Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the direct buried depth of 1-35kv cable is less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. ? 6KV and above cable connector:? When installing the terminal head of the cable, the semiconductor electrical shielding layer must be stripped off. During operation, the insulation shall not be damaged. The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, oid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. ? The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic requirements for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent water and other corrosive materials from corroding, in order to prevent the water tree caused by the aging of the insulation layer and breakdown. Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to oid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. ? Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.

电力电缆用途：用于传输和分配电能的电缆。常用于城市地下电网、发电站的引出线路、工矿企业的内部供电及过江、过海的水下输电线。在电力线路中，电缆所占的比重正逐渐增加。

电力电缆是在电力系统的主于线路中用以传输和分配大功率电能的电缆产品，其中包括1-500KV以及以上各种电压等级，各种绝缘的电力电缆。

电力电缆的基本结构：由线芯（导体）、绝缘层、层和保护层四部分组成（1）线芯 线芯是电力电缆的导电部分，用来输送电能，是电力电缆的主要部分。（2）绝缘层 绝缘层是将线芯与大地以及不同相的线芯间在电气上彼此隔离。 （3）层15KV及以上的电力电缆一般都有导体层和绝缘层，***电能输送，是电力电缆结构中不可缺少的组成部分。（4）保护层 保护层的作用是保护电力电缆免受外界杂质和水分的侵入，以及防止外力直接损坏电力电缆。

　　电力电缆保护层保护层的作用是保护电力电缆免受外界杂质和水分的侵入，以及防止外力直接损坏电力电缆。电力电缆优点多，占地少。一般埋设于土壤中或敷设于室内，沟道，隧道中，线间绝缘距离小，不用杆塔，占地少，基本不占地面上空间。
