Self-supporting full-plastic cable (HYAC) : self-supporting full-plastic cable has two kinds of concentric structure and calabash structure. The commonly used HYAC full-plastic cable is calabash structure. Wire: annealed bare copper wire with diameter of, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9; Color the insulation line according to the full chromatographic standard. A single insulated wire is twisted in pairs at different pitch to minimize crosstalk and a specified chromatographic combination is used to identify pairs of wires. Cable core: the cable core structure is based on 25 pairs of cables. More than 25 pairs of cables are assembled according to the unit. Each unit is wrapped with the unit of specified chromatogram to identify different units. More than 100 pairs of cables plus 1% of the reserve pair. Shielding: the shielding layer is made of corrugated metal tape which is wrapped vertically on the outside of the cable core wrap belt and firmly bonded on both sides. The metal strip of the shielding layer is coated with plastic film to facilitate bonding with the sheath to prevent corrosion of the shielding layer. Protective sleeve: protective sleeve is black low density polyethylene, can use double protective sleeve according to the need.

一般现在的家庭装修要求都是空调另外一组线，且必须是4平方以上的铜芯线，可同时开几台家用空调。大伙觉得是这样吗？老师傅说，因为空调是大功率电器，所以一般情况下空调肯定是要单独布线走线的。空凋这种大功率电器在启动时产生的电流比较大，很容易对其他电器产生频繁的冲击，这就要求空调的电源线一定要单独走线。空调是一个家庭的用电大器件，不是指它的功率大，而是它的运作时间长。而且每家选择的空调样式也不一样，有的家庭喜欢用挂机，而有的喜欢用柜式的。

上图表示两相步进电机的结构（PM型）及其运行原理，从图到图顺时针旋转90°，依次图、均旋转90°，依次不断运转成为连续旋转。以上图为例，假如A相有两个线圈，单向电流交替流过两个线圈，也可产生相反的磁通方向，此方式称为单极（uni-plar)型线圈。如下图所示线圈内部只流过单方向电流，此线圈称为单极型线圈；另一种，线圈内流过正、反方向电流的线圈称为双极型线圈，两种线圈的优缺点将在后面的课程中详细介绍。
