Abstract: The present invention provides an energy-saving and heat-dissipating power line manufacturing method, and relates to the technical field of line manufacturing, and the specific solution is as follows: two feeding mechanisms are arranged on a feeding table in parallel, and one end of a power line wound on the feeding mechanisms penetrates through a cut-off mechanism through a feeding wheel and is fed into a terminal machine; the cut-off mechanism is started through a handle and cuts off the power line; the two feeding mechanisms are driven by a motor to rotate at the same time, and the winding directions of power lines on the two feeding mechanisms are the same. According to the auxiliary device, the problem that an existing line manufacturing terminal machine is low in working efficiency is solved, and synchronous feeding can be achieved by driving the two feeding bases through one motor.
