The utility model provides a cable buffer layer volume resistivity measurement device, an evaluation method and a system. The device comprises: a first electrode; a second electrode, wherein the second electrode is arranged above the first electrode; the tray is arranged above the second electrode; the counterweight piece is arranged on the tray; two ends of the power supply module are respectively connected with the first electrode and the second electrode; and the test module is connected with the test loop. According to the utility model, the actual condition of the buffer layer in the corrugated aluminum sheath high-voltage cable is fully considered, and the second electrode matched with the actual contact point area between the buffer layer and the corrugated aluminum sheath is selected according to the measurement problem of the buffer layer, so that the improvement of the shape of the second electrode is closer to the real contact surface between the buffer layer and the metal sheath; the tray and the
