六、電纜安裝使用 Cable installation ~and application

1、電纜的選擇Cable selection 

 1.1電纜的額定電壓U₀/U(Um)示為:UO是電纜設(shè)計(jì)用的導(dǎo)體對(duì)地或金屬屏蔽之間的額定工頻電壓,U是電纜設(shè)計(jì)用的導(dǎo)體間的額定工頻電壓,Um是設(shè)備可承受的最高系統(tǒng)電壓的最大值。

Cable rated voltage U₀/U(Um) stand for: U₀  is rated A.C. voltage designed between candactor to earth ~or motellic sereen. U is rated A.C. voltage desighed  between phase to phase, Umis max system voltage which equipment can withstand.

1.2根據(jù)電纜的敷設(shè)環(huán)境及負(fù)荷的不同，正確設(shè)計(jì)選擇電纜的型號(hào)規(guī)格。非鎧裝型適用于架空、室內(nèi)、隧道、電纜溝等場(chǎng)合，不能承受機(jī)械外力作用；鎧裝型同非鎧裝適用的條件外可直埋于地下，能承受一定的機(jī)械外力作用。單芯電纜不允許敷設(shè)在產(chǎn)生磁性管道中。易燃易暴、化學(xué)腐蝕性及高溫、低溫等場(chǎng)合應(yīng)選擇特殊型號(hào)的電纜。
