The utility model discloses a cable with multicore structure, which comprises an inner core, wherein, an inside liner, a steel strip and a PVC polyvinyl chloride sheath are sleeved in sequence outside the inner core, the inner core comprises three large conductors arranged in the shape of a triangle, three small conductors respectively clung to the three large conductors are further arranged in the clearances between the inner wall of the inside liner and the large conductors, and the large and the small conductors are respectively covered with crosslinked polyethylene insulating layers. The utility model is simple in structure and easy to realize. The way that the inner core is formed has the benefits of effectively reducing the resistance of the entire cable, reducing cost, greatly reducing the waste of electric energy during electric power transmission, and improving the efficiency of electric power transmission.
