六、电缆安装使用 Cable installation ~and application

1、电缆的选择Cable selection 

 1.1电缆的额定电压U₀/U(Um)示为:UO是电缆设计用的导体对地或金属屏蔽之间的额定工频电压,U是电缆设计用的导体间的额定工频电压,Um是设备可承受的最高系统电压的最大值。

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根据电缆的敷设环境及负荷的不同，正确设计选择电缆的型号规格。非铠装型适用于架空、室内、隧道、电缆沟等场合，不能承受机械外力作用；铠装型同非铠装适用的条件外可直埋于地下，能承受一定的机械外力作用。单芯电缆不允许敷设在产生磁性管道中。易燃易暴、化学腐蚀性及高温、低温等场合应选择特殊型号的电缆。

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、储存和运输 Storage ~and transportation

电缆在储存中，应规范包装避免长期露天阳光暴晒，两端头可靠密封，不允许长期存放与潮湿的环境中且电缆盘不能平放。运输时应考虑盘高并有效固定，吊装时不允许几盘同时吊装，严禁从高处推下。

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、敷设安装Installation

3.1电缆敷设应采用专用工具，如放线架、导辊等，敷设过程中防止机械损伤，远离热源。
