Abstract

In this paper, the physical and electrical conduction properties due to the electron beam irradiation for low density polyethylene using insulating materials of the distribution cable and ultra-high voltage cable are studied. In FTIR spectrum for physical properties, the strong absorptions by methyl groups in wavenumbers 720[$cm^{-l}$] and 1463[$cm^{-l}$] are observed, and the effect by residual carbonyl groups (C = 0) is hardly appeared. So, as a result of the electrical conduction properties, it is confirmed that the conduction current is increased nearly to 50[$^{\circ}C$], and is not changed until the crystalline melting point from the temperature over 60[$^{\circ}C$] because of the defects of morphology and the formation of many trap centers by means of electron beam irradiation.
