On the effect of the structural properties of polyethylene on the DC conductivity in the temperature range from 40° C to -80° C
Measurements of the flowing current under the effect of DC fields were conducted using relatively thick samples (1.8 mm) of three different materials: plain low density polyethylene (LDPE), crosslinked polyethylene (XLPE), and 1-wt% TiO2 doped LDPE. The measurements were performed over a range of temperatures from 40°C to 80°C and at electric fields as high as 3×105 V/cm.
Results indicate that the observed DC conductive characteristics are different for the three materials. Those differences are attributed to the differences of the chemical and morphological structures of the materials used. Scanning electron micrographs seem to support this finding
