Abstract: The cable protection tube can protect the cable tube from damage and is easy to replace and check, so it is widely used in the construction of cable line. The Vicat softening temperature is an important index reflecting the heat resistance of the cable protection tube. In this paper, an automatic sample preparation equipment for Vicat softening test of cable protection tube is developed and the main structure and working principle of the equipment are introduced in detail. The equipment has the advantages of simple operation, smooth sample preparation and short time consumption, which makes it has broad prospects in engineering applications.
