普通電線(xiàn)電纜會(huì )存在的問(wèn)題

由于電線(xiàn)電纜的絕緣層和護套層采用的是有機材料，這些材料在溫度超過(guò)一定范圍時(shí)，將會(huì )產(chǎn)生燃燒或延燃現象。而電線(xiàn)電纜在長(cháng)期帶載運行的情況下，導體本身的熱量會(huì )使絕緣層和護套層產(chǎn)生局部老化。

視頻用的同軸電纜和網(wǎng)絡(luò )用的同軸電纜一樣的嗎？

同軸電纜可分為兩種基本類(lèi)型,基帶同軸電纜和寬帶同軸電纜。目前基帶常用的電纜,其屏蔽線(xiàn)是用銅做成的網(wǎng)狀的,特征阻抗為50歐(如RG-8、RG-58等);寬帶同軸電纜常用的電纜的屏蔽層通常是用鋁沖壓成的,特征阻抗為75歐(如RG-59等)。

我國電線(xiàn)電纜行業(yè)政策及競爭優(yōu)劣分析

近年來(lái)國家大力進(jìn)行城市電網(wǎng)建設、農網(wǎng)改造及城市軌道交通的建設，頒布了若干利好政策。這些行業(yè)的發(fā)展將為上游電線(xiàn)電纜生產(chǎn)企業(yè)帶來(lái)大量的訂單。同時(shí)，由于因電線(xiàn)電纜質(zhì)量原因導致的火災居高不下，為防止重大事故的再次發(fā)生，國家在電線(xiàn)電纜行業(yè)和產(chǎn)品標準方面的管控越來(lái)越嚴格，新的技術(shù)標準不斷出臺。

橡套電纜的適應范圍

橡套電纜廣泛獨霸于各類(lèi)電器設備,例如日用電器,電動(dòng)機械,電工拆卸和用具的移動(dòng)式電源線(xiàn),同時(shí)可在室內或戶(hù)外景象形象條件下獨霸.遵守電纜所受的機械外力,在產(chǎn)物結構上分為輕型,

橡套電纜開(kāi)膛破肚讓你更了解他

該問(wèn)題主要體現在以下幾個(gè)方面：①表面不光滑;表面有熟料粒子(早期硫化橡膠粒子)或雜質(zhì);電線(xiàn)電纜表面劃傷、擦傷;表面有塌陷;表面有麻花紋。
