Water Treeing in Polyethylene Cables
This review discusses water tree growth in polyethylene cable insulations. The characteristics of water trees, the
effect of aging parameters on water tree growth and the possible mechanisms of growth are considered, emphasizing vented
tree development in polyethylene insulating materials. Moreover, test methods and measures to reduce water treeing are
