﹑专业面狭窄，作为一名电气工程师，应该是一专多能的，这样才符合公司发展的需求。在以后的工作过程中，加强其他专业的学习，从而提高自己的业务、技术水平，时时严格要求自己，注重自身发展和进步，做到谨小慎微。对于工作过程中的前瞻性、计划性不够强，在以后工作中提高自己对于会发生问题工作的预见性，尽量不出问题，当遇到问题时能做到有条不紊的处理。四﹑明年的工作展望明年会是更忙碌的一年，精品商务楼工程从3月份开工到封顶施工阶段，万力木雕文化广场工程9月30开工，接下来的工作中我将紧密围绕在公司的总体计划纲领下，切实可行的完成自己的工作，更加努力，更求进步，使自己的工作能力有更大的提高，做一名合格的万力员工，争取为公司创造更大的效益，在明年更好地完成工作。
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, avoid 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 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 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 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 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.

电缆端头必须使用防止水及其它腐蚀性材料的侵蚀，以防因水树引起绝缘层老化而导致击穿。电缆的装卸必须使用吊车或叉车，禁止平运，平放，大型电缆安装时须使用放缆车，以免电缆受外力损伤或因人工拖动而擦伤。电缆如因故不能及时敷设时，应将其放在干燥地方贮存，防止日光爆晒，电缆端头进水等。
2、绝缘材料：高密度聚乙烯或聚丙烯，按照全色谱标准标明绝缘线的颜色。3、绝缘线对：把二根不同颜色的绝缘线按不同的节距扭绞成对，并采用规定的色谱组合以便识别线对。4、通信电缆缆芯结构：以1对为基本单位，超过25对的电缆按单位组合，每个单位用规定色谱的单位扎带绕扎，以便识别不同的单位。

三相电源与单相电源的区别：发电机发出的电源都是三相的，三相电源的每一相与其中性点都可以构成一个单相回路为用户提供电力能源。注意在这里交流回路中不能称做正极或负极，应该叫线端（民用电中称火线）和中性线（民用电中称零线）。按照规定，380伏（三相）的民用电源的中性点是不应该在进户端接地的（在变压器端接地，这个接地是考虑到不能因悬浮点位造成高于电源电压的点位，用户端的接地与变压器端的接地在大地中是存在一定的电阻的），供电方式是一根火线和一根零线（中性点引出线）构成回路，在单相三芯的电源插孔中还接有一根接地线。
