Insulation thickness measuring device for power cable

The utility model belongs to the technical field of thickness measurement, in particular to an insulation thickness measuring device for a power cable, which comprises a bottom plate, a top plate is arranged above the bottom plate, the bottom plate and the top plate are fixedly connected through four connecting rods distributed in a rectangular array, and a movable plate is slidably connected onto the four connecting rods. The lifting mechanism is arranged to control the movable plate to drive the measuring mechanism to move up and down, a larger sample of a cable insulation layer to be measured can be conveniently placed on the bottom plate during measurement, and by arranging the fixing structure, when the movable plate moves downwards, the fixing structure firstly makes contact with the cable insulation layer, so that the bent cable insulation layer is pressed to be unfolded, and then the cable insulation layer is fixed. And through the arrangement of the pressure sensor, when the cable insulation layer is
