  如采用75-9同轴电缆时,摄像机和监视器间的距离在500m以内可不加电缆补偿器。
为方便用户参考,将常用同轴电缆尺寸列表如下:表中尺寸均为标称尺寸,欲获取更详细的有关电缆的参数,请参考相关标准或制造商的说明。


在电力系统中三相发电机和变压器等设备具有良好的对称性,不会对三相电压不平衡产生影响,故电力系统阻抗的不平衡主要是由供电线路阻抗不平衡造成的,当三相导体(架空线或者电缆)程水平或垂直排列时,为了保持三相阻抗平衡,需要采取换相等措施。
三相电压不平衡造成的危害变压器处于负载不平衡运行时,某相电压处于满载,其余两相未满载,使变压器容量不能得到充分的利用,变压器长期处于负载不平衡运行时,造成其局部过热,降低其使用寿命。

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 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 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.

三相电源中流过每相负载的电流为相电流,用IAIBICA表示。
对于星型接法的电动机,相电流等于线电流,对于三角形接法的电动机,线电流等于根号3相电流在星形联接的负载中,流过端线的线电流等于流过负载的相电流,流过中线的中线电流等于各相电流的矢量和。
在三角形联接的负载中,相电压等于线电压(各相负载两端的电压仍称为相电压)。
一般总是三相负载对称的才接成三角形接法,此时三个线电流对称,三个相电流也对称,线电流等于相电流的“根号3”倍。
