This invention provides a high-strength insulating rod testing fixture. The insulating rod body to be tested is fixed to a first U-shaped test clamp and a second U-shaped test clamp. An acoustic-optical detector transmits electrical signals from the contact area between the conductive cotton and the insulating rod to the detector via the first and second U-shaped test clamps, thus achieving insulation testing of the insulating rod. Subsequently, the insulating rod body, fixed by the first U-shaped test clamp, is guided by the second U-shaped test clamp to the electrode clamp until the insulating rod body is clamped by both electrode clamps.

After adjusting the clamping position of the electrode clamps on the insulating rod body, one electrode clamp can be grounded, and the other electrode clamp can be connected to high voltage, allowing for a withstand voltage test of the insulating rod body. This completes the testing of the insulation and withstand voltage performance of the insulating rod, which helps to shorten the testing cycle of the insulating rod body and improve testing efficiency.
