项目“弱电”一般是以“项目”或“工程项目”形式体现的，大到国家重点项目，小到智能家居项目。子项有些项目中虽然软件部分的份额比较大，但硬件系统工程部分仍属“弱电”范畴。过程项目是一个整体的过程，一般需要五个过程(环节)，在具体项目中也表现为前期、中期、后期三个阶段，同时每个项目都有生命周期。“弱电”可以称之为一个泛行业虽说没有明确“弱电行业”，但是民间已经逐渐把“弱电”看成是一个行业，只是概念比较模糊，我们暂且可以把“弱电”称之为一个泛行业，就是以“弱电”工程项目实施为主的电子智能工程行业。
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.

下面介绍几种抗干扰的措施：1.电源线设计。根据印制线路板电流的大小，尽量加租电源线宽度，减少环路电阻。同时、使电源线、地线的走向和数据传递的方向一致，这样有助于增强抗噪声能力。地段设计。地线设计的原则是：数字地与模拟地分开。若线路板上既有逻辑电路又有线性电路，应使它们尽量分开。低频电路的地应尽量采用单点并联接地，实际布线有困难时可部分串联后再并联接地。高频电路宜采用多点串联接地，地线应短而租，高频元件周围尽量用栅格状大面积地箔。
