Flexible cable

The present invention relates to a traveling cable which can prevent the separation of the sheath and bedding of the traveling cable even in an environment where the traveling cable is twisted or a tensile force is applied to the traveling cable, and can maximally withstand the tensile force due to twisting. The traveling cable includes a plurality of power line units composed of conductors and insulating layers, a plurality of ground line units which are arranged between the adjacent power line units, a signal line unit composed of a plurality of signal lines, a bedding layer surrounding the power line unit, the ground line unit and the signal line unit, a sheath layer surrounding the bedding layer, and a fiber braiding layer arranged between the bedding layer and the sheath layer. 본 발명은 이동용 케이블이 비틀리거나 이동용 케이블에 인장력이 가해지는 환경에서도 이동용 케이블의 시스와 베딩이 분리되는 것을 방지하고 비틀림에 따른 인장력을 최대한 견딜 수 있는 이동용 케이블에 관한 것이다.
