Historical and Theoretical Background of XLPE

This chapter deals with the historical and theoretical analysis of crosslinked polyethylene (XLPE). The chapter is divided into three sections, the first section dealing with the historical developments in XLPE. This part depicted a historical picture of invention, the necessity of invention and finally its establishment as various XLPE products. Here gives a detailed discussion about the emergence of XLPE as the insulation cables, which is the most recognized application of XLPE and also other applications of XLPE like hip arthroplasty. The second section is a more in-depth presentation of classical and quantum mechanical theories behind the computational analysis. The final picture describes how various methods of computational studies in XLPE molecule parameterization and crosslinking reactions. This chapter is coverage of fundamentals in computational chemistry and a survey of most widely used force fields and software’s for simulation of polymer systems. Also, references to the theories used in the atomic simulation of the study of XLPE. Theoretical aspects of the mechanism of electrical treeing and UV radiation crosslinking process of polyethylene (PE) suggest some voltage stabilizers, antioxidants and crosslinkers for the future process of an efficient XLPE cable operating in high voltage.
