Manufacturing method of fan blade pre-embedded lightning arrester downlead cable

A manufacturing method of a fan blade pre-embedded lightning arrester downlead cable comprises the following steps: (1) manufacturing a conductor for later use according to the sectional area specification of the conductor; 2) taking the conductor prepared in the step 1) to carry out shielding layer and insulating layer extrusion to obtain a wire core; and 3) wrapping the cable core prepared in the step 2) with an outer sheath layer. Through a specific process and a corresponding cable material design, the performance of the manufactured down lead cable is improved, and the phenomena of insufficient performance or redundant performance and the like caused by direct use of the existing cable material with similar functions are avoided. The cable manufactured by the manufacturing method meets various performance requirements of the lightning arrester downlead, and also meets the special requirements of mechanical performance, flexibility, salt mist resistance, low temperature resistance and the like under the w
