Auxiliary device for cable withstand voltage test

The utility model provides an auxiliary device used for a cable withstand voltage test, which comprises a support made of insulating materials with increased height and a belt made of the insulating materials, one end of the support is connected with a base, a turntable is arranged on the upper surface of the base, two fixing frames are oppositely arranged on the upper surface of the turntable, fixing buckles are arranged on the fixing frames in a coupling mode, and the belt is made of the insulating materials. One end of the belt is connected to one fixing buckle, the belt buckle is arranged on the belt, the fixing hook is arranged on the belt buckle, the belt is connected to the other fixing buckle along with the belt buckle through the fixing hook, the belt can be tightened through the belt buckle, the cable is fixed more firmly, and therefore the situation that the cable is fixed unstably can be avoided, and the experiment accuracy is improved. And the problem of insufficient experiment safety distance ca
