Rotation-endurable swinging test ultrahigh-shielding-performance coaxial cable

The utility model relates to a rotation-endurable swinging test ultrahigh-shielding-performance coaxial cable, and aims to provide the cable with advantages of being capable of improving shielding attenuation before and after the swing of the cable, substantially improving static shielding performance of the cable and being simple in structure. The technical scheme is that the rotation-endurable swinging test ultrahigh-shielding-performance coaxial cable comprises an inner conductor, an insulating layer, an outer conductor layer and an outer sleeve, wherein the insulating layer, the outer conductor layer and the outer sleeve coaxially coat the inner conductor from inside to outside in sequence, and the outer conductor layer comprises a three-adhering structure aluminum foil shielding layer, a braided shielding layer and a non-adhering double-sided aluminum foil layer which coaxially coat the insulating layer from inside to outside in sequence. The rotation-endurable swinging test ultrahigh-shielding-performance coaxial cable is characterized in that a wear-resistant insulating buffer strip coats between the braided shielding layer and the non-adhering double-sided aluminum foil layer.
