武漢冷庫工程已安裝的電氣安裝工程可包括架空線路、照明、電纜、機房布線、車間或廠區的變配電。

1、架空線(xian)(xian)(xian)路(lu)送電(dian)如果在長距離的情況下(xia)，經(jing)常使用室外架空電(dian)源。分為高壓(ya)和低壓(ya)兩種(zhong)，都是由電(dian)桿(金(jin)屬塔、鋼筋混凝土或(huo)木(mu)桿)和電(dian)線(xian)(xian)(xian)組成。1kv以下(xia)的低壓(ya)架空線(xian)(xian)(xian)，1kv以上的高壓(ya)架空線(xian)(xian)(xian)。

2、照(zhao)(zhao)明(ming)(ming)(ming)電氣(qi)照(zhao)(zhao)明(ming)(ming)(ming)根據冷庫的(de)安裝(zhuang)條件可分為一般(ban)照(zhao)(zhao)明(ming)(ming)(ming)和(he)(he)局(ju)部照(zhao)(zhao)明(ming)(ming)(ming)。前(qian)者(zhe)用(yong)于照(zhao)(zhao)明(ming)(ming)(ming)整個區(qu)域，而后(hou)者(zhe)僅用(yong)于照(zhao)(zhao)明(ming)(ming)(ming)局(ju)部的(de)某(mou)個工(gong)作場所。一般(ban)照(zhao)(zhao)明(ming)(ming)(ming)和(he)(he)局(ju)部照(zhao)(zhao)明(ming)(ming)(ming)經(jing)常混合使用(yong)。特殊車間(jian)或工(gong)作場所也有(you)應(ying)急照(zhao)(zhao)明(ming)(ming)(ming)。當普通照(zhao)(zhao)明(ming)(ming)(ming)發生(sheng)故障(zhang)并(bing)熄滅(mie)時(shi)，應(ying)急照(zhao)(zhao)明(ming)(ming)(ming)可確保冷庫安裝(zhuang)人(ren)員(yuan)撤離或不中斷(duan)他(ta)們的(de)工(gong)作。如果車間(jian)內(nei)有(you)爆炸(zha)危(wei)險，應(ying)配備應(ying)急照(zhao)(zhao)明(ming)(ming)(ming)。

3、電纜(lan)(lan)的一根(gen)或幾根(gen)導線的線芯包(bao)好相應的絕(jue)緣層(ceng)后，再包(bao)一層(ceng)密(mi)封護套(鋁、鉛或塑料(liao)等。).這種電線叫(jiao)做電纜(lan)(lan)。在(zai)冷庫安裝工程中，電纜(lan)(lan)一般分為動力(li)電纜(lan)(lan)和控制電纜(lan)(lan)。電纜(lan)(lan)用(yong)于傳輸和分配高功(gong)率電能。控制電纜(lan)(lan)用(yong)于連(lian)接冰箱和其他設備的控制線。電纜(lan)(lan)架空敷設、埋地敷設和地溝敷設。

4、機房布(bu)(bu)(bu)線(xian)機房布(bu)(bu)(bu)線(xian)是(shi)從配(pei)電(dian)(dian)(dian)(dian)箱(或(huo)控制箱)到電(dian)(dian)(dian)(dian)機的供(gong)電(dian)(dian)(dian)(dian)和(he)控制線(xian)路，有(you)明配(pei)和(he)暗配(pei)兩種(zhong)布(bu)(bu)(bu)線(xian)。電(dian)(dian)(dian)(dian)線(xian)沿(yan)墻壁、天花板(ban)(ban)(ban)(ban)、梁、柱等以開(kai)放(fang)的方式(shi)敷(fu)設，稱(cheng)為開(kai)放(fang)式(shi)分(fen)布(bu)(bu)(bu)。埋在墻壁、地板(ban)(ban)(ban)(ban)或(huo)天花板(ban)(ban)(ban)(ban)中的電(dian)(dian)(dian)(dian)線(xian)稱(cheng)為暗配(pei)。按(an)布(bu)(bu)(bu)線(xian)方式(shi)分(fen)，通常(chang)有(you)瓷(塑)膠合(he)板(ban)(ban)(ban)(ban)布(bu)(bu)(bu)線(xian)、瓷瓶布(bu)(bu)(bu)線(xian)、槽板(ban)(ban)(ban)(ban)布(bu)(bu)(bu)線(xian)、鋼管或(huo)塑料管布(bu)(bu)(bu)線(xian)、鋁卡布(bu)(bu)(bu)線(xian)和(he)鋼索布(bu)(bu)(bu)線(xian)等。對布(bu)(bu)(bu)線(xian)的基本要求是(shi)：不僅要有(you)可靠的電(dian)(dian)(dian)(dian)力傳輸(shu)，還(huan)要有(you)合(he)理整潔的安裝布(bu)(bu)(bu)局(ju)和(he)牢(lao)固的安裝冷庫(ku)工程。

5、變(bian)壓(ya)器和(he)(he)配(pei)電(dian)(dian)設(she)(she)備(bei)(bei)。變(bian)配(pei)電(dian)(dian)設(she)(she)備(bei)(bei)是用于轉換電(dian)(dian)源(yuan)和(he)(he)分配(pei)電(dian)(dian)能的(de)電(dian)(dian)氣裝(zhuang)置(zhi)。它由(you)變(bian)壓(ya)器、開關設(she)(she)備(bei)(bei)、保護裝(zhuang)置(zhi)、測量儀器、連接母線和(he)(he)電(dian)(dian)纜組成。有(you)兩種配(pei)電(dian)(dian)方式：室(shi)內和(he)(he)室(shi)外(wai)(wai)(wai)。室(shi)內電(dian)(dian)壓(ya)較低，一般(ban)在35kV以(yi)下(xia)，室(shi)外(wai)(wai)(wai)電(dian)(dian)壓(ya)一般(ban)在35kV以(yi)上。但(dan)一些(xie)6-10kV電(dian)(dian)壓(ya)的(de)小(xiao)功率終端配(pei)電(dian)(dian)設(she)(she)備(bei)(bei)往(wang)往(wang)安裝(zhuang)在室(shi)外(wai)(wai)(wai)。通(tong)用冷庫工程變(bian)配(pei)電(dian)(dian)設(she)(she)備(bei)(bei)多在室(shi)內。
