Cable with four cores in asymmetric structure

The utility model discloses a cable with four cores in an asymmetric structure, which comprises an inner core; an inner lining layer, a steel tape and a poly vinyl chloride (PVC) sheath are sequentially sleeved outside the inner core; the inner core comprises three conductors with the cross sections being 90-degree sectors and a conductor with a circular cross section; cross-linked polyethylene (XLPE) insulation layers are respectively and closely coated outside the conductors; and filler is filled between the spacing between the conductors in the inner lining layer. The cable with four cores in the asymmetric structure has simple structure, is easy to realize, effectively reduces the resistance of the whole cable through three conductors with the cross sections being the sectors and the conductor with the circular cross section, has lower cost, greatly reduces the power waste in a power transmission process, and improves the power transmission efficiency.
