Windage yaw prevention insulator

The utility model relates to a windage yaw prevention insulator. Problems of troublesome processing, high processing cost and easy breaking of an insulating rod of an existing windage yaw prevention insulator are mainly solved. The windage yaw prevention insulator comprises a connecting flange (1), an insulating rod (2), a connecting head (3), rubber umbrella covers (4) and an equalizing ring (5). The connecting flange (1) and the connecting head (3) are respectively provided with a first sleeve (6) and a second sleeve (7). The windage yaw prevention insulator is characterized in that the insulating rod (2) and the first sleeve (6) are in interference fit and the insulating rod (2) and the second sleeve (7) are in interference fit, both the inner walls of the first sleeve (6) and the second sleeve (7) are provided with uniform fine teeth (8). According to the windage yaw prevention insulator, the interference fit connection is employed, and the windage yaw prevention insulator has the advantages of convenient processing, low processing cost and high strength of the insulating rod.
