一、試彎曲(qu)：可取一根(gen)電(dian)線(xian)頭用手(shou)反復彎曲(qu)，凡是(shi)(shi)手(shou)感柔軟、抗疲(pi)勞強度(du)(du)好、塑料(liao)或橡膠(jiao)手(shou)感彈性大且電(dian)線(xian)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)體(ti)上(shang)(shang)無(wu)龜(gui)裂的(de)就(jiu)是(shi)(shi)優等品。偽劣電(dian)線(xian)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)層(ceng)看(kan)(kan)(kan)上(shang)(shang)去(qu)好像很厚實，實際上(shang)(shang)大多是(shi)(shi)用再生塑料(liao)制(zhi)成的(de)，只(zhi)要稍用力擠壓，擠壓處會(hui)成白色狀，彎曲(qu)4～6次就(jiu)有(you)(you)斷(duan)線(xian)現(xian)象(xiang)。二、撕絕緣(yuan)(yuan)(yuan)(yuan)(yuan)：絕緣(yuan)(yuan)(yuan)(yuan)(yuan)料(liao)都有(you)(you)一定(ding)(ding)的(de)機(ji)(ji)械(xie)強度(du)(du)和(he)柔性，輕(qing)易撕不開的(de)。而劣質電(dian)線(xian)用手(shou)能(neng)撕下或掐下來一塊(kuai)。三、看(kan)(kan)(kan)燃(ran)(ran)(ran)燒(shao)：按規定(ding)(ding)電(dian)線(xian)的(de)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)層(ceng)都具有(you)(you)一定(ding)(ding)的(de)阻燃(ran)(ran)(ran)性。剝(bo)下一段絕緣(yuan)(yuan)(yuan)(yuan)(yuan)層(ceng)，用打火機(ji)(ji)進行點燃(ran)(ran)(ran)，離開明火后能(neng)繼(ji)續自燃(ran)(ran)(ran)的(de)是(shi)(shi)劣質線(xian)。四、驗厚度(du)(du)：截取一段絕緣(yuan)(yuan)(yuan)(yuan)(yuan)層(ceng),看(kan)(kan)(kan)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)層(ceng)的(de)斷(duan)面是(shi)(shi)否有(you)(you)肉眼可見的(de)氣(qi)孔，其線(xian)芯(xin)是(shi)(shi)否位于(yu)絕緣(yuan)(yuan)(yuan)(yuan)(yuan)層(ceng)的(de)正中(zhong)(zhong)。不居(ju)中(zhong)(zhong)的(de)是(shi)(shi)因為工藝不高而造成的(de)偏芯(xin)現(xian)象(xiang)，有(you)(you)氣(qi)孔說(shuo)明使(shi)用的(de)...

電纜的材料有哪些？

我(wo)們(men)都(dou)知(zhi)道電力的(de)傳(chuan)輸需要導(dao)體，所(suo)(suo)以(yi)(yi)電纜的(de)里(li)邊就是金(jin)(jin)(jin)屬導(dao)體，比如；銅(tong)，鋁，等(deng)(deng)等(deng)(deng)，其(qi)次(ci)就是對于金(jin)(jin)(jin)屬導(dao)體的(de)保(bao)(bao)(bao)護(hu)，不同的(de)導(dao)體，保(bao)(bao)(bao)護(hu)外皮也不同，一(yi)般都(dou)是使用橡(xiang)膠(jiao)，硅橡(xiang)膠(jiao)，交聯聚乙烯(xi)，聚乙烯(xi)，聚氯(lv)乙烯(xi)等(deng)(deng)等(deng)(deng)絕緣體，這是用來保(bao)(bao)(bao)護(hu)金(jin)(jin)(jin)屬導(dao)體的(de)。 由于電纜一(yi)般都(dou)是多(duo)跟線(xian)合在一(yi)起(qi)組成電纜的(de)，所(suo)(suo)以(yi)(yi)在外層(ceng)還需要保(bao)(bao)(bao)護(hu)集合線(xian)的(de)保(bao)(bao)(bao)護(hu)層(ceng)，一(yi)般保(bao)(bao)(bao)護(hu)層(ceng)里(li)包著三(san)到五(wu)根電線(xian)。一(yi)般保(bao)(bao)(bao)護(hu)層(ceng)需要金(jin)(jin)(jin)屬加橡(xiang)膠(jiao)的(de)組合，帶(dai)有鋼絲或(huo)者(zhe)鋼帶(dai)。
