1.1 单芯电缆平行敷设时中心距离:185mm2及以下为电缆直径的2倍,240mm2及以上为90mm.。
The single-core cables are parallel laid,the distance between the cable center is 2 times of the cable diameter for cross-section area of conductor≤185mm2and 90mm for cross-sectional area of con-ductor≥240mm2
1.2 周围环境空气温度：40℃
Ambient temperature : 40℃
1.3 导体的长期最高工作温度：70℃（PVC）90℃（XLPE）
Max.long-run working temperature of conductor: 70℃（PVC）90℃（XLPE）
2、直埋敷设Direct-buried laying
2.1单芯电缆不接触敷设时，电缆中心距离为电缆直径的2倍。
The single-core cables are installed separately,the distance beween the cable centers is 2 times of the cable diameter
2.2土壤温度Soil temperature：25℃
2.3导体的长期最高工作温度70℃（PVC）90℃（XLPE）
Max.long-run working temperature of conductor：70℃（PVC）90℃（XLPE）
2.4土壤温度系数Soil thermal resistivity：1.0℃.m/w
2.5直埋深度Burial depth:0.7m
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。
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电缆穿管敷设时，管道内径不小于电缆外径的1.5倍,多根电缆穿管时禁止电缆拧绞挤压,管道有足够的容量，要求电缆的总面积不超过管内总面积的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电缆敷设最低温度不低于0℃,弯曲半径不小于20倍。
During installation min. ambient temperature shall be no less than 0℃ and bending radius is not less then 20 times of diameter.
3.4 当采用牵引导体夹头方式敷设时，允许最大牵引力为P=OA(N),A导体截面. O为50N/mm2(铜)和30N/mm2(铝)。
The Max permissible pulling force is P=0A(N) during installation with conductor pulling head. A: cross-section of conductor O:50N/mm2(CU) and 30N/mm2(AI)
4、试验 Test
安装结束后电缆不带负荷下进行绝缘电阻测试，必要时可进行交流工频耐压试验，历时1min.
Insulation resistance test without load shall be conducted after installation. The H.V. test shall last for 1 min when necessary.
