弱电线缆种类繁多，各个系统使用的电缆型号不同，功能不同，做弱电的朋友们有必要了解一下常用的弱电线缆。电线电缆的定义电线电缆是指用于电力、通信及相关传输用途的材料。“电线”和“电缆”并没有严格的界限。通常将芯数少、产品直径小、结构简单的产品称为电线，没有绝缘的称为裸电线，其他的称为电缆。弱电电缆命名原则产品名称中包括的内容：场合或大小类名称产品结构材料或型式；产品的重要特征或附加特征基本按上述顺序命名，有时为了强调重要或附加特征，将特征写到前面或相应的结构描述前。

　　现设办公室（政策研究室）、综合部（国际部、信息部）、技术部、评审部、检验部、监督部、财务部等部门。发展现状我国的矿用电缆经过几年的高速发展已形成相当的规模，但由于生产能力大于需求，出现供大于求的局面。目前的生产能力已大大超过今年的预测需求数值，同时电线电缆企业均面临亟待提高产品技术含量的问题。

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.

　　由于其成本较低，因此是防火电缆中大量采用的电缆品种。无论是单根线缆还是成束敷设的条件下，电缆知燃烧时能将火焰的蔓延控制在一定范围内，因此可以避免着火延燃而造成的重大灾害，从而提高电缆线路的防火水平。耐火电缆是在火焰燃烧情况下能保持一定时间的正常运行，可保持线路的完整性。

在plc编程中，只要涉及到数据采集和输出，都会遇到模拟量的线性变换。在西门子300plc编程中，系统自带的两个线性变换功能块FC105和FC106是常用的两个数据转换模块。FC105和FC106只适用与把采集通道的数字量（INT）转换为物理量（REAL），在一些普适的场合就不适用了。在碰到线性变换时，需要用户自己编写线性变换程序，费时费力还容易出错。本文简单介绍PLC中模拟量线性标定子程序的原理和方法。
