Polymer nanocomposite has recently drawn considerable attention because nanocomposites or nanostructured polymers have the potential of improving the electrical, mechanical, and thermal properties as compared to the neat polymers [1]. In this paper, the polymer nanocomposite was made by the mixed addition of SiO2 nanoparticle with the radio of 20 nm into room temperature vulcanized (RTV) silicone...
The use of Silicone rubber (SiR) is increasing as an insulating material of cable joint in power transmission line in recent years for its various excellent characteristics. However, few attentions has been focused on the influence of frequency on electrical tree characteristics. In this paper, room temperature vulcanized silicone rubber was employed as test sample to investigate the relationship...
In this paper, electrical treeing was investigated in room temperature vulcanized (RTV) silicone rubber (SiR) over a range of ambient temperatures. An ac voltage with a frequency of 50 Hz was applied between a needle-plate electrode to initiate the electrical tree at different ambient temperatures. Both the structures and the growth characteristics were observed by using a digital microscope system...
In this paper, XLPE laminate was employed as test sample to investigate the effect of cross-linking temperature on characteristics of electrical treeing. The samples were cross-linked at the temperature ranged from 150°C to 220°C by adding dicumyl peroxide (DCP) as cross-linking agent into low density polyethylene (LDPE). A pair of needle-plate electrodes was employed to initiate the tree by applying...
