The invention discloses a simple-root breakage high-altitude connecting method for a 330kVdouble bundled conductor. The high-altitude connecting method is adopted, an operator only needs to use a first electrician carrying pulley and a marline climbing rope ladder to reach an operation position, a conductor clamping device is clamped on a small side breaking head of the conductor, a ground electrician enables the conductor clamping device to be clamped on a big side breaking head of the conductor on the ground, then a conductor card is connected with a twisting mill through a steel wire rope, the twisting mill drags the conductor in a gear to the position parallel to a spacing rod, and the breakage conductor is connected through a first electrician full-tension connecting stripe (FTSMS10008-LGJQ300). Tools and materials are simple and light, convenient to carry, small in working quantity, capable of rapidly repairing and recovering line operation.
