　　一般信号电缆传输的信号很小，为了避免信号受到干扰，信号电缆外面有一层屏蔽层，包裹的导体的屏蔽层，一般为导电布，编织铜网或铜泊（铝），屏蔽层需要接地，外来的干扰信号可被该层导入大地，避免干扰信号进入内层导体干扰同时降低传输信号的损耗。

For example, zr-djypv zr-djypvp et al. (2) armored (steel belt armored) cables need to add code "22" in the lower right corner of the model, such as: DJYPV22 djypvpppvp22, etc. The cable is mainly used for ac or dc 300V or below and can work normally when 500V or below.



　　电缆型号中的代号及含义GH高速公路通信电缆省略铜Y实心聚烯烃绝缘A铝塑粘接综合护层T填充式按GB2952.1及GB2952.3的规定主要规格规格(线径mm).2四线组数3注:根据用户要求可以设计和生产其它规格和多个四线组.产品技术要求导体导体采用符合规定的TR型软圆铜线。

它在测量直流电流的时候，也是根据不同的档位，并联了不同电阻值的电阻，这样在并联电阻的两端的电压降，必须满足满量程的指示，又不至于万用表表头过流。测量直流电流时，通过并联电阻分流，根据分流后的指示电流计算得到的电流值。它在测量被测电阻器的电阻值时候是根据全。电路欧姆定律的公式。这样就要求万用表内部附加一只1.5v干电池和一块9v的高压叠层池。而1.5v的干电池，主要用于欧姆档1Ω~1kΩ的低阻测量，而9v叠层电池主要用于万用表的高阻档10K、100K档位来测量兆欧级（MΩ）电阻器的电阻值的测量。

：裸导线和塑料绝缘线的高温度一般不超过70℃；橡胶绝缘线的高温度不得超过65℃；变压器的上层油温不得超过85℃；电力电容器外壳温度不得超过65℃等。这就是说电气设备正常的发热是允许的。但当电气设备的正常运行遭到破坏时，发热量增加，温度升高，在一定条件下，可能引起火灾。引起电气设备过热的不正常运行大体包括以下几种情况：短路：发生短路时，线路中的电流增加为正常时的几倍甚至几十倍，而产生的热量又和电流的平方成正比，使得温度急剧上升，大大超过允许范围。
