AI summary

Electrical cables are disclosed can include at least one electrical conductor, an inner electrical insulator that surrounds the at least one electrical conductor, and an electrical shield disposed about the inner electrical insulator. The electrical cables can include an electrically conductive material disposed between adjacent layers of the electrical cable. In one example, an electrical coating can be disposed in the electrical shield, for instance, in regions of overlap. Flowable electrically conductive materials are also disclosed that can flow into gaps during operation of the electrical cable.
