Can electric insulating panels be used in outdoor substation enclosures?

Yes. Moisture-resistant phenolic paper laminates like Piedmont Engineering Grade® Insulating Panel are commonly used in outdoor substations and other electrical applications where humidity and occasional moisture exposure are expected. These materials are designed to resist moisture absorption and maintain dimensional stability. For installations with prolonged direct UV exposure, consult your Piedmont Plastics sales representative to ensure the material is appropriate for your project's environmental conditions.
