The flame retardant control cable passed iec332-3 wire and cable bunching test, in which the ZRC cable passed iec332-3c bunching test (class C should make the total volume of combustible materials 1.5L/M and the flame time 20min). The ZRA cable passed the iec332-3a beam forming test (the total volume of combustible materials should be 7L/M, and the flame time should be 40min). Class A flame retardant performance is superior to class C flame retardant performance.

　　2.2 电缆型式由系列代号、绝缘、护套材料代号、外护层和性能特征代号5个部分组成。
产品执行GB国家标准。
其中屏蔽型控制电缆，由于具有良好的评比性能得到电厂、电站的大量使用，电缆意义敷设在市内、电缆沟、管道、直埋、竖井等能承受较大机械拉里的固定场合。


相步距角0.9°（定子主极数16）的步进电机转速约150rpm以上，其减少振动量的效果就不明显。
如输入脉冲频率太快，对细分步进波形来说，由于不能得到希望的电流波形，会使电机跟踪精度变差。
第细分步进的细分数与降低振动效果:理论上细分数越多，降低振动的效果越明显，但实际到8细分时效果变化并不大。
8细分与16细分以上不会有效果的差别（即没有什么效果变化）。
下图表示两相HB型16主极的0.9°步进电机细分数与速度波动的图像；下图表示改变细分数与转子速度变化情况，电机同样为两相HB型16主极的0.9°步进电机。


　　适用范围:适用于高速公路中紧急电话通信系统用于传输音频信号及控制信号。
绝缘1绝缘应采用符合规定的高密度聚乙烯。
2绝缘线芯采用颜色识别标志,绝缘颜色识别应均匀,并采用下列颜色:星绞:白、蓝、红、绿单元线组星绞组绝缘线芯按白、蓝、红、绿顺时针排列。
