電纜低溫動態(tài)彎曲時，普通的PVC護套電纜在-20℃、PE護套電纜-40℃下未開裂，說明電纜未局部受力和損傷時，在正常敷設溫度下的動態(tài)彎曲不會導致電纜開裂。 </p> <p> 在低于正常敷設溫度施工時，若電纜局部受到?jīng)_擊力，如碰撞、在地面摔打時則很容易出現(xiàn)絕緣和護套開裂，特別是PVC絕緣和護套電纜。河南電視電線價格金水電纜集團工作作風：認真、快捷。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">金水電纜電線是由一根或幾根柔軟的導線組成，外面包以輕軟的護層；電纜是由一根或幾根絕緣包導線組成，外面再包以金屬或橡皮制的堅韌外層。電纜與電線一般都由芯線、絕緣包皮和保護外皮三個部分組成。常用電纜的特性如下：CEF——乙丙橡膠絕緣氯丁橡膠護套，船用阻燃電力電纜。CVV——聚氯乙烯絕緣，聚氯乙烯護套船用阻燃電力電纜。氧艙電線常采用BV，BX，RV，RVV系列電線，其中： BV——銅芯聚氯乙烯絕緣電線，長期允許溫度65℃，較低溫度-15℃，工作電壓交流500V，直流1000V，固定敷設于室內(nèi)、外，可明敷也可暗敷。BX——銅芯橡皮絕緣線，較高使用溫度65℃，敷于室內(nèi)。RV——聚氯乙烯絕緣單芯軟線，較高使用溫度65℃，較低使用溫度-15℃，工作電壓交流250V，直流500V，用作儀器和設備的內(nèi)部接線。RVV——銅芯聚氯乙烯絕緣和護套軟電線，允許長期工作溫度105℃，工作電壓交流500V，直流1000V，用于潮濕，機械防護要求高，經(jīng)常移動和彎曲的場合。</p><p> 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。 </p> <p> 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，當愛迪生第1次引入電燈后不久，保險行業(yè)開始發(fā)放一些安全指南。第1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。 </p> <p> 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。金水電纜是華中地區(qū)規(guī)模較大的研發(fā)基地。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

家裝離不開電線，尤其是舊房，電線雖小“任務”重大。好多火災是由于電線線路老化，配置不合理，或者使用電線質(zhì)量低劣造成的。因此，消費者在購買電線時一定要擦亮雙眼，仔細鑒別，防患于未然。 </p> <p> 市場上的電線品種多、規(guī)格多、價格亂，消費者挑選時難度非常大。單就家庭裝修中常用的2.5平方毫米和4平方毫米兩種銅芯線的價格而言，同樣規(guī)格的一盤線，因為廠家不同，價格可相差20%～30%。至于質(zhì)量優(yōu)劣，長度是否達標，消費者對其判定更是難辨其優(yōu)。 </p> <p>
