1、在訂購電子線或排線時(shi)***注明導線顏(yan)色

實際(ji)工程(cheng)(cheng)中(zhong)經常發現電子(zi)線(xian)或(huo)排線(xian)內導線(xian)的(de)(de)(de)顏色(se)不符合要求。有(you)(you)的(de)(de)(de)工程(cheng)(cheng)用的(de)(de)(de)三相(xiang)照明電子(zi)線(xian)，三根相(xiang)線(xian)是同色(se)線(xian)；有(you)(you)的(de)(de)(de)工程(cheng)(cheng)用的(de)(de)(de)單相(xiang)三芯照明電纜(lan)，導線(xian)是黃、綠(lv)、紅三色(se)。這是規范所不允許(xu)的(de)(de)(de)。此外(wai)，在導線(xian)上包色(se)帶的(de)(de)(de)補救措(cuo)施(shi)也不應該采用。所以，工程(cheng)(cheng)中(zhong)訂(ding)購電子(zi)線(xian)或(huo)排線(xian)時(shi)，除型號(hao)外(wai)還應注明導線(xian)的(de)(de)(de)截面和顏色(se)

2、保護地線的顏色

規范(fan)規定應(ying)采用(yong)黃綠(lv)顏色相間(jian)的(de)絕緣導(dao)線(xian)。“應(ying)”的(de)含義是***，在正常情況下(xia)均***采用(yong)黃綠(lv)相間(jian)的(de)絕緣導(dao)線(xian)。

3、中性線顏色

規(gui)范規(gui)定中(zhong)(zhong)性(xing)線(xian)宜采(cai)用(yong)淡藍色(se)(se)(se)絕緣導線(xian)。“宜”的(de)含義是(shi)：在條件(jian)許可時(shi)首(shou)先應采(cai)用(yong)淡藍色(se)(se)(se)。有的(de)***中(zhong)(zhong)性(xing)線(xian)采(cai)用(yong)白色(se)(se)(se)，如(ru)果其(qi)建筑(zhu)物(wu)因業(ye)主要求采(cai)用(yong)白色(se)(se)(se)作同性(xing)線(xian)，那(nei)未該建筑(zhu)物(wu)內所(suo)有的(de)中(zhong)(zhong)性(xing)線(xian)都應采(cai)用(yong)白色(se)(se)(se)。如(ru)果中(zhong)(zhong)性(xing)電子線(xian)的(de)顏(yan)色(se)(se)(se)是(shi)深(shen)藍色(se)(se)(se)，那(nei)末相線(xian)顏(yan)色(se)(se)(se)不宜采(cai)用(yong)綠色(se)(se)(se)，因為在暗淡的(de)燈(deng)光下，深(shen)藍色(se)(se)(se)與綠色(se)(se)(se)差(cha)別不大，此時(shi)相線(xian)顏(yan)色(se)(se)(se)參(can)單(dan)相供電時(shi)，應采(cai)用(yong)紅色(se)(se)(se)或。

4、相線顏色

宜采(cai)用(yong)(yong)(yong)(yong)黃(huang)、綠、紅(hong)(hong)(hong)三(san)(san)(san)(san)色(se)(se)(se)。以三(san)(san)(san)(san)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)進(jin)建(jian)筑(zhu)物的(de)(de)(de)(de)住宅為例，三(san)(san)(san)(san)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)源引入(ru)三(san)(san)(san)(san)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)度表(biao)箱(xiang)(xiang)內(nei)時，相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)宜采(cai)用(yong)(yong)(yong)(yong)黃(huang)、綠、紅(hong)(hong)(hong)三(san)(san)(san)(san)色(se)(se)(se)；單(dan)(dan)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)源引入(ru)單(dan)(dan)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)度表(biao)箱(xiang)(xiang)時，相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)宜分別采(cai)用(yong)(yong)(yong)(yong)黃(huang)、綠、紅(hong)(hong)(hong)三(san)(san)(san)(san)色(se)(se)(se)。由單(dan)(dan)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)度表(biao)箱(xiang)(xiang)引入(ru)到住戶配(pei)電(dian)(dian)(dian)箱(xiang)(xiang)的(de)(de)(de)(de)三(san)(san)(san)(san)芯護套線(xian)(xian)(xian)(xian)(xian)，其相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)顏(yan)(yan)(yan)色(se)(se)(se)沒有(you)(you)必要和(he)所接的(de)(de)(de)(de)進(jin)戶線(xian)(xian)(xian)(xian)(xian)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)顏(yan)(yan)(yan)色(se)(se)(se)一致。只(zhi)有(you)(you)當用(yong)(yong)(yong)(yong)戶采(cai)用(yong)(yong)(yong)(yong)三(san)(san)(san)(san)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)度表(biao)箱(xiang)(xiang)時，從三(san)(san)(san)(san)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)度表(biao)箱(xiang)(xiang)引入(ru)到住戶配(pei)電(dian)(dian)(dian)箱(xiang)(xiang)的(de)(de)(de)(de)箱(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)顏(yan)(yan)(yan)色(se)(se)(se)應和(he)進(jin)三(san)(san)(san)(san)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)度表(biao)箱(xiang)(xiang)的(de)(de)(de)(de)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)一致。2~4室進(jin)住戶配(pei)電(dian)(dian)(dian)箱(xiang)(xiang)的(de)(de)(de)(de)箱(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)可用(yong)(yong)(yong)(yong)黃(huang)、綠、紅(hong)(hong)(hong)中的(de)(de)(de)(de)任意一種(zhong)，因(yin)為GB50258—96只(zhi)規定配(pei)線(xian)(xian)(xian)(xian)(xian)采(cai)用(yong)(yong)(yong)(yong)多相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)導線(xian)(xian)(xian)(xian)(xian)時，相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)顏(yan)(yan)(yan)色(se)(se)(se)才要求易(yi)于區分。例如(ru)，2室的(de)(de)(de)(de)用(yong)(yong)(yong)(yong)戶出現斷(duan)電(dian)(dian)(dian)時，根(gen)據2室的(de)(de)(de)(de)單(dan)(dan)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)電(dian)(dian)(dian)度表(biao)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)的(de)(de)(de)(de)進(jin)線(xian)(xian)(xian)(xian)(xian)是紅(hong)(hong)(hong)色(se)(se)(se)，只(zhi)要用(yong)(yong)(yong)(yong)驗電(dian)(dian)(dian)筆(bi)檢查進(jin)建(jian)筑(zhu)物的(de)(de)(de)(de)紅(hong)(hong)(hong)色(se)(se)(se)相(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)(xiang)線(xian)(xian)(xian)(xian)(xian)是否有(you)(you)電(dian)(dian)(dian)，即可判(pan)斷(duan)故障。

電子線是一種普遍的電子元器件電纜線，重要以弱電安裝安裝為插線性，應用于各式各樣電子元器件、電器產品及機械設備內部的電級電極連接線。很多 消費者在選購電子線的狀況下全是根據本身的規定進行購買，但是也是有很多 消費者對電子線并并并不是很把握，電子線的種類及色彩十分多，根據特性可分為耐高溫電子線、耐寒電子線、化學交聯電子線這種。電導體可分為絞線應是單條的電鍍錫或者裸銅心線，電鍍錫銅心線可抗氧化，絕大部分顧客會運用電鍍錫銅心線的電導體，在電纜護套方面，基礎的電子線電纜護套原材料PVC運用得較多，也是有低煙無鹵、密度高的高壓聚乙烯（PE）等特性高品質的電纜護套原材料。UL電子線在現階段目前市面上運用得比較多，普遍的規格型號有UL1007、UL1015、UL1569、UL1430、UL1431、UL3266、UL3271、UL3173、UL3321這種。
