还可以使用更长的电缆，但是传输率要降低或使用中间放大器。目前，同轴电缆大量被光纤取代，但仍广泛应用于有线和无线电视和某些局域网。射频同轴电缆是指有两个同心导体，而导体和屏蔽层又共用同一轴心的电缆。目前，常用的射频同轴电缆有两类：50Ω和75Ω的射频同轴电缆。
At present, with the continuous development of kejiping, the flame retardant problem has gone from halogen flame retardant in the past to low halogen and non-halogen flame retardant. Companies in the development and production "of" communication power supply with the antiflaming fire-resistant flexible cable, the cable insulation and sheath using the low smoke zero halogen, high decomposition temperature and good mechanical properties of halogen-free, polymer materials, due to cable contains no halide and metal oxide, in does not produce harmful gases, and a lot of smoke, there is no cause the possibility of "secondary disasters", and it also has good mechanical properties and electrical properties, the operating re of cable, completely changed the deficiency of past flame retardant cable.
而且电缆的抗干扰性能高、电气性能稳定。保证了传输信号参数的准确性和控制系统的安全运行。阻燃变频电缆产品用途阻燃变频电缆主要用于变频电源和变频电机之间,连接用的电缆,以及额定电压1KV及以下的,输配电线路中,作输送电能用.尤其适用于造纸、冶金、金属加工、矿山、铁路和食品加工等行业。
如果导轨较轻，则使用人力进行提升就可以了。轿厢安装第一步为安装底部的横梁，首先将横梁放在敷设好的工字钢上，用安全钳等固定好，接着开始安装立柱和上梁，联接立柱和底梁，使立柱处于垂直的状况，再将上梁与立柱联接起来，安装螺栓固定，调整好水平及垂直的角度，用螺栓固定。下一步则是将轿厢的底盘用倒链吊起，用螺丝将其与立柱和底梁联接，调整好位置，最后，对于轿门、轿顶等的安装则只需参照图纸或者相关的条文即可。电气设备安装首先要选择远离门窗的地方安装电气设备的控制柜，用螺丝将其与底座连接，然后在井道内设置中间接线盒和随缆架，安装的高度计算方法是：电梯行程×1/2，加上1700mm，最后是要在坑底装上检修盒，位置应该放在距离线槽较近一侧的地坎下，将其固定于井壁，要注意的是，在接线盒的安装上要注意不能碰厅门的地坎和轨道支架，所有电气设备需有良好的接地。

Fire - resistant cable refers to the cable which can keep safe operation for a certain period of time under the condition of flame burning. China's national standard GB12666.6 IEC331 (e) will fire test points A, B two levels, A grade flame temperature of 950 ~ 1000 ℃, the duration for fire, 90 min, class B flame temperature of 750 ~ 800 ℃, for fire duration 90 min, during the whole test, the sample should be under the rated voltage value of the product. Fire-resistant cable is widely used in high-rise buildings, subway, underground street, large power stations and the important industrial and mining enterprises and other related to fire security and its lifesaving, for example, fire fighting e and emergency light guide emergency facilities such as power supply circuit and control circuit.

具有以下几点特点：1、产品能有效预防白蚁、鼠类对电缆的危害，性能可靠长久，无需其他辅助方法；2、电缆产品内无防蚁鼠电力电缆一、产品特点及用途本产品适用于在蚁鼠危害比较严重，且有绿色环保要求的场所，特别是埋地和管道敷设的电力系统输配线路。
原理：对一段波形中的每N个点求平均，把原来的N个采样点替换成一个平均点来显示。具体原理图如所示。?适用场景：通常用于数字转换器的采样率高于采集存储器的存速率的情形，即可提供较较高分辨率、较低带宽的波形。?注意事项：“平均”和“高分辨率”模式使用的平均方式不一样，前者为“波形平均”，后者为“点平均”。图4高分辨率捕获模式原理图对这4种捕获模式的捕获机制与应用特点了解之后，我们来看下它们对同一个输入信号的显示情况。
