Abstract

We show results that examine about electrical properties of XLPE insulated 6.6kV cable termination by mechanical damage. The cable used to produce the cable termination is 6/10kV tray XLPE fire retardant electric cable (6/10kV TFR-CV $35SQMM{\times}1C$) which is domestically made. We apply force to XLPE insulator and made mechanical defect using knife. Defected samples go through the withstand voltage test according to the IEEE std. 48 test regulations and lighting impulse (hereunder, IMP) withstand voltage test regulations. Then the effects of the scars shown during the construction process on electric accidents at the end part are analyzed.
