In the early years of electrical insulation development, insulation material was mainly of an organic type such as natural rubber and natural resins. As the voltage levels increased, synthetic insulation material offered better solutions. Synthetic manufacturing processes are typically energy intensive and the materials are not environmentally friendly. Insulation that is based on synthetic material is therefore not compatible with the concepts of sustainable energy and enviroFiciency.


Researchers are seriously considering nanotechnology as a means of exploring possible breakthroughs in electrical insulation quality improvement.


Take note

  • There are shortfalls in electrical insulation performance.
  • Further improvement in insulation technology should be pursued.
  • Nanocomposite dielectrics is an attractive option.
