Silicone rubber (SiR) is an important insulating material in high-voltage cable accessories. Electrical tree is a typical electrical aging inside SiR insulation and will cause breakdown when it reaches the ground. The tree characteristics may be changed by the cryogenic temperature because of the changing physicochemical properties. Besides, at temperatures above 273 K, addition of nanoparticles into...
With the continuous expansion of the power system, security and stability of the power distribution network is particularly important. As the power distribution equipment's main insulation, heat-shrinkable material has caused great concern of the department of operation and maintenance. Based on plenty of experimental results of the heat-shrinkable material with different operating time, the elongation...
