Abstract
The invention discloses a control cable for ships. The position among a plurality of control conductors and a first flame retardant wrapping tape wrapping layer is filled with high temperature resistant filler; the control conductors are arranged in the high temperature resistant filler annularly; a plurality of insulation boards are arranged in the high temperature resistant filler and surround the control conductors to form heat dissipation spaces with outward openings; the positions, at the two ends of the opening of each insulation board, of the high temperature resistant filler are respectively provided with an axial through hole penetrating through the control cable; the through holes are formed in the inner side of the corresponding insulation boards; the through holes are filled with filler of which the cross section is in a polygon shape. The control conductors are spaced through the insulation boards, so that the control conductors are prevented from concentrated heat dissipation, and heat is prevented from being accumulated in the center of a cable core; once the cable core catches fire, the flame retardant property of the flame retardant wrapping tape is improved through a flame retardant coating, and the time of flame to spread towards an outer sheath layer is prolonged.
