CASE HISTORY SPOTLIGHT: Case History #619: Clamp and Powerline Protection
March 14, 2024
Not long after installation, clamps and surrounding areas on powerlines at a wind power transfer station corroded badly due to the severe environment of strong wind and blowing sand near the ocean.
Power was turned off to do restoration work. After taking the clamps down and mechanically removing most of the corrosion, workers cleaned the clamps in VpCI®-415, dried them, and sprayed ElectriCorr™ VpCI®-239 inside most of them. They reinstalled the clamps and applied a VpCI®-396 primer coat to the clamps and sections of wire on both sides. The clamps were top-coated with VpCI®-384.
Around the substation, workers applied VpCI®-368 removable coating to moving parts and applied MCI®-2020
to concrete support structures. MCI®-2005 was added to a large sand containment wall on the wind farm.
Together, these materials provided an integrated solution to help critical components hold up longer in an aggressive environment.
