An insulating rod pressure resistance test platform relates to the power supply experiment equipment field. A pedestal is provided with a track. The track is provided with a support column. One end of the support column is connected to the track through a sliding apparatus. The other end of the support column is provided with a fixing apparatus. The fixing apparatus is formed by a high pressure fixing end and a grounding fixing end. The high pressure fixing end and the grounding fixing end are formed by upper pressing plates, lower pressing plates and telescoping supports. Each telescoping support is arranged between each upper pressing plate and each lower pressing plate. Each lower pressing plate is connected to the support column. The sliding apparatus is formed by a clamping shaft, a pulley and a clamping groove. The clamping shaft is connected to the support column. The clamping shaft is arranged in the clamping groove on the track. The clamping shaft is provided with the pulley. Each telescoping support is formed by a first support rod, a second support rod and a connection shaft. Two ends of the first support rod and the second support rod are connected to the upper pressing plates and the lower pressing plates respectively. The first support rod and the second support rod are connected through the connection shaft. Practicality of the platform is high and test work of work personnel becomes convenient.
