“…This shows that at higher temperature the Langmuir model breaks down, as it predicts a steady increase. A possible explanation for the qualitative differences at higher temperatures, is that the NaCl solution irreversible changes the substrate composition, through matrix degradation and/or fillers dissolution as explained in 2.2 [9,10,23]. The mechanism of this degradation will be further analyzed in the Sections 4.5, 4.6 and 4.7.…”

In this paper, the permeation properties of three types of liquids into HTV silicone rubber with different Alumina Tri-hydrate (ATH) contents had been investigated by weight gain experiments. The influence of differing exposure conditions on the diffusion into silicone rubber, in particular the effect of solution type, solution concentration, and test temperature were explored. Experimental results indicated that the liquids permeation into silicone rubber obeyed anomalous diffusion ways instead of the Fick diffusion model. Moreover, higher temperature would accelerate the permeation process, and silicone rubber with higher ATH content absorbed more liquids than that with lower ATH content. Furthermore, the material properties of silicone rubber before and after liquid permeation were examined using Fourier infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM), respectively. The permeation mechanisms and process were discussed in depth by combining the weight gain experiment results and the material properties analyses.

“…A few diagnostic techniques which have been commonly used are discussed in Aging of polymeric arrester (or insulator) housing materials is not closely related to the magnitude of leakage currents on the housings. This has been demonstrated by many researchers [3]. As an example, one can often measure much higher leakage currents or watts loss on porcelain housed arresters than on polymer housed arresters, yet one would not claim that porcelain housings age more rapidly than polymer.…”

Polymer housed surge arresters, evaluated under accelerated conditions of a Florida coastal climate, are shown to exhibit an increasing watts loss characteristic with service life corresponding to aging of the polymer housings. Surge arrester housings made of materials other than silicone rubber are shown to age more rapidly and therefore, show significantly higher watts loss with service life. Lifetime energy costs of polymer housed surge arresters, will need to factor in the watts loss of the housing due to wet surface contamination.

“…Water of hydration could hinder the physical accumulation of residue on the surface, because of the physical cleaning action of the water on the surface [33], [34]. In particular, the water of hydration released during the dehydration of ATH may scatter the residue.…”
