绝缘：根据不同型号可采用阻燃聚乙烯、聚氯乙烯、聚乙烯三种中的一种.绝缘表面应光滑平整,厚度应均匀,最小厚度为0.4毫米.线对：可分为以下4种护套：聚氯乙烯护套材料的性能要求应符合GB8815的规定,平行室内线护套的横截面挤成扁圆形,绞合室内线的护套横截面挤成圆形.护套应完整连续,无缺陷表面光滑平整,。
另外，校准5502A的电阻功能时，**根据测试点数值使用8508A电阻测量功能的手动量程，避免设置在自动量程时，测量仪表在寻找合适量程的同时，校准器也在寻找合适的工作电流，使得两台仪器不能尽快选择到合适的量程和合适的电流范围，而不能正常测量，长时间得不到正确的测量结果。在校准5520A和5522A电阻功能时，在36MΩ，110MΩ两个校准测试点，不确定度为1.7和2.7。不能满足校准要求。可以应用校准边界保证(Guardbanding)，在校准调整时，更严格地控制校准器的偏移，来满足校准的要求。

The shielding layer can not only restrain the electromagnetic wave from transmitting, but also act as a channel for short-circuit current, which can protect the neutral core. 6/10 kv dedicated cable frequency conversion motor, considering the cables, external force is often in the process of using radial outside the cable shielding layer increased galvanized steel tape armoured layer (between shielding layer and steel tape armoured layer of sleeve).
KFF22，KFP1F，KFP2F22，应不小于电缆外径的12倍。使用条件:电缆使用环境温度为－40℃～+50；在25℃时湿度为95%；电缆敷设温度≥－10℃；电缆敷设时的弯曲半径MHYV≥10倍电缆外径，其余型号≥15倍电缆外径。
敷设时电缆的温度应不低于0℃，敷设时弯曲半径应不小于电缆外径的10倍。有铠装层或铜带屏蔽结构的电缆，应不小于电缆外径的12倍。ZR-KVVRP阻燃聚氯乙烯绝缘，阻燃聚氯乙烯护套铜丝编织屏蔽软控制电缆同上具有防干扰能力。
一个传送带，在传送带的起点有两个按钮：用于起动的S1和用于停止的S2。在传送带的尾端也有两个按钮，用于启动的S3和用于停止的S4。要求能从任一端起动或停止传送带。另外，当传送带上的物件到达末端时，传感器S5使传送带停止。传送带示意图对于端子接线图其实很简单，相信大家都能看懂，如下图端子接线图接线图有了，对应的地址分配也就有了地址分配下面就是写程序很序了，这个程序很简单，相信很多懂电的同学不用PLC直接用继电器就可以控制，欢迎大家评论流图运动控制程序对于这个程序大家应该都能看的懂吧，I1.1和I1.3对应启动按钮，当闭合时Q4.0置位，输出1，电机启动，当I1.2和I1.4闭合时Q4.0复位输出0，电机停止，传感器为常闭，当物件接近时，传感器变常开，I1.5常闭触电接通，电机复位。

Flame-retardant Cables: ibec60332-3 / bs4066-3 flame-retardant grades (BunchedWires or Cables vertical Flame On BunchedWires/Cables) this is a beam cable. According to the test regulations, the 3.5m long cable samples are fixed with iron wire on the trapezoid frame, and the number of samples is determined according to the non-metallic materials required for different classification. The sample is hung vertically on the back wall of the furnace and air is introduced into the furnace through the inlet on the bottom plate. At 750 ℃ flame propane plane and the sample, the sample in the compulsory blowing (5 m3 / min air emissions, wind speed 0.9 m/s), must be in vertical combustion is not up to 20 minutes, cable within 2.5 meters flame spread out on its own. IEC60332 is divided into A, B, C and D to evaluate the flame retardant performance.
