　　当用于直流系统时，该系统的标称电压应不大于电缆额定电压的1．5倍。注：系统的工作电压允许长时间地超过该系统标称电压的10%。如果电缆的额定电压至少等于该系统的标称电压，则电缆可在高于额定电压10%的工作电压下使用。



　　无卤低烟阻燃电缆的特点是不仅拥有良好的阻燃性能，而且构成低烟无卤电缆材料的不含卤素，燃烧时的腐蚀性和毒性较低，产生极少量的烟雾，从而减少了对人身、仪器、设备的损害，有利于发生火灾时及时救援，虽然有良好阻燃性、耐腐独性、极少烟雾浓度等，但其在机械性及电气性能比普通电缆稍差。

HB型混合式步进电机结构为两个导磁圆盘中间夹着一个永磁圆柱体轴向串在一起，两个导磁圆盘的外圆齿节距相同，与前述的VR型可变磁阻反应式步进电机转子结构相同，其两个圆盘的齿错开1/2齿距安装，转子圆柱永磁体轴向充磁一端为N极，另一端为S极。此种电机转子与前面叙述的PM型永磁步进电机转子从结构来看，PM型转子N极与S极分布于转子外表面，要提高分辨率，就要提高极对数，通常20mm的直径，转子可配置24极，如再增加极数，会增大漏磁通，降低电磁转矩；而HB型转子N极与S极分布在两个不同的软磁圆盘上，因此可以增加转子极数，从而提高分辨率，20mm的直径可配置100个极，并且磁极磁化为轴向，N极与S极在装配后两极磁化，所以充磁简单。

　　目前，常用的有两类：50Ω和75Ω的射频同轴电缆。特性阻抗75Ω射频同轴电缆常用于，故称为CATV电缆，传输带宽可达1GHz，目前常用CATV电缆的传输带宽为750MHz。（2）对称射频电缆对称射频电缆回路其电磁场是开放型的，由于在高频下有辐射电磁能，因而使衰减增大，并导致屏蔽性能差，再加上大气条件的影响，通常较少采用。

两端接地屏蔽效果更好，但信号失真会增大。请注意：两层屏蔽应是相互绝缘隔离型屏蔽。如没有彼此绝缘仍应视为单层屏蔽。外层屏蔽两端接地是由于引入的电位差而感应出电流，因此产生降低源磁场强度的磁通，从而基本上抵消掉没有外屏蔽层时所感应的电压；而内层屏蔽一端接地，由于没有电位差，仅用于一般防静电感应。下面的规范就是佐证：《GB50217-1994电力工程电缆设计规范》——3.6.8控制电缆金属屏蔽的接地方式，应符合下列规定：计算机监控系统的模拟信号回路控制电缆屏蔽层，不得构成两点或多点接地，宜用集中式一点接地。
