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是電纜設計用的導體對地或金屬屏蔽之間的額定工頻電壓,U是電纜設計用的導體間的額定工頻電壓,Um是設備可承受的最高系統電壓的最大值。

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根據電纜的敷設環境及負荷的不同，正確設計選擇電纜的型號規格。非鎧裝型適用于架空、室內、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在產生磁性管道中。易燃易暴、化學腐蝕性及高溫、低溫等場合應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，應規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境中且電纜盤不能平放。運輸時應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。

While storage, avoid the package long-term exposure ~and keep both ends well sealed. It is not permissible to keep cable in moisture places for long time ~or the cable drum flat. During transportation the drum must be properly fixed and  hoisted one at a time. Dropping drums from high position is strictly forbidden.

3、敷設安裝Installation

3.1電纜敷設應采用專用工具，如放線架、導輥等，敷設過程中防止機械損傷，遠離熱源。

 Special tools like paying-off rack ~and rollers shall be used during installation. Keep clear of heating source in case of mechanical injury. 

3.2電纜穿管敷設時，管道內徑不小于電纜外徑的1.5倍,多根電纜穿管時禁止電纜擰絞擠壓,管道有足夠的容量，要求電纜的總面積不超過管內總面積的40\%.

Inner radius of duct shall be not less than 1.5 times of cable diameter during installation in duct. When huclti-cables being laid in duct forbid to twist ~and pressure cables. The space inside duct shall be sufficient. The total area of cable requested shall be less than 40\% of total duct space

3.3電纜敷設最低溫度不低于0℃,彎曲半徑不小于20倍。
