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 buried depth of 1-35kv cable is not 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 is not 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. 6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be cleaned. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and accidents such as burning sheath. 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 re 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 erosion of water and other corrosive materials, so as to prevent breakdown due to the aging of the insulation layer caused by water trees. 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 avoid 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 done by the installation personnel or full-time technical personnel familiar with the performance of wire and cable. If there are still unclear matters, please consult the relevant technical department or the technical department of our factory.

1P漏电断路器和2P漏电断路器电线电线分为入户线、箱内配线和出线。三种线，三种规格，三类人员进行接线。入户线，一般使用6平方BV线，是建筑施工人员进行安装的。配电箱内接线，一般使用4平方BV线，是配电箱厂家进行安装的，建筑施工人员只负责将配电箱放入墙内并连接入户线。这里多说一句，BVR线有时也用在配电箱内——不过只用作控制线，家用配电箱没有控制线，因此不出现BVR线。出线，也就是房间内的电线，由装修施工人员进行安装，接在配电箱的出线端。
