For lightning protection, it is necessary to regularly measure the grounding resistance of the grounding device. In the test process, the ground resistance test line needs to be used. The existing ground resistance test line is directly entwined. When in use, the ground resistance test line needs to be disassembled, and the wire end should be pulled out to release the line. After use , and directly take back the ground resistance test wires and then wind them together. Before each operation, the ground resistance test wires are all wound together, and it takes a lot of time to unwind the wires. To use it again, it needs to be carefully wound, so that it takes a long time to take in and out the line, at least 20 minutes, which reduces work efficiency, troublesome operation, and extremely inconvenient use.
