Insulating material: high density polypropylene or polypropylene, colour of the insulated wire as indicated by full chromatograph. Pair of insulated wires: twist two different colored insulated wires into pairs at different pitch and use the specified chromatographic combination to identify pairs. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs of cables with more than one pair of cables plus 1% of the reserve pair, but not more than 6 pairs. The gap in the core is filled with oil paste. Core tape: wrap with a polygrease film tape. Shielding: metal strip with or without striping, which is longitudinal wrapped outside the core of the cable. Sheath: black low density polymer. Double sheathed cables can also be provided. Identification and marking: cable outer surface sexual identification mark, mark at no more than alternate 1 m intervals, tag contents are: the diameter of wire, line number, cable type, factory name and year of manufacture, marking at no more than alternate 1 m intervals to mark on the surface, but with the tag stagger. Other structures: according to the needs of users, we can provide armored cables HYAT53, HYAT55 and high frequency isolation cables YATG with strengthened mechanical protection layer.

PLC是由继电控制引入微处理技术后发展而来的，可方便及可靠地用于开关量控制。由于模拟量可转换成数字量，数字量只是多位的开关量，故经转换后的模拟量，PLC也完全可以可靠的进行处理控制。由于连续的生产过程常有模拟量，所以模拟量控制有时也称过程控制。模拟量多是非电量，而PLC只能处理数字量、电量。所有要实现它们之间的转换要有传感器，把模拟量转换成数电量。如果这一电量不是标准的，还要经过变送器，把非标准的电量变成标准的电信号，如4—20m1—5V、0—10V等等。

　　用途：耐火电缆广泛应用于高层建筑、地下铁道、地下街、大型电站及重要的工矿企业等与防火安全和消防救生有关的地方，例如，消防设备及紧急向导灯等应急设施的供电线路和控制线路。 2.电缆敷设安装允许弯曲半径非铠装电缆应不小于电缆外径的10倍；铠装电缆应不小于电缆外径的15倍。

　　4．电缆安装敷设温度应不低于0℃5．耐火特性：符合IEC60331规定符合GB/T规定火焰温度750℃火焰温度750℃燃烧时间3h燃烧时间90min冷却时间12h附加电压额定电压附加电压额定电压附加电流2A附加电流3A6．敷设推荐的允许弯曲半径：非铠装、联锁或编织铠装电缆应不小于电缆外径的6倍铜带屏。

　　试验规定，一根60cm长的试样垂直固定在前壁开通的金属箱内，火焰长度175mm的丙烷燃烧器从距试样的上部固定端450mm的位置上火焰锥与电缆以45度角接触，如果试样燃烧损坏部分距离固定端下部不超过50mm，测试通过。

　　合理的结构设计，严格的选材，精良的生产加工，严格的质控程序，保证产品在实际应用中效果良好。三、使用条件：1、电缆仅用于建筑物内，且环境温度应保持在5-40℃范围内。2、正常使用时，导体高温度为70℃。

PLC硬件部分的设置如下：因为采集的是电压输入（0-5V），所以要处于OFF状态，这里要结合CJ1W-MAD42，可以去欧姆龙官网进行下载。下面这部分是为了设置欧姆龙plc中硬件输入的电压范围（0-10V）分辨率是4000，分辨率就是模拟量对应的数值量。上图中，这是在编程软件中设置通道模拟量的输入范围，而我这个实际在程序中也进行了设置，后来我和欧姆龙官网的技术人员沟通过，他们说只需要在这个地方进行设置就好了，你们以后可以就这样操作，不需要在程序中进行赋值了。
