“…Hence, reduced thermal boundaries and improved thermal conductivities act as a barrier for electrical stress to impact the polymer blend by improving the dielectric strength. 34 , 36 Other characteristics of polymeric insulants, such as volume resistivity (ρ v ) and surface resistivity (ρ s ) values, vary as a function of temperature from cryogenic to ambiance. The mean free path as well as free volume increase when volume and surface resistivities of the samples are reduced.…”

In this work, we have investigated the impact of micro-silica (SiO 2), micro-alumina-trihydrate (ATH), and mixture of micro/nano-sized particles (ATH þ SiO 2) on electrical, tracking and erosion, and water absorption characteristics of silicone rubber (SiR)-based novel composites. SiR-blends with varying concentrations by weight percent (wt%) of ATH and SiO 2 were prepared by simple blending in a two-roll mixing mill. Tracking/ erosion and water absorption resistance properties of SiR-blends were analyzed using the inclined plane test and water immersion tests, respectively, according to ASTM standards. Dielectric strength, volume and surface resistivity, tracking/erosion resistance, and water penetration resistance properties of SiR composites were determined and discussed. SiR composites with ATH showed enhanced dielectric strength, volume and surface resistivity, erosion resistance, and initial tracking voltage compared to SiO 2filled composites. Further, the ATH and SiO 2 co-filled specimens showed better water immersion resistance compared to samples only filled with ATH or SiO 2. We presume characterization results presented in this work will help researchers to optimize the performance of SiR for outdoor high-voltage insulation applications.

“…In recent years, the base materials with micro- and nanofillers are reported to offer enhanced corona, tracking/erosion, thermal and electrical characteristics. 16 -19 The previous researches indicated an improvement in the performance of silicone rubber by the addition of a small amount of fillers. 2,20 In an organic polymer, sometimes an inorganic filler is added to improve the properties of the base material, such as improved thermal stability, breakdown strength, and rigidity.…”

Multiple environmental stresses produce complex phenomena of aging in polymeric insulators. The main aim of this research is to investigate the improved aging characteristics of silica (SiO2)/alumina trihydrate (ATH) hybrid samples (HSs) in high-temperature vulcanized rubber. For this purpose, three HSs comprising 20% micro-ATH with 2% nano-SiO2 (S2), 4% nano-SiO2 (S4), 6% nano-SiO2 (S6) along with sample-virgin (SV) are subjected to long-term accelerated aging of 9000 h. A special aging chamber is fabricated for the aging process of samples. The aging characteristics of these samples are investigated by measuring leakage current (LC) and hydrophobicity classification (HC) after every weathering cycle. Similarly, Fourier transform infrared (FTIR) spectroscopy is performed to observe the important structural changes over the entire aging time. The dielectric strength of AC is also performed after every 1000 h of aging. Tracking and erosion resistance and mechanical properties are also investigated before and after aging. From the critical investigation, it is observed that HSs possess improved results in all the conducted tests. S2 has the lowest LC and HC values throughout the aging time. Similarly, S6 described the highest breakdown strength at the end of the accelerated aging. In the case of FTIR, it is analyzed that the important wave numbers remain intact for all the HSs in the accelerated aging environment. The loss percentage in the wave number for SV is higher, compared to the HSs. After performing the tracking and erosion resistance test, HSs have superior performance. For some of the mechanical properties, HSs showed improved values. Thus, from the experimental analysis, it is deducted that the sample S2 offers the highest resistance to the aging conditions, compared to the SV and other HSs.

“…3 The degradation of inorganic insulating material can be avoided by replacing the polymeric insulators highly resistant to direct sunlight, air contamination and rain. 4 SiR is also called as poly dimethyl siloxane since its chemical structure contains organic hydrocarbon methyl group (–CH 3 ) as a functional substituent and inorganic siloxane (Si–O) as the backbone. 5 Ethylene propylene diene monomer (EPDM) has good mechanical properties since it possesses a saturated structure with polymer backbone and also it is inexpensive compared to SiR.…”

The aim of the research is to prepare a polymer composite material for high-voltage cable insulation purposes. Many researchers have blended a silicone rubber (SiR) and ethylene propylene diene monomer (EPDM) at different ratios to identify the composition which possesses excellent electromechanical properties. SiR-EPDM blends in 90:10 and 10:90 ratios were taken up for this study. To these polymer blends, metallic filler titanium dioxide (TiO2) with different densities have been used as the filler materials. The electromechanical performance and the physico-chemical behaviour of SiR-EPDM blends with filler addition were compared with SiR-EPDM blends of the same blend ratio without filler. The electromechanical parameters were measured according to the International Electrotechnical Commission (IEC) and ASTM standards. The surface morphology and filler dispersion were examined by the scanning electron microscopy images. The elemental compositions of the samples were obtained from the energy dispersive X-ray analysis. The changes in electromechanical behaviour of the samples were analysed from Fourier-transform infrared spectroscopy results. The investigations reveal that 5 wt% of high-density TiO2-filled SiR-rich blend possesses the best electromechanical performance of all prepared samples.
