Purpose: this product USES high pressure polyinsulation with small interface constant.

使输出的直流更平滑。去耦电容相当于电池,避免由于电流的突变而使电压下降,相当于滤纹波。在电子电路中,去耦电容和旁路电容都是起到抗干扰的作用,电容所处的位置不同,称呼就不一样了。对于同一个电路来说,旁路电容是把输入信号中的高频噪声作为滤除对象,把前级携带的高频杂波滤除,而去耦电容也称退耦电容,是把输出信号的干扰作为滤除对象。从电路来说,总是存在驱动的源和被驱动的负载。如果负载电容比较大,驱动电路要把电容充电、放电,才能完成信号的跳变,在上升沿比较陡峭的时候,电流比较大,这样驱动的电流就会吸收很大的电源电流,由于电路中的电感,电阻(特别是芯片管脚上的电感,会产生反弹),这种电流相对于正常情况来说实际上就是一种噪声,会影响前级的正常工作。

  2.绝缘电气强度:导体之间1min1kv不击穿导体与屏蔽1min3kv不击穿3.绝缘电阻:每根芯线与其余线芯接地,控制电缆大于10000MΩ.km,HYAT电缆大于3000MΩ.km。4.工作电容:平均值52±2nF/km5.远端串音防卫度:150kHZ时指定组合的功率平均值大于69dB/km。

The cross section of the control cable is generally no more than 10 square meters, and the power cable is mainly used to transport power, which is generally large. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section of the general factory is relatively less, you can do and control cable section generally small, generally not more than 10 square, tell from some cable, power cable according to the demand of power grid more generally for 5 core, and control cable transmission control, some more, according to the terms of more than 61 core, but also can produce according to user requirements.

  主要用於管道敷设。在缆芯中和屏蔽层的内外表面用石油膏填充和浇注处理,以防止水分侵入。在一30~C一60~C的环境条件下,电缆的机械和电气性能保持不变。结构:导线:退火裸铜线,铜线直径为0.32,0.40,0.50,0.60,0.70,0.80,0.90(mm)。

两种方法下载程序1:采用RS-232C的com端口2:USB口来下载,plc上有两个接口,一个是圆形的九针口,一个是miniUSB口,如下图所示:黄线插圆形口,蓝线插小方形口。程序编好后,如果采用RS232com口使用黄颜色线,在PLC软件中,在导航中双击连接目标:在左上角的计算机侧I/F一排的SerialUSB,双击它:选择第一个RS232C,选择好com口,如果不清楚是哪个com口,打开电脑设备管理器找到端口(COM和LPT)就出出现连接的com口选择完后确认点击通信测试:连接成功,点击确定。

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.
