Insulated wire connecting method for setting up middle and low voltage overhead power line

The invention relates to an insulated wire connecting method for setting up a middle and low voltage overhead power line, and belongs to the technical field of middle and low voltage overhead power lines. The technical scheme is that the outer insulating layers of insulated wires are added with pigments in three colors of yellow, green, and red, and the outer insulating layers of produced insulated wires are in three colors of yellow, green, and red, according to a phase sequence that the three colors of yellow, green, and red of the outer insulating layers of insulated wires are respectively corresponding to three phases of A, B, and C, laying the insulated wires (4) in sequence on a concrete rod (3); when an insulated wire connecting point a (5) and an insulated wire connecting point b (6) in the same color occur, connecting the insulated wires in the same color, so as to complete connection of insulated wires and prevent wrong connection of phase sequence. Beneficial effects of the method are that on the premise that electrical properties of insulation and strength of insulated wires are not affected, the method can rapidly distinguish phase sequence, provides convenience for connection, and the wires would not be connected in a wrong way, and in circuit patrol, the method can rapidly find out fault points.
