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.

)施工质量控制。按照会审后的设计图纸和相关技术文件及有关工程建设法规、文件的总体设计方案进行，严格按图纸的施工要求保质保量的进行，若发现与图纸不一致的地方，不允许私自变更，应与设计师共同探讨解决，严格推行规范化、标准化、可操作化的质量控制程序;对各个子系统的施工质量、单体设备安装严控把关，做好各项系统和设备的测试和调试记录;对智能建筑弱电工程涉及到的外围设备和材料进行检验，凡无标志或标志不清的、对质量保证有怀疑的、与签署合同不相符材料需进行抽检，进口材料需要海关商检证明和产地证明资料，做好材料报审，经监理审核确认后方可施工。

　　 生产的品种有通信电缆与信号电缆两种，型号为MHYV。 通信电缆规格为1～80对，从井筒干线电缆到工作面用1～2对的电缆都齐全。 信号电缆为1～19对，可用于任何监控系统。 电缆具有阻燃、抗静电的性能，特别适合高瓦斯矿井使用。

Plastic insulated power cable insulation layer for plastic power cable. The commonly used plastics are polychlorinated, polychlorinated and poly. Plastic cable structure is simple, easy to manufacture and process, light weight, easy to install and lay. Therefore, it is widely used as medium - low - voltage cable, and has the tendency to replace the viscous impregnated oil-paper cable. Its major drawback is the existence of dendritic breakdown, which makes it used at higher voltage.

　　接地引出线要求采用我镀锡编织铜线，和电缆铜带连接时应用铬铁锡焊，不宜用喷灯封焊，以免烧损绝缘。③三相铜带屏蔽应分别与地线相连，注意屏蔽接地线和钢铠接地线应分别引出，相互绝缘，焊接地线的位置应尽量靠下。对电缆端头和中间接头的基本要求：a.导体连接好；b.绝缘可靠，推荐采用辐照交联热收缩型硅橡胶绝缘材料；c.密封良好；d.足够的机械强度，能适应各种运行条件。



　　MHYV（PUYV）（1×21×42×23×24×25×26×28×210×2）1/1.0、1/1.38聚乙烯绝缘聚氯乙烯护套煤矿用信号电缆用于矿场作普通信号传输，适用于固定敷设。MHYVRP7/0.30、7/0.37、7/0.43、7/0.52（1～10对、1×4）聚乙烯绝缘铜丝编织屏蔽聚氯乙烯护套煤矿用信号电缆，用于电场干扰较大的场所作信号传输，电缆较柔软。

The cross section of the control cable is generally no more than 10 square meters, and the power cable is mainly used to transport power, which is generally large. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section of the general factory is relatively less, you can do and control cable section generally small, generally not more than 10 largest square, tell from some cable, power cable according to the request of power grid, most commonly for five core, and control cable transmission control signal, some more, according to the standard terms of more than 61 core, but also can produce according to user re

尽管三件套的本身，在技术上不断进步，可谓日新月异。由使用模拟信号到数字信号；由CRT变成了液晶屏；由单色的变成了彩色的；有线连接变成无线连接，红外线，蓝牙技术等都用上了。这些都只是为了提高产品的质量，提高其经济性和实用性方面的进步。但是我们应该注意到，所有这一切并没有对这种人机界面的基本功能发生任何改变。因为它用来直接与人的眼和手交流信息的功能没有变。众所周知，计算机的操作系统由DOS演变成了Windows（当然还有其他的类似系统）。
