ELECTRIC CABLE
The present disclosure provides an electric cable, comprising two signal conductors, a resin insulating layer, an expanded polytetrafluoroethylene insulating film, an electromagnetic shielding film, two ground conductors, and a covering layer. The resin insulating layer covers the two signal conductors. The expanded polytetrafluoroethylene insulating film covers the resin insulating layer. The electromagnetic shielding film covers the expanded polytetrafluoroethylene insulating film. The two ground conductors are disposed at two sides of the electromagnetic shielding film. The cladding layer dads the electromagnetic shielding film and the two ground conductors. Through the expanded polytetrafluoroethylene insulating film, the electric cable can be applied to compact products, and the electric cable can be highly flexible such that the signal transmission performance would not be affected after being repeatedly bent.
