Abstract

In this paper, we estimated the insulation properties of cross-linked polyethylene (XLPE) for ultra-high voltage cable. we have studied the dielectric characteristics of XLPE due to frequency and temperature variation. The dielectric characteristics were measured in the temperature range from $25[^{\circ}C]$ to $120[{^{\circ}C]}$. Also we measured in the voltage range of 1[V] to 20[V] according to the step voltage application method. From FT-IR spectrum as an analysis of physical properties, a strong absorption in wavenumbers 700 to $730[cm^{-1}]$, $1456[cm^{-1}]$ and 2700 to $3000[cm^{-1}]$ observed by the methyl groups$(CH_{2})$. From the analysis of DSC, the crystalline melting points of the specimen observed in the temperature $60[^{\circ}C]$ and $106.58[^{\circ}C]$.
