因为耐火电缆的耐火层，通常采用多层云母带直接绕包在导线上．它可耐长时间的燃烧，即使施加火焰处的高聚物被烧毁，也能够保证线路正常运行。3.优缺点阻燃电缆、无卤电缆、耐火电缆的明确概念及优缺点阻燃电缆的特点是延缓火焰沿着电缆蔓延使火灾不致扩大。
三菱pIc的传送指令MOV,和比较指令CMP程序设计中最常用的指令。学会掌握这两个指令将会使程序设计更简单，设计出的程序更显智能化。MOV指令：MOV指令是功能指令中的基础指令，是最常用的指令。MOV传送指令简单说就是把一个值赋予另一个值。我们把被传送值叫源址S。那么S里有哪些操作数（被传送值）呢？它包括KnX，KnY，KnM，KnS，T，C，D，V，Z，K，H。被传送值传送到的地址为D。那么D有那些数值呢？KnY，KnM，KnS，T，C，D，V，Z。
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 square, tell from some cable, power cable according to the demand of power grid more generally for 5 core, and control cable transmission control, some more, according to the terms of more than 61 core, but also can produce according to user requirements.
每个电缆盘外侧应标明：a、制造厂名称或商标b、电缆型号及规格c、长度md、制造日期：年月e、标准编号f、毛重kg：g、表示电缆盘正确旋转方向的符号3、运输和保管a、线盘不允许平放b、运输中严禁从高处仍下装有电缆的电缆盘，严禁机械损失电缆。
2．电缆最高长期工作温度:阻燃聚氯乙烯绝缘及护套：70℃和105℃两种；交联聚乙烯绝缘：90℃；氟塑料绝缘和护套：200℃和260℃两种；氟塑料绝缘和105℃阻燃聚氯乙烯护套：105℃；无卤低烟阻燃聚烯烃绝缘和护套：70℃；无卤低烟阻燃聚烯烃绝缘和护套：90℃和125℃两种。
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.
