Research on Field-circuit Co-simulation of Cable Shielded with Pigtail

A semi-exposed cable model is proposed and analyzed with field-circuit co-simulation in this paper. In this model, the braided shields of these semi-exposed cables are grounded with pigtail to decrease the electromagnetic leakage and crosstalk on the surrounding cables caused by the exposed parts. The semi-bare cables are modeled and analyzed efficiently with the CST cable studio. The effectiveness of our proposed model is determined by comparing the simulation results of different circuit connections, those are semi-bare cable loaded with pigtail and not. The results show that the pigtail can not only reduce the interference of external electromagnetic field to cable, but also can reduce the crosstalk between cables.
