(一)控(kong)制電(dian)(dian)(dian)纜(lan)(lan)屬于電(dian)(dian)(dian)器裝備(bei)用電(dian)(dian)(dian)纜(lan)(lan)，和(he)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)是電(dian)(dian)(dian)纜(lan)(lan)五(wu)大類中(zhong)的2個。

(二)控(kong)制電纜(lan)(lan)的(de)標(biao)準是9330，電力電纜(lan)(lan)的(de)標(biao)準是GB12706。

由于以上大(da)家(jia)(jia)講到的(de)原(yuan)因,電(dian)(dian)力電(dian)(dian)纜(lan)的(de)規格一(yi)般可以較大(da)，大(da)到500平(ping)方(常規廠家(jia)(jia)能生產(chan)的(de)范圍)，再大(da)的(de)截(jie)面一(yi)般能做的(de)廠家(jia)(jia)就相對少了，而控制電(dian)(dian)纜(lan)的(de)截(jie)面一(yi)般較小(xiao)，最大(da)一(yi)般不(bu)超過10平(ping)方。

從電(dian)纜芯(xin)(xin)數上講,電(dian)力電(dian)纜根據電(dian)網要求,最多一(yi)般為(wei)5芯(xin)(xin),而(er)控制電(dian)纜傳輸控制信號用(yong)，芯(xin)(xin)數較(jiao)多，根據標(biao)準來講多的有61芯(xin)(xin)，但也可(ke)以根據用(yong)戶要求生產了。

發展前景：電線電纜(lan)行(xing)(xing)業(ye)是中(zhong)國僅次于汽(qi)車行(xing)(xing)業(ye)的第二大(da)行(xing)(xing)業(ye)，產品品種(zhong)滿足率(lv)和國內(nei)市場(chang)占有(you)率(lv)均超(chao)過90%。  在世界范(fan)圍內(nei)，中(zhong)國電線電纜(lan)總(zong)產值已超(chao)過美國，成(cheng)為世界上(shang)第一大(da)電線電纜(lan)生產國。伴隨著中(zhong)國電線電纜(lan)行(xing)(xing)業(ye)高速(su)發展，新(xin)增企業(ye)數量不斷(duan)上(shang)升(sheng)，行(xing)(xing)業(ye)整體技術水平得到大(da)幅提高。

中(zhong)國(guo)(guo)經濟持續快速的(de)增長，為線(xian)纜(lan)(lan)產(chan)品提(ti)供了巨(ju)大(da)的(de)市(shi)(shi)場(chang)空間(jian)，中(zhong)國(guo)(guo)市(shi)(shi)場(chang)強(qiang)烈的(de)誘惑力(li)，使得(de)世界都把目光聚焦于中(zhong)國(guo)(guo)市(shi)(shi)場(chang)，在改(gai)革(ge)開(kai)放短短的(de)幾十年，中(zhong)國(guo)(guo)線(xian)纜(lan)(lan)制造業(ye)(ye)所形(xing)成的(de)龐大(da)生(sheng)產(chan)能力(li)讓世界刮目相看。隨著中(zhong)國(guo)(guo)電(dian)力(li)工(gong)業(ye)(ye)、數據(ju)通信(xin)業(ye)(ye)、城市(shi)(shi)軌道(dao)交通業(ye)(ye)、汽(qi)車業(ye)(ye)以及造船等(deng)行(xing)業(ye)(ye)規模的(de)不(bu)斷擴大(da)，對電(dian)線(xian)電(dian)纜(lan)(lan)的(de)需(xu)求也(ye)將(jiang)迅速增長，未來電(dian)線(xian)電(dian)纜(lan)(lan)業(ye)(ye)還有(you)巨(ju)大(da)的(de)發展(zhan)潛力(li)。

2008年11月，我(wo)國為應對世界(jie)金融危機(ji)(ji)，政府決定投(tou)入4萬億元拉動內(nei)需，其中有大約40%以(yi)上用于城(cheng)鄉電網建設(she)與改(gai)造(zao)(zao)。全國電線電纜行(xing)業又有了良(liang)好的市(shi)場機(ji)(ji)遇，各地電線電纜企業抓住(zhu)機(ji)(ji)遇，迎接(jie)新一輪城(cheng)鄉電網建設(she)與改(gai)造(zao)(zao)。

維(wei)修保養：控制電纜價格公式如下(xia)：銅(tong)的重量X銅(tong)價=（絲(si)徑÷2）^2X3.14X絲(si)的根(gen)數X8.9X當時銅(tong)價+10%的加(jia)工費。

控制電纜的成本價格計算：平(ping)方X1.83=銅的(de)(de)重(zhong)量(liang)X當時的(de)(de)銅價(jia)+鎧(kai)裝的(de)(de)價(jia)格(ge)（重(zhong)量(liang)X0.4元/斤(jin)）=成本(ben)價(jia)格(ge)+10%的(de)(de)加工(gong)費

電纜的(de)價格(ge)=制造材(cai)料成本+固定費(fei)用(yong)+稅收+業務費(fei)+利潤

制造材料(liao)(liao)成(cheng)本(ben)(ben)=材料(liao)(liao)成(cheng)本(ben)(ben)*（1+材料(liao)(liao)消耗）（材料(liao)(liao)成(cheng)本(ben)(ben)即為(wei)理論計(ji)算出來的值(zhi)）

(四(si))控制(zhi)電(dian)(dian)纜的截(jie)面(mian)一般(ban)都不會(hui)超過10平方，電(dian)(dian)力(li)電(dian)(dian)纜主(zhu)要是輸送電(dian)(dian)力(li)的，一般(ban)都是大截(jie)面(mian)。

固定費用根(gen)據各個公司(si)的情況有所不同，一般包括生(sheng)產(chan)工(gong)(gong)資、管理工(gong)(gong)資、水電費、修(xiu)理費、折(zhe)舊費、房租(zu)費、運輸費用

控制(zhi)電(dian)(dian)(dian)纜線(xian)路常(chang)見的(de)故(gu)障(zhang)(zhang)有機械損(sun)傷、絕緣損(sun)傷、絕緣受潮、絕緣老化(hua)變質、過(guo)電(dian)(dian)(dian)壓、電(dian)(dian)(dian)纜過(guo)熱(re)故(gu)障(zhang)(zhang)等。當線(xian)路發(fa)生上述故(gu)障(zhang)(zhang)時，應(ying)切斷故(gu)障(zhang)(zhang)電(dian)(dian)(dian)纜的(de)電(dian)(dian)(dian)源，尋(xun)找故(gu)障(zhang)(zhang)點(dian)，對故(gu)障(zhang)(zhang)進行檢查(cha)及分析(xi)，然后進行修(xiu)理(li)和試驗，該割(ge)除的(de)割(ge)除，待故(gu)障(zhang)(zhang)消除后，方可恢復供電(dian)(dian)(dian)。

安裝措施：為(wei)保證(zheng)控制(zhi)電(dian)(dian)纜(lan)在發生(sheng)絕緣擊穿(chuan)、機(ji)械(xie)損(sun)傷或(huo)著火時，減(jian)少波及的范圍(wei)，國(guo)家(jia)標準GB50217-91《電(dian)(dian)力工(gong)程(cheng)電(dian)(dian)纜(lan)設計規范》規定：雙(shuang)重化保護的電(dian)(dian)流、電(dian)(dian)壓(ya)以及直流電(dian)(dian)源和跳閘控制(zhi)回路等(deng)需要增強(qiang)可靠性的兩套系統，應采用各自獨立的控制(zhi)電(dian)(dian)纜(lan)

控制電(dian)纜(lan)投入運行后，同一(yi)電(dian)纜(lan)的(de)不同線芯(xin)之間(jian)，緊鄰(lin)平行敷設的(de)電(dian)纜(lan)之間(jian)都存在電(dian)氣(qi)干擾的(de)問題，引起電(dian)氣(qi)干擾的(de)主(zhu)要原(yuan)因有：

（1）由于外施電壓在線芯間電容(rong)耦合(he)的(de)作用下產生的(de)靜電干擾；

（2）由(you)于通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流產生的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁感應干擾(rao)。總的(de)(de)來(lai)講，當鄰近存在(zai)(zai)高電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流干擾(rao)源時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣干擾(rao)更(geng)嚴重，由(you)于同一電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)線(xian)芯(xin)之間的(de)(de)距離較小，其干擾(rao)程度(du)也遠大(da)于平(ping)行敷設的(de)(de)緊鄰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。例(li)如(ru)某超高壓(ya)變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)所分(fen)相(xiang)操(cao)作斷路器的(de)(de)控制回(hui)路，三(san)相(xiang)合(he)用一根(gen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，曾發(fa)生過這樣事(shi)(shi)故，由(you)分(fen)相(xiang)操(cao)作的(de)(de)脈(mo)沖使(shi)其它相(xiang)的(de)(de)晶(jing)閘管觸發(fa)，誤(wu)導致三(san)相(xiang)聯動，以后改(gai)用分(fen)別獨立的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，就未再發(fa)生誤(wu)動事(shi)(shi)故。又如(ru)某電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)廠的(de)(de)計算機(ji)監測系統，由(you)于將模(mo)擬量低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)平(ping)的(de)(de)信(xin)號線(xian)與變(bian)送(song)器的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源線(xian)合(he)用一根(gen)四芯(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，曾引起在(zai)(zai)信(xin)號線(xian)產生70V的(de)(de)干擾(rao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，這對以毫(hao)伏計的(de)(de)低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)平(ping)信(xin)號回(hui)路，顯然會影響正常工作。

防止或減輕電(dian)氣干擾(rao)的(de)措施，主要有以下三(san)個方(fang)面(mian)。

1、控制電纜的一(yi)個備用芯接(jie)地

實(shi)踐證明，控制電纜中一個備用(yong)芯接地時，干擾電壓(ya)的(de)幅值可降低到25%~50%，且實(shi)施簡便，而對(dui)電纜的(de)造價增加甚微。

2、對電(dian)氣干擾時會發生嚴重(zhong)后(hou)果的電(dian)路，不合用一根控制電(dian)纜其中包括：

（1）弱(ruo)電(dian)信(xin)號(hao)控制回(hui)路(lu)與強電(dian)信(xin)號(hao)控制回(hui)路(lu)；

（2）低電(dian)平信號與高(gao)電(dian)平信號的(de)回路；

（3）交(jiao)流斷路(lu)器分相(xiang)操作的(de)各(ge)相(xiang)弱電(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制(zhi)回(hui)路(lu)，都(dou)不應使用同一(yi)(yi)根控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)纜(lan)。但對(dui)弱電(dian)(dian)(dian)(dian)(dian)回(hui)路(lu)的(de)每一(yi)(yi)對(dui)往(wang)返導線如分屬于不是同一(yi)(yi)根的(de)控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)纜(lan)，在(zai)(zai)敷設(she)時有(you)可(ke)(ke)能形(xing)成環狀布置，在(zai)(zai)相(xiang)近電(dian)(dian)(dian)(dian)(dian)源的(de)電(dian)(dian)(dian)(dian)(dian)磁線交(jiao)鏈(lian)下會(hui)感生電(dian)(dian)(dian)(dian)(dian)勢，其數(shu)值可(ke)(ke)能對(dui)弱電(dian)(dian)(dian)(dian)(dian)回(hui)路(lu)低電(dian)(dian)(dian)(dian)(dian)平(ping)的(de)參數(shu)干擾影響(xiang)較大(da)，因(yin)此對(dui)往(wang)返導線仍(reng)應合用一(yi)(yi)根控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)纜(lan)為宜。

3、金屬屏(ping)蔽與屏(ping)蔽層接地

金屬屏蔽(bi)是減(jian)弱(ruo)和防(fang)止電(dian)氣(qi)干(gan)擾的(de)(de)重要措施(shi)，包括對線芯(xin)的(de)(de)總(zong)(zong)屏蔽(bi)、分屏蔽(bi)和雙層式(shi)(shi)總(zong)(zong)屏蔽(bi)等。控制電(dian)纜金屬屏蔽(bi)型式(shi)(shi)的(de)(de)選(xuan)擇(ze)，應按可能(neng)產生的(de)(de)電(dian)氣(qi)干(gan)擾影響的(de)(de)強(qiang)弱(ruo)，計入綜合抑制干(gan)擾的(de)(de)措施(shi)，以滿足降低干(gan)擾和過電(dian)壓的(de)(de)要求(qiu)。對防(fang)干(gan)擾效果的(de)(de)要求(qiu)越高，則相應的(de)(de)投資也越大，當(dang)采用(yong)鋼(gang)帶鎧(kai)裝、鋼(gang)絲編(bian)織總(zong)(zong)屏蔽(bi)時，電(dian)纜的(de)(de)價格(ge)約(yue)增(zeng)加(jia)10%~20%。

強電(dian)(dian)(dian)(dian)回(hui)路(lu)中(zhong)(zhong)的(de)(de)控制干(gan)(gan)(gan)擾，由(you)于(yu)其(qi)本身的(de)(de)信(xin)號較(jiao)強，因(yin)此除了(le)位于(yu)超(chao)高(gao)壓配電(dian)(dian)(dian)(dian)裝置(zhi)或與(yu)高(gao)壓電(dian)(dian)(dian)(dian)纜緊鄰平行(xing)較(jiao)長外，均可(ke)選用不帶(dai)(dai)金(jin)屬屏(ping)(ping)蔽的(de)(de)控制電(dian)(dian)(dian)(dian)纜。弱電(dian)(dian)(dian)(dian)信(xin)號控制回(hui)路(lu)使用的(de)(de)控制電(dian)(dian)(dian)(dian)纜，當位于(yu)存在(zai)干(gan)(gan)(gan)擾影響的(de)(de)環境，又不具備有效的(de)(de)抗干(gan)(gan)(gan)擾措施時，宜選用帶(dai)(dai)金(jin)屬屏(ping)(ping)蔽的(de)(de)控制電(dian)(dian)(dian)(dian)纜，以防(fang)止(zhi)電(dian)(dian)(dian)(dian)氣干(gan)(gan)(gan)擾會對低(di)電(dian)(dian)(dian)(dian)平信(xin)號回(hui)路(lu)產生(sheng)誤(wu)動作(zuo)或使絕緣擊(ji)穿(chuan)等影響。弱電(dian)(dian)(dian)(dian)回(hui)路(lu)的(de)(de)控制電(dian)(dian)(dian)(dian)纜如果能與(yu)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜拉開足夠的(de)(de)距離(li)，或敷設在(zai)鋼管中(zhong)(zhong)時，可(ke)能會使外部(bu)的(de)(de)電(dian)(dian)(dian)(dian)氣干(gan)(gan)(gan)擾降低(di)到允許(xu)的(de)(de)限度。

對計算機監測系統信號(hao)回路(lu)的控制電(dian)纜，其(qi)屏蔽型式選擇的原(yuan)則是：

（1）開關量信(xin)號，可用總屏(ping)蔽(bi)；

（2）高電平模擬信號，宜用(yong)對線芯的(de)總屏(ping)蔽，必要時(shi)也可用(yong)對線芯的(de)分屏(ping)蔽；

（3）低電平模擬信(xin)號或(huo)脈沖量信(xin)號，宜用對(dui)線芯的分(fen)屏(ping)蔽(bi)，必要時(shi)也可用含對(dui)線芯分(fen)屏(ping)蔽(bi)的復(fu)合總屏(ping)蔽(bi)。

關(guan)于屏蔽層(ceng)的接地方式(shi)，應(ying)注意做到以下幾點(dian)：

（1）計(ji)算(suan)機臨控系統(tong)的(de)(de)模擬信(xin)號(hao)回路的(de)(de)控制電(dian)纜(lan)屏蔽層，宜用集中(zhong)式一(yi)點(dian)接(jie)地(di)。其原因基于保(bao)證計(ji)算(suan)機監控系統(tong)正常(chang)工(gong)作的(de)(de)要(yao)求，因為即(ji)使僅1V左右的(de)(de)干(gan)擾電(dian)壓，也可能引起(qi)邏輯判斷的(de)(de)謬誤，集中(zhong)一(yi)點(dian)接(jie)地(di)可避免出現接(jie)地(di)環流；

（2）除計算機監控系統的(de)控制(zhi)電(dian)(dian)纜屏蔽層(ceng)只允許集中一點接地(di)(di)的(de)情況外，其它的(de)控制(zhi)電(dian)(dian)纜屏蔽層(ceng)，當電(dian)(dian)磁感應干(gan)擾較大時，宜采用兩點接地(di)(di)，而靜電(dian)(dian)感應的(de)干(gan)擾較大時，則(ze)采用一點接地(di)(di)；

（3）雙重(zhong)屏(ping)蔽(bi)或復合總屏(ping)蔽(bi)的(de)內屏(ping)蔽(bi)層宜用一點(dian)接(jie)地，而外屏(ping)蔽(bi)層可以兩點(dian)接(jie)地；

（4）選擇兩點(dian)接地時(shi)還應考慮在暫態(tai)電流的作用下，屏(ping)蔽(bi)層不會被燒(shao)毀(hui)。

控制(zhi)電纜(lan)安(an)裝布線(xian)的注意事項(xiang)：

1.屋檐(yan)下。電纜只在不直接(jie)暴(bao)露在陽(yang)光照(zhao)射或超高溫下，標(biao)準局域網電纜就可以應(ying)用，建(jian)議使(shi)用管道。 紫(zi)外線(UV)--不要將無紫(zi)外線防護的電纜應(ying)用于(yu)陽(yang)光的直射環(huan)境內。

2.外墻上。避免陽光直(zhi)接照射墻面及人為損壞。熱度(du)--電纜在金(jin)屬(shu)管道或線槽內的溫(wen)度(du)很高，許多聚合(he)材料在這種溫(wen)度(du)下會降低使用壽(shou)命。

3.管(guan)道(dao)里(塑料或金屬的(de))。如(ru)在(zai)管(guan)道(dao)里，注(zhu)意塑料管(guan)道(dao)的(de)損(sun)壞(huai)及(ji)金屬管(guan)道(dao)的(de)導熱。機械損(sun)壞(huai)(修復(fu)費用)--光纜(lan)的(de)修復(fu)是十分(fen)昂貴的(de)，在(zai)每一(yi)個(ge)間(jian)斷點至少需要兩(liang)次端接(jie)。

4.懸(xuan)空(kong)應用/架空(kong)電纜。考慮電纜的(de)下垂(chui)和(he)壓力。電纜是否(fou)被陽光直接(jie)照射。

5.直(zhi)接(jie)在地下電(dian)(dian)(dian)纜(lan)溝(gou)中鋪(pu)設(she)，這種環(huan)境是控制范圍(wei)最小的。電(dian)(dian)(dian)纜(lan)溝(gou)的安裝要定期進(jin)行(xing)干燥或潮(chao)濕程度(du)的檢(jian)查。接(jie)地--如(ru)果控制電(dian)(dian)(dian)纜(lan)的屏(ping)蔽層需要接(jie)地，則必須遵守相應的標準(zhun)。

6.地下管(guan)道(dao)(dao)。為(wei)便于今后的(de)升級，電(dian)(dian)纜更(geng)換以及與表面壓力(li)和周(zhou)圍環境隔離，輔(fu)(fu)設管(guan)道(dao)(dao)相隔離，輔(fu)(fu)設管(guan)道(dao)(dao)是(shi)一個(ge)較好的(de)方法(fa)。但不要寄希望于管(guan)道(dao)(dao)會永遠(yuan)保持干燥，這將影(ying)響對電(dian)(dian)纜種(zhong)類(lei)的(de)選擇。水(shui)(shui)--在局域網雙絞線電(dian)(dian)纜的(de)水(shui)(shui)分(fen)會增加電(dian)(dian)纜的(de)電(dian)(dian)容，從(cong)而降低(di)了阻抗并引起近端(duan)串擾問題。

技術參數：額定電(dian)壓(ya)：U0/U為450/750V。

導體線芯長期工作溫度為70℃、95℃兩種(zhong)，電纜敷設溫度不低于0℃。

電(dian)(dian)纜(lan)的推薦允(yun)許彎(wan)曲半徑(jing)如(ru)下(xia)：無鎧裝(zhuang)電(dian)(dian)纜(lan)，應(ying)不低(di)(di)(di)于電(dian)(dian)纜(lan)外(wai)徑(jing)的6倍；鎧裝(zhuang)或(huo)銅帶屏蔽電(dian)(dian)纜(lan)，應(ying)不低(di)(di)(di)于電(dian)(dian)纜(lan)外(wai)徑(jing)的12倍；屏蔽軟電(dian)(dian)纜(lan)，不低(di)(di)(di)于電(dian)(dian)纜(lan)外(wai)徑(jing)的6倍。
