Ever see anything like this? This is insulated (fiberglass reinforced resin?) silver plated copper 12kV bus from electrical switchgear. Where it passes between switchgear sections it rests (snug fit) in a porcelain insulator, mounted in a window to the next section. This is where the corrosion occurred. Switchgear is in a non-conditioned central plant in S California and is about 30 years old. Third photo is the same corrosion point, with the insulation removed.
Any way to prevent this?
