三极管,全称半导体三极管,也称双极型晶体管、晶体三极管,是一种控制电流的半导体器件其作用是把微弱信号放大成幅度值较大的电信号,也用作无触点开关。
三极管,是半导体基本元器件之一,具有电流放大作用,是电子电路的核心元件。
三极管是在一块半导体基片上制作两个相距很近的PN结,两个PN结把整块半导体分成三部分,中间部分是基区,两侧部分是发射区和集电区,排列方式有PNP和NPN两种。
发射区和基区之间的PN结叫发射结,集电区和基区之间的PN结叫集电结。

本公司生产的耐火型动力电缆为额定电压0.6/1KV铜芯电缆,还可以生产低烟无卤耐火动力电缆、高阻燃隔氧层耐火动力电缆,其耐火性能符合GB/T12666.6《电线电缆耐火特性试验方法》。
耐火系列动力电缆的整体性能优良可靠。
主要用于电缆有长期稳定的负荷,经济技术比较合理,可以用经济电流密度法来选择电缆的截面。
一般按照经济电流密度法选择出来的电缆截面比用允许温升选择出来的电缆截面大1到2级。
对于一些长期不用的回路,不宜按照经济电流密度选择截面。
如何用经济电流密度法来选择电力电缆的截面按照经济电流密度法计算电力电缆截面的公式为Aec=Ic/Jec式中,Aec为导体经济截面(mm2)Ic为线路的计算电流(A),Jec为经济电流密度(A/mm2)。
