　　煤矿用控制电缆允许的弯曲半径：对有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。对有屏蔽层结构的软电缆，应不小于电缆外径的6倍。对无铠装层的电缆应不小于电缆外径的6倍。产品在全国几十个煤业集团及矿山上使用，获得了较高的评价和赞誉。
With the same negative level transmission, when in the light, their impact on the two wires are the same, thus reducing difference at the receiving end can block this (minus operation performed can be understood as a difference of two way). It can be seen from the principle of double stranded lines that the purpose of double stranded lines is to transmit. Therefore, when we make the joint of the twisted pair, we must not separate the two different transmission lines, otherwise it will greatly affect the transmission of the network.

　　本补偿导线一般用聚氯乙烯绝缘和护套补偿导线或电缆具有优良的防潮、耐磨及阻燃特性；耐高温氟塑料绝缘和护套补偿导线或电缆采用连续挤出工艺，更有耐高温、耐寒、耐酸碱油水、不延燃、抗老化等优越性，产品质量高于国标GB/T等效采用IEC584-3)的规定。



　　3、低传输阻抗，电磁兼容性好。4、低工作电容。5、良好的抗干扰和低辐射性能。6、对称的三芯电缆结构设计，具有比四芯电缆更好的传输性能。7、具有较强的耐电压冲击性，能经受高速、频繁变频时的脉冲电压。8、具有良好的屏蔽性能，可降低变频器输出中存在的高次揩波的不良影响。

串联接线这种接线应用广，也普遍，因为布线方便。但是问题来了，接线的时候是把两线破皮后插入接线柱再拧紧螺丝还是把两线铰接在一起插入接线柱再拧紧螺丝？看起来都接上了，但是效果却差别很大。1，如果电工师傅按前者的方式接线，没有把导线铰接在一起。一个插座坏掉了。接线柱位置有可能烧坏，两根导线分离，后面串的插座全部断电。2，铰接到一起的，涮锡后插入，这样即使接线柱烧坏，两根导线还是连在一起，不影响后面的插座。

RS485 bus due to its wiring is simple, stable and reliable and widely used in video surveillance, access control intercom, building alarm and other fields, however, because there are a lot of in the process of 485 bus wiring is not completely accurate concept leads to many problems. Some wrong ideas will now be clarified.

下面说说三菱PLC在ST语言下的一些不足：只能声明一维数组三菱PLC只能声明一维数组，这对编程人员来说有了很大的限制。像西门子、倍福、施耐德都是可以声明多维数组的：上图是门子博图软件声明的一个三维int数组，如果三菱支持这个功能，上面蜘蛛纸牌的程序中BEHIND_LINE[ii].Numb[jj]就不必写成结构体+数组的形式，直接写成一个二维数组BEHIND_LINE[ii,jj]就可以了。只能建立一层结构体在三菱的结构体中只能声明基本类型的标签，无法声明其他的结构体，这也注定了三菱不能像施耐德和西门子那样完成复杂的逻辑功能。
