Stress grading with novel 2D materials in cable systems rated at transmission voltages

A key pre-breakdown phenomenon in polymer is electrical treeing, which are microscale tree-like hollow channels growing within the solid insulating material. This is a well-established cause that leads to the eventual failure in cable systems. The aim of this project is to explore design and fabrication of nanoscale layered structures within existing insulation design using 2D nanomaterials. The hypothesis is such approach could more effectively manage the electric field stress at elevated voltage level than existing material/design. To tackle this research, fundamental materials science must first be considered to examine how nanomaterials could improve stress grading in cable insulation, and how to upscale laboratory scaled samples (a few mm) to full-scale cable system geometry. There is little published literature regarding the fracture mechanics of polymers/nanocomposites for application in cable systems. This work will generate new data on the use of 2D materials in cable structure leading to potential improvement in the selection of materials and design of cable systems.
