Porcelain Lightning Rod Insulators |
These insulators were used to insulate the rod itself from its mounting as well as the grounding cable that would carry the current to the ground down the side of the house or barn that these were normally used on. The vast majority of lightning rod insulators are made of glass, but there are a good number of porcelain styles, almost all in white. There is currently no hobby numbering system for porcelain LRIs.
Three styles of porcelain lightning rod insulators. The holes in the side allowed a wire to secure the grounding cable down the side of the house or barn. |
