| Abstract |
The international community's efforts to reduce greenhouse gases, a global environmental problem, are continuing, and as part of this effort, bio-epoxy resin, a sustainable and renewable resource, is emerging as an alternative. As part of this, research has begun to replace petrochemical epoxy resin used in heavy electric equipment for distribution and substation with bio-epoxy. Ten types of samples were prepared by mixing petrochemical epoxy DGEBA and bioepoxy ESBO in content ratio (phr). In addition, DGEBA/ESBO/M10_65wt% Mixture Composites 10 are used to replace insulation materials for heavy electric power distribution equipment.
A variety of samples were prepared. Among the various properties, the most important electrical properties, AC dielectric breakdown strength and dielectric properties, were evaluated. Among the electrical insulation breakdown and dielectric properties, DGEBA:ESBO= 70phr:30phr and DGEBA:ESBO=70phr:30phr/M10_65wt% Composites had the potential for commercialization in heavy electric equipment for distribution. |
