How should an EHV (345kV -500KV) POC bushings be stored?

The preferred way to store an EHV 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. EHV bushings are too large to ship at the proper 7 degree angle, so if the bushing is stored in the shipping crate the air end of the bushing must be raised at least 7 degrees to keep the internal bushing core immersed in oil. The crate should be supported in several places to prevent damage. 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.
