A dielectrically-resistant system includes a first component of a first plastic shell having opposed and spaced apart walls, defining a first cavity. The first plastic shell includes a first rib. Disposed within the first cavity is a first in-situ foam core including expanded polymer beads. The first in-situ foam core has a thermal bond with the first plastic shell. A second plastic shell and in-situ foam core component essentially mirroring the first component is connected to the first component by a connection. The dielectrically-resistant system is capable of resisting an electric potential difference of at least 50 kV.
