The overheating defects of 35 k V cable terminal were found by infrared temperature precision measurement which were determined as voltage pyrogenic critical defects. The fault reason is a partial discharge caused by poor processing technology leading to partial charge and cable overheating. Previous failures of cable terminal were analyzed comprehensively

the standpoint that the key of cable installation quality is the quality of the cable stress cone is put forward. The key quality points of stress cone installation position is explained by net-vibes shrink terminal

and the several common project cable terminal extension program and the troubleshooting method of transport cable terminal stress cone installation process is recommended.
