Why do you want to pack a layer of aluminum foil when you make a wire?
Cable foil requires surface with less oil, no holes, with high mechanical properties, the overall quality requirements are not high, but the length requirements are extremely strict.
Generally used as a signal line of the wire aluminum foil is shielding effect, used to reduce the external signal-free signal on the transmission of interference, if only conductive, no need to use aluminum foil.
Single or double coated with plastic film, the composition of the aluminum # plastic composite foil, used as a cable shield.
Outside insulation is done for protection or leakage. Cable foil is the use of aluminum foil sealing and shielding
