TOUGH ENOUGH TO PROTECT THE POWER GRID MODULAR BALLISTIC PROTECTION MADE POSSIBLE WITH COMPOSITES THE CHALLENGE Recent attacks on U.S. electrical substations across the country provide stark reminders that our nation’s power supply remains a primary target for criminals focused on harming our country and security.1 The call to action is evident: we must continually improve the physical and technological infrastructure protection of our nation’s energy supply. Using GlasArmor panels, Ballisti-Wall® and Ballisti- Cover® solutions enable utility companies to add a superior level of protection to critical components and meet FERC security requirements within a modular, adaptable construction. 1 https://www.nbcnews.com/news/us-news/three-substations- attacked-washington-state-rcna63214 2 https://www.ferc.gov/sites/default/files/2020-04/E-4_10.pdf © 2023, All Rights Reserved Avient Corporation, 33587 Walker Road, Avon Lake, Ohio USA 44012 To learn more about Avient’s advanced composite solutions, visit www.avient.com/composites.
