Grounding clamp for multi-core cable withstand voltage test

The utility model discloses a grounding clamp for a multi-core cable withstand voltage test. The grounding clamp for the multi-core cable withstand voltage test is characterized in that the grounding clamp for the multi-core cable withstand voltage test comprises a black separation clamp, a green separation clamp and a yellow separation clamp, the black separation clamp is connected with a metal shielding layer of a multi-core cable and is connected with a ground wire connecting point through an electric wire, the green separation clamp is connected with a conductor of a core which does not undergo the withstand voltage test, and is connected with the ground wire connecting point through an electric wire, and the yellow separation clamp is connected with conductors of cores which are qualified in the withstand voltage test, and is connected with the ground wire connecting point through an electric wire. The grounding clamp for the multi-core cable withstand voltage test has the advantage that using the ground
