Shielded cable - Wikipedia
A shielded cable or screened cable is an electrical cable that has a common conductive layer around its conductors for electromagnetic shielding. [1] This shield is usually covered by an outermost layer of the cable.
There are two types of shielding typically used for cables: foil and braid. Foil shielding used a thin layer of aluminum, typically attached to a carrier such as polyester to add strength and ruggedness.
