The phase-separated inner sheath fastens the wire core to prevent displacement when moving, and the phase-separated outer sheath protects the wire core from external mechanical stress for normal operation.

Preferably, a phase-separated shielding layer is provided between the phase-separated inner sheath and the phase-separated outer sheath.

Preferably, the overall sheath includes an inner sheath and an outer sheath extruded outside the inner sheath. The inner sheath fastens the twisted group to prevent displacement during movement, and the outer sheath protects the wire core and the twisted group from external mechanical stress for normal operation.
