电缆的屏蔽要求是根据不同场合分别采用:对绞组合屏蔽、对绞组成电缆的总屏蔽、对绞组合屏蔽后总屏蔽等方法。
屏蔽材料有圆铜线,铜带、铝带/塑料复合带三种。
屏蔽对与屏蔽对具有较好的绝缘性能,电缆在使用中若屏蔽对屏蔽对之间出现电位差时,不会影响信号的传输质量。

交流接触器额定电压交流接触器的额定电压指交流接触器主触点的额定工作电压,应当等于负载的额定工作电压。
交流接触器一般有若干个额定电压值,在技术说明书中会列出相应的额定电流或控制功率。
通常最大工作电压即为额定电压,220-230V,230-240V,380-400V和400-415V等。
额定电流接触器的额定电流指交流接触器主触点的额定电流值。
常用的额定电流等级为9121626304050637595A;110145150175210260A;300375550100013501650A和2000A等。

从趋势上论,无刷电机减速可能取代有刷减速电机适用范围:无刷电机:通常被使用在控制要求比较高,转速比较高的设备上,如航模、精密仪器仪表等对电机转速控制严格,转速达到很高的设备商,现在最为先进的干手器,其电机和控制器的成本都很高,也之后比较高端的设备才被使用。
碳刷电机:通常动力设备使用的都是有刷电机,如吹风机、工厂的电动机、家用的抽油烟机等等,串激电机的转速也能达到很高,由于碳刷的磨损,使用寿命不如无刷电机。

Flame-retardant Cables: ibec60332-3 / bs4066-3 flame-retardant grades (BunchedWires or Cables vertical Flame On BunchedWires/Cables) this is a beam cable. According to the test regulations, the 3.5m long cable samples are fixed with iron wire on the trapezoid frame, and the number of samples is determined according to the non-metallic materials required for different classification. The sample is hung vertically on the back wall of the furnace and air is introduced into the furnace through the inlet on the bottom plate. At 750 ℃ flame propane plane and the sample, the sample in the compulsory blowing (5 m3 / min air emissions, wind speed 0.9 m/s), must be in vertical combustion is not up to 20 minutes, cable within 2.5 meters flame spread out on its own. IEC60332 is divided into A, B, C and D to evaluate the flame retardant performance.
