　　100对及以上线对的电缆加有1％的预备线对，但多不超过6对。缆芯内的间隙用石油膏填充。5、缆芯包带：用聚脂薄膜带绕包。6、屏蔽：铜丝屏蔽或用轧纹(或不轧纹)金属带，金属带纵包于通信电缆缆芯包带之外。7、护套：蓝色低密度聚乙烯。

　　这种区别是由历史原因造成的，而不是由于技术原因或生产厂家。同轴电缆的这种结构，使它具有高带宽和极好的噪声抑制特性。同轴电缆的带宽取决于电缆长度。1km的电缆可以达到1Gb/s~2Gb/s的数据传输速率。



At present, with the continuous development of kejiping, the flame retardant problem has gone from halogen flame retardant in the past to low halogen and non-halogen flame retardant. Companies in the development and production "of" communication power supply with the antiflaming fire-resistant flexible cable, the cable insulation and sheath using the low smoke zero halogen, high decomposition temperature and good mechanical properties of halogen-free, polymer materials, due to cable contains no halide and metal oxide, in does not produce harmful gases, and a lot of smoke, there is no cause the possibility of "secondary disasters", and it also has good mechanical properties and electrical properties, the operating re of cable, completely changed the deficiency of past flame retardant cable.

1.1FC105功能描述SCALE（FC105）功能将一个整形数INTEGER（IN）转换成上限、下限之间的实际的工程值(LO_LIMandHI_LIM)，结果写到OUT。公式如下：OUT=[((FLOAT(IN)–K1)/(K2–K1))*(HI_LIM–LO_LIM)]+LO_LIM常数K1和K2的值取决于输入值（IN）是双极性BIPOLAR还是单极性UNIPOLAR。双极性BIPOLAR：即输入的整形数为–27648到27648，此时K1=–27648.0，K2=+27648.0单极性UNIPOLAR：即输入的整形数为0到27648，此时K1=0.0，K2=+27648.0如果输入的整形数大于K2，输出(OUT)限位到HI_LIM,并返回错误代码。

到底是家里电路出现问题还是空气开关的问题呢?别着急，今天紫电君给大家聊一下空气开关不断跳闸的5大原因。空气开关电流整定值太低，负荷的功率大于空气开关的额定功率。柜式空调回路和电热水器回路的开关整定值都应为20A，而不是一般回路的16A(大功率的浴霸也是这样)。负载的接头不太牢固，部分通过人工接线的电器，接头没有压紧。线路中有短路现象，检查电器插头是否干燥。线路老化漏电了，造成火线和零线都有电，可以检查漏电保护器，如果跳起，表示电器漏电。
