对称通信电缆工作电容及缆芯外径的计算

Calculation of the mutual capacitance and conductor assembly outer diameter of symmetrical communication cables

利用计算机对塑料绝缘多芯对称通信电缆工作电容与缆芯外径关系进行数值分析后 ,发现引入缆芯外径系数不仅能计算缆芯外径 ,而且还能较精确地计算工作电容。

In the PC-aided numerical analysis of the relationship between the mutual capacitance and conductor assembly outer diameter of multi-core plastic insulated symmetrical communication cables, we found that the introduction of the factor of conductor assembly outer diameter made it possible not only to calculate the conductor assembly outer diameter but to calculate the mutual capacitance with reasonable accuracy as well.
