煤矿用阻燃通信电缆一、执行标准：MT818.14—1999和《煤矿用阻燃通信电缆检验细则》二、产品命名代号煤矿用阻燃通信电缆…………………………………MH聚乙烯绝缘……………………………………………Y铜质线芯………………………………………………省落铝—聚乙烯粘结护层…………………………………A聚乙烯。
IEC/BS4066-1阻燃等级（单根电线或电缆垂直燃烧测试FlameTestONSingleVerticalInsulatedWires/Cables）这是单根电缆的阻燃标准。IEC/BS4066-3阻燃等级（成束电线或电缆垂直燃烧测试FlameTestOnBunchedWires/Cables）这是成束电缆的阻燃标准。
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。
1) production time: the goods will be delivered on the same day as soon as they are available in stock, and the to be customized shall be determined. 2) sales discount: large is preferred. 3).

下面简单的介绍一下指针式万用表的使用注意事项；量程转换开关必须拨在需要测量的档位上，不能放错，如果测量电压时误将转换开关拨在电流档或者电阻档，则将会损坏万用表。在测量电流或电压时，如果对于被测电流、电压大小心中没有数，应该先拨到大量程上，以确保指针（表头）不至于打坏，然后再拨到合适的量程上测量，以减小误差。但是切记不可以带电转换量程开关。在测量直流电压或直流电流时，必须注意万用表表笔的极性。正负端应各与电路的正负端相接。
Main characteristics of the mine cable fire with fire temperature in 600 ℃ ~ 8000 ℃, the fire cases, the cable will soon lose insulating ability, thus cause the secondary electrical accidents such as short circuit, causing a greater loss. The wire and cable have greater overload capacity under the specified allowable load flow. In a short circuit, the wire and cable will instantly cause the insulation to melt and ignite the surrounding area.
八、电缆的规格及参考数据见表5-12WDZ-KYJY交联聚乙烯绝缘聚烯烃护套阻燃低烟无卤控制电缆WDZ-KYJY22交联聚乙烯绝缘钢带铠装聚烯烃护套阻燃低烟无卤控制电缆表WDZN-KYJY交联聚乙烯绝缘聚烯烃护套阻燃耐火低烟无卤控制电缆WDZN-KYJY22交联聚乙烯绝缘钢带铠装聚烯烃护套阻燃耐火低。
7、自承式电缆：采用8字形挤出模具，对自承钢索与铝塑纵包缆芯同时挤塑。 8、铠装（适用于铠装电缆23、22、53型）；在综合护层外绕包两层镀锌钢带（适用于23、22型电缆）或纵包一层涂塑钢带（适用于53型电缆）。
Sheathed control cable insulation resistance: each conductor and the rest of the grounding wire core, control cable is more than 10000 m Ω. Km, more than 3000 m Ω HYAT cable. Km.
Communication cables are cables that transmit telephone, telegraph, facsimile documents, television and radio programmes, data and other electrical signals. Twisted by more than one pair of mutually insulated conductors. Compared with overhead open line, communication cable has the advantages of large communication capacity, high transmission stability, good confidentiality, less affected by natural conditions and external interference.

万用表是可以用来测量电流的，用万用表测量电流的时候也是要分直流和交流的。下面以胜利数字万用表分别说明：如果是维修电子电路板，大多是测量直流电流，而且大部分是低压，小电流为主。如图。先估算大概的电流，选好测量档。黑表笔插COM，红表笔根据测量的大小，选择左边的mA小电流档大200mA，左边的20A大电流档。将要测量的电路回路中的某个点断开，将表两表笔串联在电路中。如果电流从黑表笔进，电表显示的是负数。
