6KV及以上电缆接头： ①安装电缆终端头时，必须剥除半导体电屏蔽层，操作时不得损伤绝缘，应避免刀痕凹凸不平的情况，必要时用砂纸磨平；屏蔽端部应平整，并要把石墨层（碳粒）清除干净。 ②塑料绝缘电缆端头铜带屏蔽和钢铠必须良好接地，对短路也遵循这项原则，避免三相不平衡运行时钢铠端部产生感应电动势，甚至“打火”及燃烧护套等事故。

今天就讲解一下接触器自锁到底怎么接线？在了解接触器自锁的接线以前，我们首先要了解接触器的原理，还有常开常闭触点，不知道这些我们接线还是一窍不通，下面我们先讲解一下接触器它的原理构造。380伏交流接触器有三个主触头也就是电源进线和负载端出线，进线分别是三相火线L1L2和L3,负载端出线分别是T1T2和T3,接触器主触头进线和出线上下一一对应，分别是L1对应T1,L2对应T2L3对应T3,主触头在接触器不吸合的状态下是常开状态什么是常开？常开的意思就是说触点是断开的，不联通的，常闭的意思就是说触点是联通的，常开和常闭一定要充分理解才可以接触器还有一个常开辅助触头，也就是右方的第四个接触器触点，上下也是一一对应，接触器不吸合一直是常开状态，辅助触头的作用就是辅助按钮控制接触器的，而主触头的作用是控制负载端的，所以分为主触头和辅助触头。

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 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 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.
To cable, we choose high electrical insulation materials production, such as special cable 1.8/3 kv frequency conversion motor, with 10 kv crosslinked insulating materials, special cable adopts frequency conversion motor of 6/10 kv, 35 kv crosslinking insulation materials, conductive shielding, insulation shield and insulation adopts the imported materials. In production, we put special emphasis on the purification of raw materials, shielding and insulating material key, control the uniformity of the insulation eccentricity and insulation outside diameter, which can interface effect, cable electrical properties.
