"The technique means that the wires do not need conventional epoxy and glass fiber insulation to ensure the flow of electricity. While simplifying construction, the technique also lowers costs. “The costs to wind the coils are much lower because we don’t have to go through the expensive and error-prone epoxy vacuum-impregnation process,” Zhai said. “Instead, you’re directly winding the conductor into the coil form”
