UL電(dian)(dian)子(zi)(zi)線(xian)是(shi)通過UL認(ren)證的電(dian)(dian)子(zi)(zi)線(xian)的總稱，通常用于弱電(dian)(dian)工(gong)程，如電(dian)(dian)子(zi)(zi)和電(dian)(dian)氣設備的內部連接。下面就來(lai)了(le)解一下ul電(dian)(dian)子(zi)(zi)線(xian)施(shi)工(gong)時(shi)要注意的問題與優勢(shi)都有哪些(xie)？

一、ul電子線施工時要注意的問題：

　　1.大電(dian)(dian)流ul電(dian)(dian)子線(xian)引起的(de)渦(wo)流問題(ti)。施工過程中，有使(shi)用(yong)(yong)鋼(gang)支架的(de)，有使(shi)用(yong)(yong)鋼(gang)保護(hu)管的(de)，也有使(shi)用(yong)(yong)電(dian)(dian)纜(lan)(lan)卡(ka)和架空敷設的(de)，凡在(zai)周(zhou)圍(wei)形成鋼(gang)閉(bi)合(he)回(hui)路的(de)，都有可能形成渦(wo)流，尤其是在(zai)大電(dian)(dian)流電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)系(xi)統(tong)中，渦(wo)流較大。施工時，必須采取措施，防(fang)止周(zhou)圍(wei)形成鋼(gang)(鐵)閉(bi)合(he)回(hui)路，防(fang)止電(dian)(dian)纜(lan)(lan)造成渦(wo)流。

　　2.ul電(dian)(dian)子線(xian)轉(zhuan)彎造成的(de)機械損壞。由(you)于外徑(jing)大(da)，運(yun)輸敷設困難，對轉(zhuan)彎半徑(jing)的(de)要求也比(bi)較(jiao)嚴格。在(zai)施(shi)工(gong)中(zhong)，如果(guo)轉(zhuan)角(jiao)過大(da)，可(ke)能會(hui)對導(dao)體造成機械損傷(shang)，機械損傷(shang)會(hui)因電(dian)(dian)纜(lan)(lan)(lan)(lan)絕緣強度(du)下(xia)降(jiang)而導(dao)致故(gu)障。施(shi)工(gong)過程(cheng)中(zhong)發(fa)現(xian)電(dian)(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)(tou)故(gu)障。ul電(dian)(dian)子線(xian)頭(tou)(tou)(tou)制(zhi)作時，三個電(dian)(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)(tou)長度(du)一(yi)致，與設備(bei)連接(jie)時由(you)于地(di)形限(xian)制(zhi)，中(zhong)相(xiang)電(dian)(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)(tou)長度(du)變(bian)成拱形，電(dian)(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)(tou)根部受(shou)損放電(dian)(dian)。然(ran)后采取措施(shi)，在(zai)設備(bei)連接(jie)中(zhong)，適當縮短中(zhong)相(xiang)電(dian)(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)(tou)的(de)連接(jie)長度(du)，使(shi)三相(xiang)電(dian)(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)(tou)不受(shou)外力，實踐證明運(yun)行效(xiao)果(guo)良好。由(you)此可(ke)以看出，在(zai)電(dian)(dian)纜(lan)(lan)(lan)(lan)施(shi)工(gong)過程(cheng)中(zhong)，應盡可(ke)能減少電(dian)(dian)纜(lan)(lan)(lan)(lan)受(shou)到的(de)扭力。電(dian)(dian)纜(lan)(lan)(lan)(lan)轉(zhuan)彎和裕(yu)留電(dian)(dian)纜(lan)(lan)(lan)(lan)時，應使(shi)電(dian)(dian)纜(lan)(lan)(lan)(lan)自然(ran)彎曲(qu)，防止(zhi)內部機械損壞。

　　3.ul電(dian)(dian)子線的防潮問(wen)題(ti)。運行經驗表明，中低壓電(dian)(dian)力電(dian)(dian)纜(lan)故障多為(wei)電(dian)(dian)纜(lan)中間接頭和(he)(he)終端(duan)(duan)頭故障，中間接頭和(he)(he)終端(duan)(duan)頭故障多為(wei)密封不良、濕氣侵入導致(zhi)絕緣強度下降，中低壓電(dian)(dian)力電(dian)(dian)纜(lan)網(wang)多采用樹枝狀(zhuang)供電(dian)(dian)方式，終端(duan)(duan)頭數量多，因此電(dian)(dian)纜(lan)終端(duan)(duan)頭和(he)(he)中間接頭要(yao)注意密封。

　　　4.中低(di)壓電(dian)(dian)力(li)電(dian)(dian)纜(lan)接(jie)地(di)(di)問(wen)(wen)題(ti)(ti)。在公共中低(di)壓電(dian)(dian)力(li)電(dian)(dian)纜(lan)網(wang)上，由(you)于三相負(fu)荷不相等，如果使用帶金屬(shu)保護(hu)(hu)層(ceng)(ceng)的電(dian)(dian)纜(lan)，必須考慮金屬(shu)保護(hu)(hu)層(ceng)(ceng)的接(jie)地(di)(di)問(wen)(wen)題(ti)(ti)，保證金屬(shu)保護(hu)(hu)層(ceng)(ceng)的任何(he)非接(jie)地(di)(di)處的正常(chang)感應(ying)電(dian)(dian)壓不得超過100伏。在中低(di)壓電(dian)(dian)纜(lan)網(wang)中，所有電(dian)(dian)纜(lan)接(jie)頭(tou)都應(ying)設置(zhi)接(jie)地(di)(di)極(網(wang))，使金屬(shu)保護(hu)(hu)層(ceng)(ceng)可靠接(jie)地(di)(di)。

二、ul電子線的優勢：

　　具有更高(gao)的安裝可(ke)靠性和質量。排(pai)線(xian)降低了內部(bu)連接所需的硬件，如傳統(tong)電子封裝中(zhong)常用的焊點、中(zhong)繼線(xian)、底板線(xian)路和電纜(lan)，使排(pai)線(xian)能(neng)夠提供(gong)更高(gao)的安裝可(ke)靠性和質量。由多個系統(tong)組成的傳統(tong)內部(bu)連接硬件在安裝過程中(zhong)容易出(chu)現較高(gao)的元件錯位率。

　　具(ju)有優異的(de)電(dian)氣性能、介電(dian)性能和耐熱性。排線(xian)壽(shou)命一般為8000-10000次左右(you)，適用(yong)于(yu)移動部件與主板、板對(dui)板和小型電(dian)氣設備中的(de)數據(ju)傳輸電(dian)纜。
