AHA is a three-layer flexible laminate consisting of polyimide film between two layers of aramid paper. The polyimide core supports high-temperature electrical insulation, while the aramid outer layers protect the film against mechanical stress during processing and installation.
AHA is a three-layer flexible laminate consisting of polyimide film between two layers of aramid paper. The polyimide core supports high-temperature electrical insulation, while the aramid outer layers protect the film against mechanical stress during processing and installation.
It is used in dry-type transformers, reactors and other equipment designed around a high-temperature insulation system.
