Period

This type made c. 2008, and used until 2010. This example appears new/unused.

Canada

The [lot] donation includes insulators, dampers, conductors, a preform rod, a sign, and personal gear from a Hydro One transmission station. It shows choices made by Hydro One, the typical equipment used at the beginning of the 21st c. on high voltage lines in Ontario. The artifacts also represent diversity and the longevity of manufacturers of electrical equipment and globalization of the markets. [Ref. 1]

Function

Used in electrical power transmission to separate conductors to prevent a flow of current between them or to other objects.

Technical

Porcelain insulators are more durable than polymeric; they are heavy and therefore are used on lower voltage lines that do not require a long insulator sequence. NGK has been producing insulators since in 1919. This is a high quality insulator; reliable with excellent long-term performance. Mechanical strength up to 530kN, is very high. [Ref. 1]
