2、照(zhao)(zhao)(zhao)明(ming)(ming)(ming)電氣照(zhao)(zhao)(zhao)明(ming)(ming)(ming)根據冷(leng)(leng)庫的安裝(zhuang)條件(jian)可分(fen)為(wei)一般照(zhao)(zhao)(zhao)明(ming)(ming)(ming)和(he)局部照(zhao)(zhao)(zhao)明(ming)(ming)(ming)。前者用于(yu)照(zhao)(zhao)(zhao)明(ming)(ming)(ming)整個區域，而后(hou)者僅用于(yu)照(zhao)(zhao)(zhao)明(ming)(ming)(ming)局部的某個工作場(chang)所。一般照(zhao)(zhao)(zhao)明(ming)(ming)(ming)和(he)局部照(zhao)(zhao)(zhao)明(ming)(ming)(ming)經常混合使用。特殊車間(jian)或(huo)(huo)工作場(chang)所也有應(ying)急(ji)照(zhao)(zhao)(zhao)明(ming)(ming)(ming)。當普通照(zhao)(zhao)(zhao)明(ming)(ming)(ming)發生故障并熄滅(mie)時，應(ying)急(ji)照(zhao)(zhao)(zhao)明(ming)(ming)(ming)可確保冷(leng)(leng)庫安裝(zhuang)人員撤離或(huo)(huo)不中(zhong)斷他們的工作。如果車間(jian)內有爆炸(zha)危險，應(ying)配(pei)備應(ying)急(ji)照(zhao)(zhao)(zhao)明(ming)(ming)(ming)。

3、電(dian)纜(lan)(lan)(lan)(lan)(lan)(lan)(lan)(lan)的(de)一(yi)根或幾根導線的(de)線芯包好相應的(de)絕(jue)緣層后，再包一(yi)層密封護(hu)套(tao)(鋁、鉛或塑料等。).這種電(dian)線叫做電(dian)纜(lan)(lan)(lan)(lan)(lan)(lan)(lan)(lan)。在冷庫安裝工程(cheng)中(zhong)，電(dian)纜(lan)(lan)(lan)(lan)(lan)(lan)(lan)(lan)一(yi)般分(fen)為動(dong)力(li)電(dian)纜(lan)(lan)(lan)(lan)(lan)(lan)(lan)(lan)和(he)控(kong)制電(dian)纜(lan)(lan)(lan)(lan)(lan)(lan)(lan)(lan)。電(dian)纜(lan)(lan)(lan)(lan)(lan)(lan)(lan)(lan)用于(yu)傳輸和(he)分(fen)配高功率(lv)電(dian)能。控(kong)制電(dian)纜(lan)(lan)(lan)(lan)(lan)(lan)(lan)(lan)用于(yu)連接冰箱(xiang)和(he)其他設備的(de)控(kong)制線。電(dian)纜(lan)(lan)(lan)(lan)(lan)(lan)(lan)(lan)架空敷設、埋地(di)(di)敷設和(he)地(di)(di)溝敷設。

4、機(ji)房布(bu)線(xian)(xian)(xian)(xian)機(ji)房布(bu)線(xian)(xian)(xian)(xian)是從配電(dian)箱(或控(kong)制箱)到電(dian)機(ji)的供電(dian)和(he)控(kong)制線(xian)(xian)(xian)(xian)路，有明配和(he)暗配兩(liang)種布(bu)線(xian)(xian)(xian)(xian)。電(dian)線(xian)(xian)(xian)(xian)沿墻(qiang)壁(bi)(bi)、天花板(ban)(ban)、梁、柱等(deng)以(yi)開(kai)放的方式敷設(she)，稱為(wei)(wei)開(kai)放式分布(bu)。埋(mai)在墻(qiang)壁(bi)(bi)、地板(ban)(ban)或天花板(ban)(ban)中的電(dian)線(xian)(xian)(xian)(xian)稱為(wei)(wei)暗配。按布(bu)線(xian)(xian)(xian)(xian)方式分，通常有瓷(塑(su))膠合板(ban)(ban)布(bu)線(xian)(xian)(xian)(xian)、瓷瓶(ping)布(bu)線(xian)(xian)(xian)(xian)、槽(cao)板(ban)(ban)布(bu)線(xian)(xian)(xian)(xian)、鋼管(guan)或塑(su)料管(guan)布(bu)線(xian)(xian)(xian)(xian)、鋁卡布(bu)線(xian)(xian)(xian)(xian)和(he)鋼索布(bu)線(xian)(xian)(xian)(xian)等(deng)。對布(bu)線(xian)(xian)(xian)(xian)的基本要(yao)求是：不僅(jin)要(yao)有可靠的電(dian)力傳輸，還要(yao)有合理(li)整潔的安(an)裝布(bu)局和(he)牢固(gu)的安(an)裝冷(leng)庫工程。
