Power cables have many advantages and occupy less land. Generally, it is buried in soil or laid in indoor, ditch and tunnel. The insulation distance between lines is small. High reliability. It is less affected by climatic conditions and surrounding environment, stable transmission performance and high reliability. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc. The distributed capacitance is large. Less maintenance. It's less likely to shock.

　　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。

　　低烟无卤电线特性：低烟无卤电缆(1)抗张强度比一般PVC电线大：一般PVC电线抗张强度大于1.05Kgf/mm2，而低烟无卤电线抗张强度大于1.2Kgf/mm2；(2)具有良好的耐候性(-30℃~105℃)；(3)具备良好的柔软度(硬度为80—90)；(4)具有非移性(因为此产品配方中不用添加可塑剂。

plc编程不同于计算机软件编程，写好的程序在你电脑上没有任何意义，需要下载带PLC，并结合外部线路和机械设备才能发挥它的价值，这也是自动化技术的特色，必需理论结合实践，必需软硬件结合。今天小编就给大家总结一下，PLC与电脑联机的几种方式。串口串口，是早，也是方便的一种方式，它利用计算机自带的串口和PLC的串口建立连接，早期PLC都是采用这种下载方式。三菱FX系列，西门子S7-200和S7-300系列。
