? Such transformers are normally potted in tar. However, you could
have one with a potting void. . On my Web site, a simple method of
potting transformers with polyester laminating resin is described. The
transformer needs to be removed in order to do the potting. The screws
that hold the laminations together need to be tightened before potting.
