The invention provides a production method of a reinforced dropper and an electrified railway contact network. The production method of the reinforced dropper comprises the following steps: preparing an oxygen-free copper alloy rod; reinforcing the oxygen-free copper alloy rod; cold-rolling or drawing the reinforced oxygen-free copper alloy rod; annealing the cold-rolled or drawn oxygen-free copper alloy rod; carrying out wire drawing on the annealed oxygen-free copper alloy rod to form a single oxygen-free copper alloy wire; stranding a plurality of oxygen-free copper alloy wires to form a wire; antiseptically processing the plurality of oxygen-free copper alloy wires stranded into the wire, and eliminating the stress to obtain the reinforced dropper wire; and assembling the reinforced dropper wire and a dropper accessory to form the reinforced dropper. The invention also provides the electrified railway contact network. The dropper close to a bearing cable locating point adopts the reinforced dropper, and the dropper on other parts adopts the normal-specification dropper. By adopting the electrified railway contact network, the fatigue breaking of the dropper can be effectively prevented.
