道平行安装时应保持2m的间距，交叉时应保持0.5m。

2.电缆与其它管道平行或交叉安装时均要保持0.5m的间距。3.电缆直埋安装时，1-35kV电缆直埋深度应不小于0.7m。4.多根电缆平行安装时相互净距不小于电缆直径。

5.电缆安装时的最小弯曲半径：多芯电缆不得低于15D，单芯电缆不得低于20D(D为电缆外径)。6.额定电压6kV及以上电缆接头：

6.1安装电缆终端、中间接头时，必须剥除半导电绝缘屏蔽层，操作时不得损伤绝缘，应避免刀痕及凹凸不平的情况，必要时要用砂纸磨平；屏蔽端部应平整，并要把可能沾附在绝缘层上的半导电屏蔽清除干净。建议使用冷缩型电缆终端、中间接头，并严格遵照接头厂家提供的产品说明书操作。

6.2塑料绝缘电缆端头铜屏蔽和

钢铠必须良好接地，对短线路也应遵循这项原则，避免三相不平衡运行时钢铠端部产生感应电动势，甚至“打火”及燃烧护套等事故。接地引出线要采用镀锡编织铜线，和电缆铜带连接时应用烙铁锡焊，不宜用喷灯封焊，以免烧损绝缘。

6.3三相铜屏蔽应分别与地线相连，注意屏蔽接地线和钢铠接地线应分别引出，焊接地线的位置应尽量靠下。

7.对电缆终端头和中间接头的基本要求：a.导体连接良好；b.绝缘可靠；c.密封良好；d.足够的机械强度，能适应各种运行条件。

8.电缆端头必须防水，以及其它腐蚀性材料的侵蚀，以防因水树引起绝缘层老化而导致击穿。

9.电缆的装卸必须使用吊车或叉车，禁止平运、平放，大型电缆安装时须使用放缆车和地滚，以免电缆受外力损伤或因人工拖动而擦伤绝缘层。

10.电缆如因故不能及时敷设时，应将其放在干燥地方贮存，防止日光曝晒、电缆端头进水等。

注意：电线电缆敷设、安装应由熟悉电线电缆性能的安装人员或专职技术人员担任，如仍有不清事项，请向相关技术部门或我公司咨询，电话：0871-8195149。

10、交联聚乙烯绝缘阻燃电力电缆10．1阻燃电缆的分类按国家标准GB12665.5-90《成束电线电缆燃烧试验方法》中规定-从成品电线电缆上截取式样，每根式样的长度为3.5m,式样的根数按成束电线电缆每迷长度所含非金属材料的不同体积分为三种类别:A类:式样根数应使每米所的非金属材料的总体积为7L。B类：式样根数应使每米所的非金属材料的总体积为3.5L。C类:式样根数应使每米所的非金属材料的总体积为1.5L。用喷灯火焰燃烧试样,A类和B类试样供火时间40min,C类试样供火时间20min,如试样炭化部分所达到的高度不超过2.5m,则判定试验结果为合格。A类阻燃最为严格，B类阻燃要求也很高，适用于对阻燃要求较为严格的场合，C类为一般阻燃，适用于大多数要求阻燃的场合。10．2交联聚乙烯绝缘阻燃电力电缆的型号C类：YJV-ZR型；YJLV-ZR型。B类和C类：YJV22-ZR型；YJLV22-ZR型；YJV32-ZR型；YJLV32-ZR型；YJV42-ZR型；YJLV42-ZR型。YJV62-ZR型；YJLV62-ZR型；YJV72-ZR型；YJLV72-ZR型；10．3交联聚乙烯绝缘阻燃电力电缆的电压等级、芯数、截面、结构、电缆特性及使用参数（载流量、短路电流）均与普通型交联聚乙烯绝缘电力电缆相同（祥见前面各表）。
