Analysis of Insulation Properties for High Voltage Applications – A Review

Abstract

Four popular plastic polymers (LLDPE, XLPE, LDPE and HDPE) that are frequently utilised in high voltage applications are thoroughly examined in the review. It highlights how crucial it is to choose the right insulating material based on your needs. HDPE is perfect for pipes and packaging due to its density and crystallinity. Because of its superior mechanical and thermal properties due to the cross-linking process, XLPE is the material of choice for electrical insulation. The low density, impact resistance and flexibility of LDPE are well known. The essay also examines initiatives to improve these materials, such as the use of nanofillers for XLPE in HVDC cable applications and the addition of alumina nanoparticles to HDPE to boost its dielectric qualities. In conclusion, XLPE excels in thermal stability and electrical insulation, HDPE in toughness and chemical resistance and LDPE in flexibility and impact resistance. The best material to use depends on the needs of the high voltage application. Overall, the essay offers a complete analysis of the characteristics and possible applications of LLDPE, XLPE, LDPE and HDPE in high voltage insulation.
