　　因此，耐火系列电力电缆的整体性能优良可靠。防火电缆的阻水性能符合IEC502-2规定。电力电缆安装注意事项：电缆与热力管道平行安装时保持2m的距离，交叉时应保持0.5m。电缆与其它管道平行或交叉安装时均要保持0.5m的距离。

两相步进电机简单的构成为Nr=1的情况，电机结构如下图所示。一般两相电机定子磁极数为4的倍数，至少是4。转子为N极与S极各一个的两极转子。定子一般用硅钢片叠压制作，定子磁极数为4极，相当于一相绕组占两个极，A相两个极在空间相差180°，B相两个极在空间也相差180°。电流在一相绕组内正负流动（此种驱动方式称为双极性驱动），A相与B相电流的相位相差90°，两相绕组中矩形波电流交替流过。即两相电机的定子，在Nr=1时，空间相差90°,时间上电流相差90°相位差，电流与普通的同步电机相似，在定子上产生旋转磁场，转子被旋转磁场吸引，随旋转磁场同步旋转。

三相电源中流过每相负载的电流为相电流，用IAIBICA表示。对于星型接法的电动机，相电流等于线电流，对于三角形接法的电动机，线电流等于根号3相电流在星形联接的负载中，流过端线的线电流等于流过负载的相电流，流过中线的中线电流等于各相电流的矢量和。在三角形联接的负载中，相电压等于线电压（各相负载两端的电压仍称为相电压）。一般总是三相负载对称的才接成三角形接法，此时三个线电流对称，三个相电流也对称，线电流等于相电流的“根号3”倍。
