　　矿用电缆选择矿井供电系统中，高压供电线路一般都采用铠装电缆，其故障率相对低压供电所采用的[1]要少得多。采区供电是供电系统中的薄弱环节，工作环境又较差，因而如何选择电缆的型号与截面，关系到供电运行的安全。
　　电缆的安装与敷设：1． 电缆长期允许工作温度为-40～+50℃，月平均相对湿度为95％（+25℃时）；2． 电缆允许敷设与安装的温度应不低于-10℃；3． 电缆小弯曲半径：MHYVR型为电缆外径的10倍，其他型号为外径的15倍。

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.

　　GWDZR-X隔氧层低烟无卤阻燃电缆NH-X耐火电缆敷设在对耐火有要求的室内、隧道及管道中，GNH电缆除耐火外要求高阻燃的场所。GNH-X隔氧层耐火电缆WDNH-X低烟无卤耐火电缆敷设在有低烟无卤耐火要求的室内、隧道及管道中，GWDNH电缆除低烟无卤耐火特性要求外，对阻燃性能有更高要求的场所。

场效应分类：场效应管主要有结型场效应管（JFET）和绝缘栅型场效应管（IGFET）。绝缘栅型场效应管的衬底（B）与源析（S）连在一起，它的三个极分别为栅极（G）、漏极（D）和源极（S）。晶体管分NPN和PNP管，它的三个极分别为基极、集电极、发射极。场效应管的S极与晶体管的e极有相似的功能。绝缘栅型效应管和结型场效应管的区别在于它们的导电机构和电流控制原理根本不同，结型管是利用耗尽区的宽度变化来改变导电沟道的宽窄以便控制漏极电流，绝缘栅型场效应管则是用半导体表面的电场效应、电感应电荷的多少去改变导电沟道来控制电流。
