[0002] The withstand voltage test of power cables is a crucial step in cable quality inspection and an important routine test that plays an indispensable role in factory production. However, when faced with a large number of cables to be tested, conducting withstand voltage tests on each one individually would undoubtedly consume a significant amount of valuable time, posing a substantial challenge to product delivery cycles. For example, testing three reels of five-core power cables individually would require a total of 45 minutes, and this is only the withstand voltage test time; the reversing operation during the process also consumes a considerable amount of time.

[0003] In the existing technology, since there is no series connection device, each cable reel is an individual and needs to undergo a separate withstand voltage test. If each cable reel undergoes a withstand voltage test separately, the test time will double, affecting production efficiency and increasing workload. If the cables are simply connected in series, problems such as unreliable connection, time-consuming and labor-intensive connection, and inconvenient disassembly may occur. Utility Model Content

[0006] As a further improvement of this utility model, the connection between the insulated wire core and the alligator clip is fixed by soldering, and an insulating tape or sleeve is applied to the outside for insulation protection.

[0007] As a further improvement of this utility model, the conductor of the main body of the power cable is made of 189 strands of 0.20mm single wires of Class 6 conductor, the average insulation thickness is 1.0mm, and the thinnest sheath thickness is 1.60mm.
