C56-08a-273067Transformers are one of the most essential components of electric grid power distribution. The key cause of transformer failure is overheating, which becomes more likely over time due to breakdown of its insulating materials such as kraft paper, an important heat dissipation and insulating component between copper windings. Kraft paper has low thermal conductivity, which causes “hotspots” to develop and eventual thermal breakdown of the cellulose molecules of kraft paper. The available transformer failure statistics reveals that the typical service life of transformers which fail due to “insulation problems” is 17.8 years, less than half of the expected lifetime of 40 years, and 75% of high voltage transformers’ collapse is originated by dielectric insulation issues mainly stemmed from the kraft papers. This existing problem, along with development of future high voltage network and smart grids requires higher-performing insulation systems to deal with more dynamic and volatile conditions. Capitalizing on our promising preliminary results, the objective of this project is to integrate a collection of advanced surface chemistry, kraft paper fabrication, and rapid property screening, followed by standard testings and pilot demonstration to produce multifunctional insulating kraft papers with long lifetime for transformers. This project is expected to result in significant improvements in several performance metrics of the kraft paper including thermal conductivity, dielectric strength, moisture content, tensile strength, elongation at fracture, etc, that all ultimately translate to longer lifetime. C-Crete’s experience in projects with similar complexity along with our state-of-the-art facilities and equipment and relationships with key industry players will catalyze our commercialization efforts.
