贛州電線電纜規格的選擇方法：確定電線電纜使用規格(導(dao)體截面)時，一(yi)般應考慮發(fa)熱(re)，電(dian)(dian)(dian)壓(ya)(ya)損(sun)失(shi)，經濟電(dian)(dian)(dian)流(liu)(liu)密度，機(ji)(ji)械(xie)強(qiang)度等選(xuan)(xuan)擇(ze)條(tiao)(tiao)(tiao)件。根據經驗(yan)(yan)，低(di)壓(ya)(ya)動力(li)線因(yin)其(qi)(qi)負(fu)荷電(dian)(dian)(dian)流(liu)(liu)較大，故(gu)一(yi)般先按(an)發(fa)熱(re)條(tiao)(tiao)(tiao)件選(xuan)(xuan)擇(ze)截面，然(ran)后驗(yan)(yan)算其(qi)(qi)電(dian)(dian)(dian)壓(ya)(ya)損(sun)失(shi)和機(ji)(ji)械(xie)強(qiang)度;低(di)壓(ya)(ya)照明線因(yin)其(qi)(qi)對(dui)(dui)電(dian)(dian)(dian)壓(ya)(ya)水平(ping)要(yao)求較高，可先按(an)允許電(dian)(dian)(dian)壓(ya)(ya)損(sun)失(shi)條(tiao)(tiao)(tiao)件選(xuan)(xuan)擇(ze)截面，再(zai)驗(yan)(yan)算發(fa)熱(re)條(tiao)(tiao)(tiao)件和機(ji)(ji)械(xie)強(qiang)度;對(dui)(dui)高壓(ya)(ya)線路(lu)，則先按(an)經濟電(dian)(dian)(dian)流(liu)(liu)密度選(xuan)(xuan)擇(ze)截面，然(ran)后驗(yan)(yan)算其(qi)(qi)發(fa)熱(re)條(tiao)(tiao)(tiao)件和允許電(dian)(dian)(dian)壓(ya)(ya)損(sun)失(shi);而高壓(ya)(ya)架空(kong)線路(lu)，還(huan)應驗(yan)(yan)算其(qi)(qi)機(ji)(ji)械(xie)強(qiang)度。

    贛州電線電纜的(de)運輸和保管：1、運輸中嚴禁從高(gao)處扔(reng)下電(dian)纜(lan)(lan)(lan)或裝(zhuang)有電(dian)纜(lan)(lan)(lan)的(de)電(dian)纜(lan)(lan)(lan)盤，特別(bie)是在較(jiao)低(di)溫(wen)度時(一般(ban)為(wei)5℃左(zuo)右及(ji)以下),扔(reng)、摔電(dian)纜(lan)(lan)(lan)將有可能導致(zhi)絕緣、護(hu)套開裂。2、盡可能避免在露天以裸露方式存放(fang)電(dian)纜(lan)(lan)(lan)，電(dian)纜(lan)(lan)(lan)盤不允許(xu)平放(fang)，應(ying)該立放(fang)。

    贛(gan)州電(dian)線(xian)(xian)電(dian)纜(lan)的安(an)裝(zhuang)與施(shi)工(gong)：電(dian)線(xian)(xian)電(dian)纜(lan)敷設(she)安(an)裝(zhuang)的設(she)計和(he)施(shi)工(gong)應按(an) GB50217-94《電(dian)力工(gong)程電(dian)纜(lan)設(she)計規(gui)范(fan)》等(deng)有(you)關規(gui)定進行，并采用(yong)必要(yao)的電(dian)纜(lan)附件(jian)(終(zhong)端和(he)接頭)。供電(dian)系(xi)統運行質量(liang)(liang)(liang)、安(an)全性和(he)可靠性不僅與電(dian)線(xian)(xian)電(dian)纜(lan)本身質量(liang)(liang)(liang)有(you)關，還與電(dian)纜(lan)附件(jian)和(he)線(xian)(xian)路的施(shi)工(gong)質量(liang)(liang)(liang)有(you)關。通過(guo)對線(xian)(xian)路故(gu)障(zhang)統計分(fen)析(xi)，由于(yu)施(shi)工(gong)、安(an)裝(zhuang)和(he)接續等(deng)因素(su)造成的故(gu)障(zhang)往往要(yao)比電(dian)線(xian)(xian)電(dian)纜(lan)本體缺(que)陷造成的故(gu)障(zhang)可能性大得多。
