International ClassH01B 007/34Foreign Application Priority Data1999-05-13 JPAbstractA balanced transmission shielded cable includes an inner conductive shield (3) and an outer conductive shield (5) surrounding the inner conductive shield (3). In an annular region (A) defined between both shields (3, 5), unshielded twisted pairs (4) for signal transmission and shielded drain lines (6) are alternately disposed in annular array. The shielded drain lines (6) contact both shields (3, 5) and are led outside and grounded. Both shields (3, 5) surrounding the twisted pairs (4) and the shielded drain lines (6, 6) keep a substantially uniform distance with respect to conductive lines constituting the twisted pairs (4).Other References
