ABSTRACT:
A method of making an amorphous metal transformer core includes the steps of providing an amorphous metal core having two legs which are connected by an upper and a lower yoke, wrapping each of the legs with a sheet of flexible material which is capable of withstanding, without degradation, the temperature which is required to anneal the amorphous metal core, and then annealing the amorphous metal core. An amorphous metal transformer core includes a stack of amorphous metal laminations, the stack being formed into two legs which are connected by upper and lower yokes in which the legs are wrapped with a sheet of flexible material which is capable of withstanding, without degradation, the temperature required to anneal the amorphous metal core.
