The invention discloses a power transmission and distribution line insulating rod test rack comprising a test baseplate and an insulating rod body. The left and right sides of the top part of the test baseplate are provided with bushings, and the top parts of the two bushings are sleeved by telescopic rods. The top parts of the two telescopic rods are fixedly connected with the bottom part of a transverse plate. The top part of the test baseplate is provided with a detection groove, and the bottom part of the internal cavity of the detection groove is provided with a current induction contact. The top part of the transverse plate is provided with a through hole which is arranged exactly above the detection groove. The bottom part of the insulating rod body penetrates through the through hole and extends into the detection groove to be contacted with the current induction contact. According to the power transmission and distribution line insulating rod test rack, alarm lamps and buzzers are designed, and the alarm lamps and the buzzers can alarm in time when the disqualified situation of the insulating rod occurs in the detection process so that the work personnel can be prompted to inspect the disqualified situation, the detection efficiency can be enhanced and the labor intensity can be reduced.
