Abstract :
A study has been carried out about the electrical conduction properties of LDPE and XLPE film for power cables. As for increase of temperature, the current density of LDPE is increased with constant ratio in low electric field, but changes with exponential function in high electric field. The tunnel current of prebreakdown region is shifted toward low field as much as thermal excitation energy. XLPE shows dominant electrical conduction properties by thermal excitation energy in low electric field, and transformation of the electron is resisted by the crystal in high electric field
