Abstract (en)

An electrical cable (10) with a core (20) and a shield (30) surrounding the core (20) is disclosed. The shield (30) is made up of a first shielding layer (40) surrounding the core (20) which is made of conductive metal wire, a first conducting layer (50) surrounding the first shielding layer (40) which is made of semi-conducting expanded polytetrafluoroethylene (ePTFE), a second shielding layer (60) surrounding the first conducting layer (50) which is made of a metallised fabric, a second conducting layer (70) surrounding the second shielding layer (60) which is also made of semi-conducting ePTFE, and a third shielding layer (80) surrounding the second conducting layer (70) which is also made of conductive metal wire. The semi-conducting ePTFE is made in the disclosed embodiment of graphite-filled ePTFE and the metallised fabric of copper-coated polyamide fabric. The electrical cable (10) of the invention has a flex-life of at least 1.2 million cycles and a shielding effectiveness of more than 80 dB at 1 GHz. <IMAGE>
