Performance Analysis Based on Thermal Aging Tests of Sol-Gel and Polymer Insulated Wires by Enameling and Extrusion Technology

This research activity aims to evaluate electrical insulation system (EIS) intended for machine winding wires. The evaluation is based on mechanical, thermal, and properties tests following international standards enameled Dielectric parameters such as dissipation factor, partial discharge inception voltage (PDIV), parallel capacitance, resistance behavior of different insulator configurations twisted-pair samples are observed during thermal aging tests. Those formed combinations dielectric layers conventional polymers (polyester-imide (PEI), polyamide-imide (PAI), polyimide (PI)) used coating A study using two mineral varnishes (silica-based) obtained by the sol-gel process integrated these classical enamels an outer layer extrusion thermoplastic polymer with without fillers. Given high consummation energy use unsustainable materials involving production wires, principal interest this work exploit new wire produced, less environmental impact than ones. investigates filled resins performance insulating influence solutions (mineral varnishes) insulated increase class.
