摘　　要：电力电缆线同架空线路一样,都是电力网的重要组成部分,电力电缆线路的安全可靠性直接影响到电力系统的正常运行,因为很多电缆线路是敷设在地下的隐蔽工程,一旦出故障,检修恢复难度较大,危险性也大,直接影响对用户的供电。文章对电缆线路热伸缩危害进行了分析,并提出了消除措施。The important part of the power cables, overhead lines, the electricity grid, the safety and reliability of the power cables directly affect the normal operation of the power system, because a lot of cable lines are laid underground, hidden works, once the failure, repair restoration is difficult and risk a direct impact on the user＇s power supply. The article on the hazards of thermal expansion of cable lines, and eliminate measures.
