Unveiling the degradation and stability of the insulating properties of Epoxy/CaCO3 derived from snail shell bio-composite
High-voltage insulators were developed from CaCO3 derived from waste snail shell to replace the low-impact energy ceramic insulators. The 15 wt% CaCO3-snail shell/epoxy composite was produced using the solution stir-cast method. The UV radiation test, breakdown and flashover voltages, mechanical properties, tracking, and erosion depth of the developed composite were determined. A 116.7 and 43.82 % enhancement in the flashover voltage and leakage current was obtained at 1000 h of UV ageing. The developed insulator has longer thermal process breakdown strength and increased high-temperature insulation resistance. The properties attained in this work are within the acceptable range for high-tension insulator applications.It was established that waste snail shell could be used in the production of high-voltage insulators with high ultraviolet radiation resistance.
期刊介绍：
Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
