  塑料绝缘和护套耐火电力电缆一、产品特点及用途:本产品具有较高的耐火性能,在火焰燃烧情况下,一定时间内不发生短路和断路故障。因此,当火灾发生时能在一定时间内,能保障关键部位正常供电,有利于灭火及减小损失。

模拟量传感器的接线有些麻烦,有两线制的,有四线制的,现在国内都用三线制的。两线制传感器是指,电源和信号共用两根线,四线制传感器是电源和信号分别用两根线。三线制是在四线制的基础上把电源的负于信号的负短接在一起,所以只有三根线。西门子S7-200/S7-200smart/s1200一般是四线制的,即电源和信号分开,且在硬件配置里可以选择信号类型。3有一些特定的模拟量需要使用特定的设备或者模块接收,PLC一般可以接受4-20ma,0-10V等等,而检测高温的热电偶或者称重传感器等因为工作原理,一般只有mv级别的电压信号,所以需要使用特定的模块或者仪表进行转换,这一点也需要经验去积累。

  电缆型号、名称、规格及用途:MHYV(PUYV)聚乙烯绝缘阻燃聚氯乙烯护套矿用信号电缆2-57/0.28用于平巷、斜巷及机电耍硐室MHJYV(PUJYV)聚乙烯绝缘阻燃聚氯乙烯护套加强矿用通讯电缆2-57/0.28(三钢四铜)用于平巷、斜巷、有较好的抗拉强度MHYVP煤矿用聚乙烯绝缘编织屏蔽聚氯乙烯。

Flame retardant cables and fireproof cables: the difference between the average person is very easy to confuse the concept of flame retardant cables and fireproof cables, although there are many more flame retardant cable applies to the advantages of chemical enterprise, such as low, low smoke, non-halogen, but in general, fire-resistant cable can replace flame retardant cable, and flame retardant cables can't take place of fire-resistant cable.
  合格标准为火焰不可蔓延到12英尺高的房间的上部。干线级电缆没有烟雾浓度规范,一般用于楼层垂直和水平布线使用。◎商用级-CM级(垂直燃烧测试VertialTrayFlameTest)这是UL标准中商用级电缆(GeneralPurposeCable),适用安全标准为UL1581。

  对称射频电缆主要用在低射频或对称馈电的情况中。(3)螺旋射频电缆同轴中的导体,有时可做成圈状,借以增大电缆的电感,从而增大了电缆的波阻抗及延迟电磁能的传输时间,前者称为高阻电缆,后者称为延迟电缆。如果螺旋线圈沿长度方向卷绕的密度不同,则可制成变阻电缆。
