我們將(jiang)電(dian)(dian)(dian)(dian)線和電(dian)(dian)(dian)(dian)纜(lan)統一(yi)稱(cheng)為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。“電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)”是指(zhi)用于電(dian)(dian)(dian)(dian)力、電(dian)(dian)(dian)(dian)氣及相關傳(chuan)輸用途的(de)材(cai)料。“電(dian)(dian)(dian)(dian)線”和“電(dian)(dian)(dian)(dian)纜(lan)”之間(jian)并沒有嚴格(ge)的(de)界限(xian)和準(zhun)確且固定的(de)概念區分(fen)，一(yi)般(ban)僅以日常經(jing)驗(yan)來進行區分(fen)。通常將(jiang)芯數少、產品直(zhi)徑小(xiao)、結構簡單的(de)產品稱(cheng)為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)線，沒有絕(jue)緣的(de)稱(cheng)為(wei)(wei)(wei)裸電(dian)(dian)(dian)(dian)線，其(qi)他的(de)稱(cheng)為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)纜(lan)；導體截面積大于6平方毫米稱(cheng)為(wei)(wei)(wei)大電(dian)(dian)(dian)(dian)纜(lan)，導體截面積小(xiao)于或等(deng)于6平方毫米稱(cheng)為(wei)(wei)(wei)小(xiao)電(dian)(dian)(dian)(dian)線又稱(cheng)為(wei)(wei)(wei)布(bu)電(dian)(dian)(dian)(dian)線。

選擇(ze)生產(chan)(chan)工(gong)藝穩(wen)定(ding)(ding)、技術(shu)和(he)管理水平高、雜(za)質(zhi)含量連續(xu)監測、且樹脂熔融指數保持不變(bian)的交聯聚乙烯絕緣料(liao)(liao)生產(chan)(chan)廠家，保證材(cai)料(liao)(liao)性(xing)能的穩(wen)定(ding)(ding)性(xing)。采用二步法生產(chan)(chan)的交聯料(liao)(liao)，儲存(cun)期較短(duan)，一般不超過6個(ge)月，亨通(tong)光伏電(dian)線(xian)，儲存(cun)時應避(bi)免高溫多濕(shi)，以防物料(liao)(liao)交聯造成擠出表面不光滑。

電纜絕緣線芯由擠塑機頭擠出后應整體平穩地進入水中，防止水珠濺到表面。循環冷卻水時，要特別注意給水槽加水，宜采用大孔徑、低流速加水，這是因為進水口口徑小，必然會提高水流速度，高速水流會將大量空氣帶入水中，而高速水流則會將大量空氣帶入水中，并可在絕緣線芯后增加細棉紗等氣泡的裝置。

電(dian)線電(dian)纜產品(pin)按其(qi)用途分(fen)成五大(da)類：

1、裸電線：指僅有(you)導體而無絕緣層(ceng)的(de)產品，如(ru)LJ，TJ，LGJ，（JL/G）等。

2、繞(rao)組(zu)線(xian)：以繞(rao)組(zu)的形式在(zai)磁場中切(qie)割磁力線(xian)感應(ying)產生(sheng)電流或通過(guo)電流1產生(sheng)磁場所用(yong)的電線(xian)。故有(you)稱電磁線(xian)，其中包括具有(you)各種特性的漆包線(xian)，繞(rao)組(zu)線(xian)。

3、電(dian)(dian)力電(dian)(dian)纜(lan)：在(zai)電(dian)(dian)力系(xi)統主干(gan)線路中(zhong)用(yong)以傳輸和分(fen)配大功能電(dian)(dian)能的電(dian)(dian)纜(lan)產品。電(dian)(dian)力電(dian)(dian)纜(lan)的基本結(jie)構(gou)由(you)線芯（導體）、絕緣層(ceng)、屏蔽層(ceng)和保護層(ceng)四(si)部(bu)分(fen)組成

4、通(tong)(tong)信(xin)(xin)(xin)電(dian)纜(lan)和通(tong)(tong)信(xin)(xin)(xin)光纜(lan)：傳(chuan)輸(shu)音頻(pin)(pin)及音頻(pin)(pin)以上(shang)各(ge)種電(dian)訊信(xin)(xin)(xin)息(xi)用的電(dian)線電(dian)纜(lan)產(chan)品，其中包括市內通(tong)(tong)信(xin)(xin)(xin)光纜(lan)，長途對(dui)稱(cheng)電(dian)纜(lan)和同柱（干線）通(tong)(tong)信(xin)(xin)(xin)電(dian)纜(lan)。     通(tong)(tong)信(xin)(xin)(xin)光纜(lan)是(shi)以光導纖維（光纖）作(zuo)為(wei)光波傳(chuan)輸(shu)介質，進行信(xin)(xin)(xin)息(xi)傳(chuan)輸(shu)，因此(ci)又(you)稱(cheng)纖維光纜(lan)。由(you)于其傳(chuan)輸(shu)衰(shuai)減小，頻(pin)(pin)帶(dai)寬，重量(liang)輕，外徑小，不受電(dian)磁場(chang)干擾(rao)等特點，通(tong)(tong)信(xin)(xin)(xin)光纜(lan)已逐漸替代了通(tong)(tong)信(xin)(xin)(xin)電(dian)纜(lan)。

5、電(dian)氣(qi)裝(zhuang)(zhuang)備用電(dian)線電(dian)纜(lan)：從電(dian)力系統的配電(dian)點把(ba)電(dian)能直(zhi)接傳輸到各種用電(dian)設備的電(dian)源連接線路用電(dian)線纜(lan)，各種工(gong)農業裝(zhuang)(zhuang)備中(zhong)的電(dian)氣(qi)安裝(zhuang)(zhuang)和控(kong)制信(xin)號用電(dian)線電(dian)纜(lan)均居于(yu)這一類產(chan)品。
