Vertical production line of cable for new energy electric vehicle

Disclosed is a vertical production line of cables for new energy electric vehicles. The vertical production line comprises a pay-off reel, a first traction machine, an extruder, a vulcanizing device,a second traction machine and a take-up reel which are installed in sequence, the vulcanizing device comprises an ascending vulcanizing section, a descending vulcanizing section and a reversing wheel,the ascending vulcanizing section and the descending vulcanizing section each comprise at least two vulcanizing pipes, each vulcanization pipe further comprises two vulcanization pipe units, and a preheater is installed between the ascending vulcanizing section and the extruder. According to the invention, the vulcanizing device is divided into the vertically arranged ascending vulcanizing section and descending vulcanizing section, so that rubber on a conductor does not generate an eccentric effect on the conductor under the action of gravity, the ascending vulcanizing section or descendingvulcanizing section is divi
