ABSTRACT:
This disclosure teaches an electrical insulator with improved glaze to pin electrical connection. A suitably contoured porcelain insulator shell is coated with a semiconductive glaze and has a metal cap and a metal pin each situated at a surface of the insulator shell opposite to the other. The insulator shell forms a recess to receive the pin and Portland cement is poured therein for mechanically securing the pin embedded in the insulator shell. A phenolic polymer composition is applied to cover the surface of the Portland cement to connect the pin electrically to the glaze and thus to accommodate passage of leakage current.
