How should a low voltage (15kV – 69kV) POC bushings be stored?

The preferred way to store a LV POC is to keep them vertical in a proper stand which cannot be tipped over. The preferred location is indoors; however, bushings may be stored outdoors. If you intend to the leave the LV POC’s in the shipping crate the crates must be placed in the vertical position and supported so they don’t tip over or the air end of the crate /bushing must be at a 7 degree angle above the oil end to keep the core immersed in oil. If the bushing is left in the crate it should be inspected for weather damage as the crates are not designed for extended outdoor storage. For long term storage, water may gather inside the bags covering the upper and lower ends, so it’s recommended that a water repellent grease be applied to the top and bottom terminals and mounting hardware to protect the contact areas from corrosion.
