In view of the burning loss and fire risk of T-type cable plug used in high voltage devices when the conductor is overheating, we built an experimental platform for the pyrolysis of rubber material for T-type cable plug , and the pyrolysis behavior of T-type cable plug was studied based on FTIR method. The results show that in the temperature range of 80-260℃, the pyrolysis characteristic components of T-type cable plug are silicone grease, CO2, and H2O. The escape temperature of CO2 and H2O is 80℃, and their concentration reaches the maximum value at 200℃, while the escape temperature of silicone grease is above 200℃, and the escape temperature increases with the increase of temperature. The results of non-isothermal thermogravimetric analysis show that the weight loss rate at 305℃ is 2.50%.
