Improvement of dielectric strength and properties of cross-linked polyethylene using nano filler

Power cables insulated with cross-linked polyethylene (XLPE) have been utilized worldwide for distribution and transmission networks. There are several advantages this type of insulation; it has better electrical, thermal, mechanical properties compared to other types insulation in medium high voltage Many studies aimed improve the XLPE characteristics through introducing nano fillers matrix. Therefore, paper investigates AC (HV) breakdown (dielectric strength) after adding nano-sized zeolite (Z) various concentrations 1 wt%, 3 5 wt% 7 wt%. The dielectric strength is tested different temperatures 30 ⁰C 250 ⁰C. Additionally, was low salty wet conditions. enhanced by inducing Z filler. results tests were used train artificial neural network (ANN) calculate composites filler under weathering Thermogravimetric analysis, tensile strength, elongation at break applied check thermal samples. Experimental findings show that optimum concentration 3.64 enhance properties.
