| Abstract: | The paper analyzes the electric field of local heat on terminals of HV cross-linked cables; besides, local heat of sheath is inspected by use of infrared image and ultrasonic PD test. It is proved that local heat of terminal sheath relates to high magnetic field and improvement of local electric field can eliminate the heat on cable sheath. |
