Abstract

High-voltage insulators were developed from CaCO₃ derived from waste snail shell to replace the low-impact energy ceramic insulators. Taguchi-grey (GRA) multi-response analysis was experimentally used to assess the effects of the processing parameter. The multi-response variables chosen were the dielectric constant, water absorption, and impact energy. The findings show an optimal point of 15 wt% CaCO₃-snail shell, 120 °C curing temperature, and 6 h of curing time. The anticipated GRA was quite close to the experimental GRA at a 95% confidence level. This proved the effectiveness of the best processing settings. It was established that waste snail shell could be used in the production of high-voltage insulators that can withstand voltages up to 13.5 kV with high ultraviolet radiation resistance.
