Abstract Nanocomposite has been applied widely in dielectrics and electrical insulations due to its extraordinary electrical insulation properties. In order to get a better performance of epoxy resin insulation material, the nano aluminum nitride (AlN) which has been surface-treated by silane coupling agent is mixed in epoxy resin, AlN/epoxy composites with mass content 0%, 0.5%, 1%, 3%, 5%,7% of AlN are prepared by solution blending, and insulation properties of AlN/epoxy composites are researched. The results show that the effective integration between the resin matrix and AlN filler improves the thermal stability of the epoxy resin. The AlN particles reduce the volume resistivity and increase the dielectric loss factor of composites, but have little effect on the electrical insulation properties.When with 3% of nano particle, the breakdown strength of AlN/epoxy composites increases significantly. Therefore, it can improve the electrical insulation properties of epoxy resin dry-type transformers by mixing in appropriate nano-AlN particles.

Key words： Nano-AlN epoxy resin volume resistivity dielectric loss factor AC breakdown field strength
