Abstract

Polymer-based insulators offer major benefits as compared to customary insulators. In the current research, efforts are conducted to enumerate the effect of µATH (Micro Aluminum Trihydrate) and nSiO2 (Nano silicon Di-oxide) fillers loading on to electrical, mechanical, thermal, and tracking resistance properties of Silicone Rubber-RTV/µATH@nSiO2 micro/nano composites for high voltage insulation. The UV-vis and FESEM characterizations were conducted to see the optical behavior and uniform dispersion of all fillers into base material before and after mixing. The prepared composites A, B, and C with wt.% concentrations of the 100% Silicone rubber, (15 wt.%µATH@Silicone rubber), and (15 wt.% µATH@nSiO2@Silicone rubber) respectively were tested for electrical, mechanical, thermal, and tracking resistance properties measurements. The characterization result for all samples A, B, and C indicates that all micro and nanocomposites had high voltage insulation characteristics with the loading of micro and nanofillers in pure silicone rubber. Silicone rubber was been mixed with varying concentrations of (15 wt.%µATH@Silicone rubber) and (15 wt.% µATH@nSiO2@silicone rubber) by using a roll milling sulfur cure system. The outcome that arises from the present research highlighted that the dielectric breakdown has increased with micro and nanofiller loadings which are about 120KV, 179KV, and 190KV for samples A, B, and C correspondingly. Similarly, the surface resistivity was noticed (3.3 × 1014, 5.5 × 1014, and 8.4 × 1014) Ω/Square for all three samples A, B, and C sequentially. Also, the volume resistivity was been recorded as (1.14 × 1014, 4.5 × 1014, and 9.8 × 1014) Ω-cm-Square for all three samples accordingly. Based on all experimental results, it has been concluded that sample C with nSiO2 fillers loadings showed improved electrical, mechanical, thermal, and tracking resistance properties as compares to other samples and suitable for high voltage outdoor applications.

摘要

与常规绝缘体相比,基于聚合物的绝缘体具有重大优势。在目前的研究中,努力列举了 µATH(微三水合铝)和 nSiO 2(纳米二氧化硅)填料对硅橡胶-RTV/µATH 的电气、机械、热和抗电痕性能的影响用于高压绝缘的@nSiO 2微/纳米复合材料。进行 UV-vis 和 FESEM 表征以观察混合前后所有填料在基材中的光学行为和均匀分散。制备的复合材料 A、B 和 C 具有 wt.% 浓度的 100% 硅橡胶、(15 wt.% µATH@Silicone Rubber)和(15 wt.% µATH@nSiO 2 @Silicone Rubber 分别进行了电气、机械、热和抗漏电性能测量测试。所有样品 A、B 和 C 的表征结果表明,所有微米和纳米复合材料都具有高电压绝缘特性,在纯硅橡胶中加载了微米和纳米填料。通过使用辊磨硫磺硫化系统,将硅橡胶与不同浓度的 (15 wt.%µATH@Silicone Rubber) 和 (15 wt.% µATH@nSiO 2 @silicone Rubber )混合。本研究得出的结果表明,对于样品 A、B 和 C,介电击穿随着微米和纳米填料负载的增加而增加,相应地,样品 A、B 和 C 约为 120KV、179KV 和 190KV。类似地,注意到表面电阻率 (3.3 × 10 14,对于所有三个样品 A、B 和 C,依次为5.5 × 10 14和 8.4 × 10 14 ) Ω/Square。此外,所有三个样品的体积电阻率相应地记录为(1.14 × 10 14、4.5 × 10 149.8 × 10 14)Ω-cm-Square。基于所有实验结果,得出的结论是,与其他样品相比,具有 nSiO 2填料负载的样品 C 显示出改进的电气、机械、热和耐漏电性能,并且适用于高压户外应用。
