BV line, BVR line, RVSP double stranded shielded cable, RVS double stranded cable, RVB parallel line, RV line RVSP Shielded twisted-pair cable RVSP (shielded twisted-pair cable, shielded cable, shielding twisted-pair electric (HYVP, RVVP) RVVP twisted-pair shielded cable < < shielded wire > > is shielded twisted-pair cable RVSP series on the basis of RVS coupled with a layer of copper wire shielding net, so the transmission loss, shielding the outside world better than RVS series, but because of the copper wire shielding network, its cost is also much higher than RVS series. Are often used to those who has a high requirement on the transmission. Technical indicators: polyvinyl chloride insulated cable long-term allowed working temperature over 70 ℃, the cable temperature under installation should not below 0 ℃, outer diameter (D) is less than 25 The allowable bending radius of mm cable shall not be less than 4 times the outer diameter of the cable.

视频信号传输线有同轴电缆(不平衡电缆)、平衡对称电缆(电话电缆)、光缆。
平衡对称电缆和光缆一般用于长距离传输,对于宾馆酒店等建筑一般采用同轴电缆传输视频基带信号的传输方式。
当采用75-5同轴电缆时,一般传输距离在300m时,应考虑使用电缆补偿器。
氟塑料绝缘和护套耐高温控制电缆采用聚全氟乙丙稀或改性聚四氟乙烯材料,具有比普通控制电缆更高的耐热等级。

②识别灯标。
用规定的莫尔斯电码间歇地发出绿色闪光。
在一个地区有几个机场时,每个机场设一个,发出不同电码以示区别。
③进近灯。
又名下滑灯。
按照跑道类别,由十几个至一百多个灯组成进近灯光系统,帮助驾驶员对准跑道、调整飞机姿态和判断到跑道入口的距离;有时还在进近灯光系统的中线上加装一组由脉冲氙灯组成的顺序闪光灯。

主要用于火灾报警、消防设备、排烟设备、以及紧急通道运输、照明等应急设施的供电线路中需要耐火的场合。
(4)电缆安装时的最小弯曲半径:a、低烟无卤阻燃、耐火控制电缆:无铠装层的电缆应不小于电缆外径的6倍,有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。

一些的使用技巧包括程序的组织和功能的实现两部分,程序组织方面,要试着理解FFDB这些块的功能,了解系统OB的含义和用法,尝试着把程序按照块来组织,通过调用减少重复工作,提高复用性,使程序更清晰可读,这是提高编程水平,组织大型程序的基础。
功能实现方面,学习和了解一些常用的编程模式很有必要,比如顺序转换的编程结构,PID调节、步进电机控制等一些功能的原理、实现方法以及系统内置的工艺模块的用法,有可能的话尝试自己不用系统块写一个PID调节或者运动控制的功能,这些都是从熟手到高手的分水岭。
