Context

Country: Canada
State/Province: Ontario
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: To suppress wind-induced vibrations on transmission lines.
Technical: Vibration dampers are used to suppress wind-induced vibrations on transmission lines. These vibrations cause alternating bending strains in the conductor, which are superimposed on the static tensile and bending strains. This can result in conductor damage at the clamping points, ranging from fatigue breakages in single wires to breakage of the complete conductor. The vibrations spread via the suspension and tension fittings to the mast and lead to problems such as shaking out of joints to breakage of mast struts. The damper is designed to reduce vibration. [Ref. 1]
Area Notes: Unknown
