Method for forming a shield connection of a shielded cable with the steps of pushing a sleeve onto a shield of a cable, inserting the cable with the sleeve into a magnetic pulse welding coil, and energizing the magnetic pulse welding coil with a current pulse in such a way that the sleeve is joined to the shield with a material bond.

Electrical cables and processes for making and using same. In some examples, the electrical cable can include one or more insulated electrical conductors and one or more metallic elements cabled together and a metallic layer disposed about the one or more insulated electrical conductors and the one or more metallic elements. The one or more metallic elements can partially fill a space located between the one or more insulated electrical conductors and the metallic layer. The one or more insulated electrical conductors can each include an electrically conductive core, a layer of electrically insulating material disposed about the electrically conductive core, and a layer of metallic strands disposed about the layer of electrically insulating material.
