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)計用的導(dǎo)體對地或金屬屏蔽之間的額定工頻電壓,U是電纜設(shè)計用的導(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)境及負荷的不同，正確設(shè)計選擇電纜的型號規(guī)格。非鎧裝型適用于架空、室內(nèi)、隧道、電纜溝等場合，不能承受機械外力作用；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、低溫等場合應(yīng)選擇特殊型號的電纜。

Cable types must be properly selected ~and designed in light of different installing places ~and loads. Not withstanding much mechnical force, non-armoured cables are often used in aerial line, tuunel, cable trench ~and indoors. Armoured type, aside from mentioned places, can be buried underground ~and bear mechanical forces. No single-core cable is allowed to be laid in magnctiable duct. Special cables should be chosen ~where goods are easily combusted ~and exploded ~and occasions with low ~or high temperature ~and chemical corrosion.

2、儲存和運輸 Storage ~and transportation

電纜在儲存中，應(yīng)規(guī)范包裝避免長期露天陽光暴曬，兩端頭可靠密封，不允許長期存放與潮濕的環(huán)境中且電纜盤不能平放。運輸時應(yīng)考慮盤高并有效固定，吊裝時不允許幾盤同時吊裝，嚴禁從高處推下。
