Process. Porcelain insulators are made from clay, quartz or alumina and feldspar, and are covered with a smooth glaze to shed dirt. The design of insulators often includes deep grooves, or sheds, that provides increased arc-lengths. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. Several companies had started making insulators from "dry ...

A Brief History of Porcelain Insulators
24/12/1995 · A number of other insulator manufacturers tried to make wet process porcelain themselves, including Fred Locke. At this time, a thick solid section of porcelain was difficult to produce; Imperial being the only expert in the technology. As a result, "glaze-welding" came into use. An insulator was produced in 2 or 3 "shells", or pieces. These pieces were glazed and then stuck together and fired ...
