Definitions

  • the present application discloses a multi-core direct-current submarine cable, including a structure in which two identical polar electric units and an additional electric unit assembly are integrated into a cable and are fully armored.
  • An outer diameter of the cross-section of the additional electric unit assembly is the same as an outer diameter of the cross-section of each polar electric unit.
  • Filling strips are arranged between the internal polar electric unit and the additional electric unit assembly, so as to reduce the material cost and the laying cost, and give roundness to the cabling of cores with different size.
  • the additional electric unit assembly includes an additional electric unit and at least one additional filling strip arranged at a side of the additional electric unit.
  • a multi-core direct-current submarine cable of the present application includes two identical polar electric units 11 and 12, an additional electric unit assembly 13, several optical units 14, several filling strips 15, a belt 161, a cushion layer 162, an armored layer 163, and an outer protective layer 164.
  • An outer diameter of the cross-section of the additional electric unit assembly 13 is the same as outer diameter of the cross-sections of the polar electric units 11 and 12 to improve roundness after cabling.
  • the two polar electric units 11 and 12 are twisted together with the additional electric unit assembly 13, and are sequentially provided with the belt 161, the cushion layer 162, the armored layer 163, and the outer protective layer 164 wrapped around same.
  • Several optical units 14 are arranged in gaps between the two polar electric units 11 and 12, the additional electric unit assembly 13, and the belt 161, and several filling strips 15 are arranged in gaps between the two polar electric units 11 and 12, the additional electric unit assembly 13, and the belt 161.
  • the stranding equipment of the multi-core direct-current submarine cable is shown in FIG. 9 , which includes three additional electric unit turntables 30A.
  • the three additional electric unit turntables 30A need to first rotate counterclockwise around the stranding center 302A to complete a primary stranding.
  • each additional electric unit 131C rotates clockwise to eliminate axial torsion of the cable itself.
  • the twisted additional electric unit 131C and the two polar electric units 11 and 12 rotate counterclockwise around the central shaft 20 to complete a secondary stranding.
  • Other working processes of the third variant are the same as the original scheme.
