Volume Resistivity Properties of Cross-linked Polyethylene for Ultra-high Voltage Cable

In this paper, the physical and volume resistivity properties of cross-linked polyethylene (XLPE) for ultra-high voltage investigated due to temperature dependence, and the measurement of volume resistivity used to highmegohm meter is measured from 1 to 30 minutes when the each applied voltage, for example, DC 100[V], 250[V], 500[V] and 1000[V] is applied, 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[$^{\circ}C$].
