Intresting Facts
All materials conduct electricity, some just oppose it better than others; hence an insulator.
The Albert Champion Company introduced the “X” spark plug in 1909
“The Champion “X” insulator is what is known as the petticoat
type. This insulator is generally conceded to be less liable to foul than
insulators of other types, due to the fact that the surface over which the
current must travel is greater. Furthermore, these insulators are able to
resist fouling, as they are made of material which will not absorb oil: the
glaze on the surface is smooth and hard so as to keep the oil from adhering
to it.”
Ford Service Bulletin No. 11 Monday, September 1, 1919 Page 81
“Insulators must be strong electrically. Every porcelain insulator
is called a di-electric. The material is an insulator at certain temperature,
while at others, it becomes a conductor.”
Ford Service Bulletin No. 11 Monday, September 1, 1919 Page 81
If the porcelain is fouled, it should be cleaned with a cloth dipped in gasoline.
