電(dian)(dian)纜防(fang)(fang)火涂(tu)(tu)(tu)料(liao)(liao)施(shi)工注(zhu)意事項1。電(dian)(dian)纜防(fang)(fang)火涂(tu)(tu)(tu)料(liao)(liao)施(shi)工前應(ying)將電(dian)(dian)纜表面的(de)油(you)污、雜物、浮(fu)塵等(deng)清洗、打磨(mo)干(gan)凈，待(dai)表面干(gan)燥后再進行防(fang)(fang)火涂(tu)(tu)(tu)料(liao)(liao)的(de)施(shi)工。2。電(dian)(dian)纜防(fang)(fang)火涂(tu)(tu)(tu)料(liao)(liao)施(shi)工一(yi)般(ban)采用(yong)(yong)噴涂(tu)(tu)(tu)、刷涂(tu)(tu)(tu)等(deng)方(fang)法，使用(yong)(yong)時(shi)應(ying)充分攪拌均(jun)勻，涂(tu)(tu)(tu)料(liao)(liao)稍(shao)稠(chou)時(shi)，可用(yong)(yong)適量自來(lai)水進行稀釋(shi)，以(yi)方(fang)便噴涂(tu)(tu)(tu)為宜。3。施(shi)工過程中在涂(tu)(tu)(tu)層未(wei)干(gan)時(shi)之前，應(ying)防(fang)(fang)水、防(fang)(fang)污染(ran)、防(fang)(fang)移動、防(fang)(fang)1暴(bao)曬、防(fang)(fang)彎(wan)曲，如(ru)有(you)損壞需及(ji)時(shi)修補。4。對于塑料(liao)(liao)、橡膠(jiao)外皮的(de)電(dian)(dian)線電(dian)(dian)纜，一(yi)般(ban)是直(zhi)接涂(tu)(tu)(tu)刷防(fang)(fang)火涂(tu)(tu)(tu)料(liao)(liao)5次(ci)以(yi)上，涂(tu)(tu)(tu)層厚度為0。4-1。1mm，電(dian)(dian)線電(dian)(dian)纜批發，大約用(yong)(yong)量1。6kg每(mei)平方(fang)，對于包(bao)裝有(you)油(you)紙的(de)絕緣電(dian)(dian)纜，電(dian)(dian)纜廠(chang)建議應(ying)先包(bao)一(yi)層玻璃絲布(bu)，再進行防(fang)(fang)火涂(tu)(tu)(tu)料(liao)(liao)的(de)涂(tu)(tu)(tu)刷，如(ru)果在室外或(huo)者潮(chao)濕(shi)的(de)環境下施(shi)工，應(ying)加配(pei)套罩面清漆(qi)。

電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)老化的(de)原因(yin)你真的(de)知道嗎？1、長期(qi)負(fu)荷(he)運(yun)行。由(you)于(yu)(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)流的(de)熱效(xiao)應(ying)，電(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)制造廠家(jia)，負(fu)載電(dian)(dian)(dian)(dian)(dian)(dian)流通過電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)時必然(ran)導(dao)致(zhi)導(dao)體發熱，同時電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)的(de)集膚效(xiao)應(ying)會(hui)產生附加熱量，從(cong)而使電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)溫度升高(gao)造成(cheng)勞(lao)損(sun)。2、外(wai)力損(sun)傷。由(you)于(yu)(yu)(yu)操作不當會(hui)造成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)機械(xie)損(sun)傷。3、電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)接(jie)頭(tou)故(gu)障(zhang)。電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)接(jie)頭(tou)是電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)線路(lu)中薄(bo)弱的(de)環節(jie)，由(you)于(yu)(yu)(yu)施工不良引發的(de)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)接(jie)頭(tou)故(gu)障(zhang)時常發生。

電(dian)纜(lan)是通過：拉(la)(la)制(zhi)(zhi)(zhi)(zhi)、絞(jiao)(jiao)制(zhi)(zhi)(zhi)(zhi)、包覆三種(zhong)工藝(yi)來(lai)制(zhi)(zhi)(zhi)(zhi)作完成的，型號規格越復(fu)雜，重(zhong)復(fu)性越高。1．拉(la)(la)制(zhi)(zhi)(zhi)(zhi)在金(jin)(jin)(jin)屬壓(ya)力加工中。在外力作用下使金(jin)(jin)(jin)屬強(qiang)行通過模具（壓(ya)輪），電(dian)線電(dian)纜(lan)批發廠家，金(jin)(jin)(jin)屬橫(heng)截(jie)面(mian)積被壓(ya)縮，馬鞍山(shan)電(dian)線，并(bing)獲得(de)所要求的橫(heng)截(jie)面(mian)積形狀和尺寸的技術加工方法稱為金(jin)(jin)(jin)屬拉(la)(la)制(zhi)(zhi)(zhi)(zhi)。拉(la)(la)制(zhi)(zhi)(zhi)(zhi)工藝(yi)分：單(dan)絲(si)拉(la)(la)制(zhi)(zhi)(zhi)(zhi)和絞(jiao)(jiao)制(zhi)(zhi)(zhi)(zhi)拉(la)(la)制(zhi)(zhi)(zhi)(zhi)。2．絞(jiao)(jiao)制(zhi)(zhi)(zhi)(zhi)為了提高電(dian)線電(dian)纜(lan)的柔軟度(du)、整體度(du)，讓2根以上的單(dan)線，按著規定的方向交(jiao)織(zhi)在一起稱為絞(jiao)(jiao)制(zhi)(zhi)(zhi)(zhi)。
