In general, crosslinked polyethylene (XLPE) is Used as an insulation material for medium voltage or higher power cables. Despite its excellent insulating properties, XLPE generates harmful substances such as methane gas and acetophenone in the Crosslinking process, and it is a thermosetting polymer that cannot be recycled. For this reason, the demand for eco-friendly insulating materials of non-crosslinking type is increasing, and related studies are also actively being conducted. In this study, recyclable thermoplastic Polypropylene (PP) was used as the base resin, and the electrical insulation and mechanical properties were confirmed. In addition, by measuring the insulation breakdown strength of raw materials, the insulation characteristics of each material wrer confirmed, and the efect of applying them to the compound was confirmed. We found a composition with excellent tensile strength, flexibility, heat resistance and AC breakdown strength (ACBD). |
