Study on Signal Attenuation Performance of Mineral Insulated Coaxial Armored Cable

对常用的矿物绝缘同轴铠装电缆在标准信号及实测脉冲信号条件下进行信号衰减特性研究,研究结果表明,采用氧化硅绝缘的同轴铠装电缆信号衰减性能最优,同时芯线电阻越小,电容越小,对信号传输越有利,结合这三种特性,可以获得更好的测试性能。

This article studies the signal attenuation characteristics of commonly used mineral insulated coaxial armored cables under standard signal and measured pulse signal conditions.The research results indicate that the coaxial armored cable with silicon oxide insulation has the best signal attenuation performance,and the smaller the core resistance and capacitance,the more favorable for signal transmission.Combining these three characteristics can achieve better testing performance.
