Laying mode and construction technical requirements of cable line

電纜一般分電力電纜和控制電纜兩種，其基本特點是：一般埋設在地下，不易受外界的破壞及環境的影響，運行比較可靠，同時通過居民區無高壓危險。電纜線路節約用地，美化市容，便于管理，日常維修量小。但也存在施工復雜，價格較高，施工期長，敷設后不易更改，不易加分支線，不易發現故障，檢修技術復雜的不利影響。

Cables are generally divided into power cables and control cables. Their basic characteristics are: they are generally buried underground, not easy to be damaged by the outside world and affected by the environment, and they operate reliably. At the same time, they pass through residential areas without high voltage danger. The cable line saves land, beautifies the city appearance, is easy to manage, and has small amount of daily maintenance. But there are also some disadvantages, such as complex construction, high price, long construction period, difficult to change after laying, difficult to add branch lines, difficult to find faults and complex maintenance technology.
