Abstract
This paper introduces the findings of a detailed study on breakdown voltage strength under DC voltage and the development of HVDC cable. Recently, Nano-fillers are attracting attentions of many researchers and engineers, since they seem to bring higher potentials for advancement of electrical insulating properties as nano-composites. Additives and fillers are often adopted to polymeric materials for improving insulating and machanical properties. We have improved the polymer composition and developed a new insulation material for HVDC cable. Each specimen blended at LDPE1 to antioxidant, LDPE2 to antioxidant, pure XLPE was manufactured respectively. The insulation performances of the proposed insulator were compared with specimens blended at nano powders. DC breakdown strength of LDPE1 specimen at 90[
