Bearing type coaxial overhead insulated cable with voltage of 1kV

The invention discloses a bearing type coaxial overhead insulated cable with voltage of 1kV. The cable comprises a steel core bearing wire, a plurality of coaxial conductor layers, a plurality of coaxial insulating layers and an outer protective layer; and the plurality of coaxial insulating layers are respectively arranged on the outer sides of the steel core bearing wire and the plurality of coaxial conductor layers, and the outer protective layer is extruded on the coaxial insulating layer on the outermost side. According to the invention, the coaxial steel core can play a role in discharging current when a cable short-circuit fault occurs, and good safety performance of the cable is guaranteed; the conductors are made of aluminum wires or aluminum alloy wires and are drawn into trapezoidal monofilaments through an aluminum wire drawing machine and a trapezoidal die, then one or more layers of trapezoidal monofilaments are stranded on the insulating layer of the carrier cable, the stranded wire die with th
