Study of Electrical Tree Growth Properties in Cross-Linked Polyethylene

ES Materials and Manufacturing
Polymer insulation materials are subjected to long-term exposure to high-voltage electric-field environments. In the field-strength concentration region, the electrical tree grows, causing insulation degradation.
