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