Presentation

Insulation materials on aluminum conductors provide solutions for aerospace challenges

The increasing voltages used in aerospace and the altitude challenges create a need to provide innovation in insulation materials to reduce insulation damage due to partial discharge. The light weight of aluminum and its higher resistance to high-frequency eddy current compared with copper opens opportunities for aerospace usage. The presentation will report results on the oxide coating of aluminum and compare this coating with results from enamel- and PEEK-coated aluminum wires. We will discuss the effect of the insulation properties on the thickness and degradation of the coatings in operational conditions. Thermal properties will also be reported.
