DuPont NOMEX insulation material is used to make dry-type transformers with high and low voltage windings. It has the advantages of flame retardant, self-extinguishing, moisture-proof, good heat dissipation performance and low noise. It can go deep into the load center, such as high-rise buildings, airports, docks, power plants, residential areas or complete sets of substations.
