電(dian)(dian)(dian)(dian)纜(lan)接(jie)頭時的(de)注意(yi)事項(xiang)：a、安裝電(dian)(dian)(dian)(dian)纜(lan)終端(duan)頭時，必須剝除半導電(dian)(dian)(dian)(dian)屏蔽(bi)層，pvc電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)，操(cao)作時不(bu)得(de)損傷絕(jue)緣(yuan)，應(ying)(ying)避免刀(dao)痕(hen)及凹凸不(bu)平(ping)的(de)情況，必要時要用(yong)砂紙磨平(ping)；屏蔽(bi)端(duan)部(bu)應(ying)(ying)平(ping)整(zheng)，并要把石(shi)墨層（碳粒）清除干凈。b、塑料絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)纜(lan)端(duan)頭銅屏蔽(bi)和(he)(he)鋼鎧必須良好接(jie)地(di)，對(dui)短線路也應(ying)(ying)遵循這(zhe)項(xiang)原則，避免三相(xiang)(xiang)不(bu)平(ping)衡(heng)運行時鋼鎧端(duan)部(bu)產生(sheng)感應(ying)(ying)電(dian)(dian)(dian)(dian)動態，甚(shen)至“打火”及燃燒護套等(deng)事故。接(jie)地(di)引出(chu)線要采(cai)用(yong)鍍錫(xi)編織(zhi)銅和(he)(he)電(dian)(dian)(dian)(dian)纜(lan)銅帶(dai)連接(jie)時應(ying)(ying)用(yong)烙鐵錫(xi)焊，不(bu)宜用(yong)噴(pen)燈(deng)封焊，安徽電(dian)(dian)(dian)(dian)線，以免燒損絕(jue)緣(yuan)。c、三相(xiang)(xiang)銅屏蔽(bi)應(ying)(ying)分別(bie)與地(di)線相(xiang)(xiang)連，注意(yi)屏蔽(bi)接(jie)地(di)線和(he)(he)鋼鎧地(di)線應(ying)(ying)分別(bie)引出(chu)，相(xiang)(xiang)互絕(jue)緣(yuan)，焊接(jie)地(di)線的(de)位置應(ying)(ying)盡量靠下。

絞(jiao)制工藝(yi)分：導體絞(jiao)制、成纜(lan)、編織、鋼絲裝鎧和纏(chan)繞。3．包(bao)覆(fu)根(gen)據對(dui)電線電纜(lan)不同的(de)性能要(yao)求(qiu)，采用的(de)設備在導體的(de)外面(mian)包(bao)覆(fu)不同的(de)材(cai)(cai)料。包(bao)覆(fu)工藝(yi)分：A．擠包(bao)：橡(xiang)(xiang)膠、塑料、鉛(qian)、鋁(lv)等材(cai)(cai)料。B．縱包(bao)：橡(xiang)(xiang)皮(pi)、鋁(lv)帶(dai)材(cai)(cai)料。C．繞包(bao)：帶(dai)狀的(de)紙帶(dai)、云母帶(dai)、無堿玻璃纖維(wei)帶(dai)、無紡布、塑料帶(dai)等，線狀的(de)棉紗、絲等纖維(wei)材(cai)(cai)料。D．浸涂(tu)：絕緣漆、瀝青等。

同時(shi)，電(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)纜(lan)一米多少錢，字跡必須清晰(xi)，附近電(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)纜(lan)廠，不易(yi)擦掉。3。試彎(wan)(wan)曲(qu)。可取一根(gen)電(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)纜(lan)頭(tou)用手(shou)反復彎(wan)(wan)曲(qu)，凡(fan)是(shi)手(shou)感柔軟、抗1疲勞強度好、塑料或橡膠手(shou)感彈(dan)性大且電(dian)(dian)線(xian)(xian)(xian)(xian)絕(jue)緣(yuan)體(ti)上(shang)(shang)無龜(gui)裂的就是(shi)優(you)等(deng)品。電(dian)(dian)線(xian)(xian)(xian)(xian)絕(jue)緣(yuan)層看上(shang)(shang)去好像很厚實(shi)，實(shi)際上(shang)(shang)大多是(shi)用再生塑料制成的，只(zhi)要(yao)稍用力擠壓(ya)，擠壓(ya)處會成白(bai)色狀，彎(wan)(wan)曲(qu)4～6次就有斷線(xian)(xian)(xian)(xian)現象；4。撕(si)絕(jue)緣(yuan)。的絕(jue)緣(yuan)料都有一定的機(ji)械(xie)強度和柔性，輕(qing)易(yi)撕(si)不開的。
