住宅小区及工厂使用的电压220V/380V,低压变电所为我们用户提供的供电方式有两种方式：第一个是TN-C供电方式（用的线制是三相四线制），第二种是TN-S供电方式（用的线制是三相五线制）那么我们分别对这两种进行讲解。TN-C供电方式TN-C方式供电系统它是用工作零线兼作接零保护线，可以称作保护中性线，可用PEN表示TN-C供电方式属于三相四线制，这种供电方式中，中性线直接于大地连接。接地线和中性线合二为一。

Propane burner plane with the flame of 750 ℃ and contact sample, sample in the compulsory blowing (5 m3 / min air emissions, wind speed 0.9 m/s), must be in vertical flame combustion is not up to 20 minutes, cable within 2.5 meters flame spread out on his own. IEC60332 is divided into A, B, C and D to evaluate the flame retardant performance.

Armoured oil filled telecommunication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of cable, in order to increase the mechanical strength of the cable, improve the ability of anti erosion, is vulnerable to mechanical damage and vulnerable to erosion area of telephone cable designed. It can be laid in any way, more suitable for direct burial in rock areas.

一定条件下，我们可以在输入端做出“人为动作”，来迫使输出端作出相应的反应。其实任何器件，都不难找到相应的检修和判断方法，器件的正常工作与否即使如雪泥鸿爪，也总会“有迹可寻”。为此，需要研究触发器的输入电路形式，并据此采用相应的“人为动作”，而不会导致在线器件（如触发器的前级电路）的损坏。对器件检测的方法，是上电检测输入、输出状态得出结论，远比测量引脚电阻、摘下后放入IC测试仪进行检测，更为方便和准确。

　　填充材料填充式电缆应在缆芯的间隙及缆芯与包带的间隙均匀而连续地填满符合规定的填充复合物。缆芯包带缆芯包带用具有足够的隔热性能和机械强度的绝缘带重叠绕包。以防导体绝缘在加屏幕和挤出挤套过程中粘接、变形和损伤。
