Abstract
This disclosure teaches a direct current electrical insulator with improved glaze to pin electrical connection. A suitably contoured porcelain insulator shell is coated with a conventional non-conductive 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 in the insulator shell. A phenolic polymer composition is applied to cover the surface of the Portland cement to connect the pin for non-ionic current flow to the glaze and thus to accommodate passage of leakage current in a manner that generally prevents electrochemical corrosion of an anodic pin with attendant cracking of the porcelain insulator.
