Infrared Study On The Aging Of The Heat Shrinkable Cable Accessories

By using infrared spectrum analysis to examine the heat shrinkable cable accessories, from the perspective of functional groups and the changes of chemical bonds to reveal the aging mechanism of the heat shrinkable cable accessory. The study concluded that high temperature and low humidity environment lead the high molecular polymer have hydrolysis reaction, prompted changes in functional groups and chemical bonds, so as to change the physicochemical properties of the cable accessory. The research in this paper provides a feasible direction and reference for further study on the mechanism of fade-proof and anti-fading of the power accessory.
