Evaluation of long-term reliability of power cable including nano-conductive layer

The internal and external semiconductors in the power cable have semiconducting properties and serve as a polymer material to prevent the concentration of electric fields that may occur between the insulator and the conductor and to uniformly distribute the electric field radially. In this paper, we will construct a model cable using commercial and Nano-semiconductor and evaluate long-term reliability by measuring VLF (Very Low Frequency) TD (Tan Delta).
