應(yīng)該是紫紅色、有光澤、手感軟。廠家：假冒偽劣電線往往是“三無(wú)產(chǎn)品”，但上面卻也有模棱兩可的產(chǎn)地等標(biāo)識(shí)，如中國(guó)制造，音頻電纜線報(bào)價(jià)、中國(guó)某省或某市制造等，這實(shí)際等于未標(biāo)產(chǎn)地。價(jià)格：由于假冒偽劣電線的制作成本低，因此，商販在銷售時(shí)，常以價(jià)廉物美為幌子低價(jià)銷售，使人上當(dāng)。中國(guó)電線電纜總產(chǎn)值已超過美國(guó)，成為世界上一大電線電纜生產(chǎn)國(guó)。音頻電纜線報(bào)價(jià)</p><div

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，基本上沒有熱的因素，是屬于電擊穿的類型。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。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。在研究產(chǎn)品特性時(shí)經(jīng)常被采用。音頻電纜線報(bào)價(jià)由于電纜帶電，所以安裝需要特別謹(jǐn)慎。</p><div
