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

Controls Oscillation and Aeolian Vibration. Wake-Induced Oscillation is a swinging motion, like a pendulum, that is caused when wind blows across a bundle of conductors. As the conductors move back and forth, there is a potential of the conductors to touch, thus causing significant damage. [Ref. 1] - Area Notes
