摘要
为了证明电缆结构对电缆的EMC性能有影响,对比了总包屏蔽和总包加分包屏蔽两种结构的仪表控制电缆的EMC性能,分别进行了转移阻抗、屏蔽衰减和串音三项性能的测试。从测试结果可以看出,总包加分包结构的屏蔽电缆的EMC性能要明显优于总包屏蔽电缆。
In order to prove the structure of wires has significant influence, we compared total winding shielded cable with total winding plus respective winding shielded cable in EMC, which included transfer impedance test, screening attenuation test and crosstalk test. According to the results analysis, the EMC of total winding plus respective winding shielded cable is better.
