Flame-retardant cable classification: according to the different flame-retardant materials of cables, flame-retardant cables are divided into halogen flame-retardant cables and halogen-free low-smoke flame-retardant cables. Which contain halogen flame retardant cable insulation, sheath, outer sheath and auxiliary material (package belt and filling) in whole or in part by polyethylene (PVC) containing halogen flame retardant material, thus has good flame retardant properties. However, when the cable burns, a large amount of smoke and haloic acid gas will be released. Haloic acid gas is corrosive to the surrounding electrical e When the cable burns, it will cause harm to the surrounding electrical e and rescue personnel, which is not conducive to the fire fighting and rescue work, thus causing serious "secondary hazards". All or part of the insulation layer, protective sleeve, outer protective layer and auxiliary materials (packing belt and filling) of the halogen-free low-smoke flame-retardant cable are adopted

　　同轴电缆是专门设计用来传输视频信号的，其频率损失、图像失真、图像衰减的幅度都比较小，能很好的完成传送视频信号的任务。¬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。

为了评估步进电机的特性，必须要有必要的测量方法，从本节开始首先讲解下步进电机的静态转矩特性及步进角精度。静态转矩特性静态转矩特性为步进电机的转子静止状态（平衡状态）的特性，该特性与时间无关，静态转矩特性也称为角度-静态特性或刚度特性，是步进电机定子直流激磁状态下，负载转矩与转子位移角度的变化关系。此转矩如右图所示，以正弦规律变化，大转矩为，产生的静态转矩T与位移角θ的关系如下：其中，图中的θ、θL、θM为机械角度。

主厂房DCS的竞争往往在不同品牌的供应商或代理商之间展开，竞争激烈，DCS的价格不断下调。而辅助车间控制系统的竞争往往在同一品牌PLC的各个工程商之间进行，门槛较低，竞争更加激烈，但是PLC的价格下调幅度却并不如DCS明显。主要原因是DCS的生产商直接参与竞争，在巨大的市场压力下，不断下调设备制造费用和工程实施费用。而PLC的生产商不直接参与竞争，各个工程商只能下调自身有限的工程费用，空间有限。从现在情况看来，DCS与高档PLC的价格差距已不明显，辅助车间仍然较多地采用PLC，是市场的惯性使然。

Because of the refractory layer of the refractory cable, the multi-layer mica belt is usually used to wrap directly around the wire. It can withstand long periods of time, even if the polymer at the point where the flame is applied is burned down, it can keep the line running.
