High-tenacity and low-resistance load-bearable detective cable

The utility model provides the technical scheme of a high-tenacity and low-resistance load-bearable detective cable. The cable adopting the technical scheme comprises three copper stranded wires which are provided with insulation layers and stranded together, an insulation sheath is arranged on the outer side of the stranded copper stranded wires, an inner armor steel wire layer is arranged on the outer side of the insulation sheath, an outer armor steel wire layer is arranged on the outer side of the inner armor steel wire layer, the surfaces of steel wires of the inner armor steel wire layer are coated with anticorrosive layers, and the surfaces of steel wires of the outer armor steel wire layer are also coated with anticorrosive layers. The cable adopting the technical scheme has the advantages of smaller resistance, higher tenacity and corrosion resistance.
