WDT-1 Wire Strength Damaged Tester utilizes a guide rail and lead screw structural design. The test count can be preset, and the device will automatically cease operation and emit an audible alert upon completion of the predetermined test count. This apparatus is employed to evaluate the endurance of threaded and unthreaded terminals against mechanical stress during standard operational conditions, thereby determining if the terminal’s design and construction comply with the requisite standards to prevent excessive wire damage during clamping.
