[Glass Insulators] The "Power" Of Toughened Glass

Insulators were first manufactured in the 1800s when the first telegraph and telephone circuits were put in place. Glass insulators were then produced in the 1850s for use with telegraph lines and, as technology developed, so did the technology regarding insulators, which were needed for telephone lines, electric power lines, and other applications. This article takes a look at a highly specialised use of toughened glass - insulators for power lines - presenting the products and production methods and technology used in this sector.
