Fiberglass crossarms are increasingly used in overhead distribution lines as utilities require components that maintain strength, resist corrosion, and reduce long-term maintenance. With a consistent structure and reliable insulation properties, fiberglass crossarms provide a practical and cost-effective solution for both new installations and pole upgrades. This article explains the technical considerations, installation advantages, and application scenarios relevant to utility engineers and procurement teams.
FRP crossarms are increasingly used in power distribution networks as utilities look for longer-lasting, low-maintenance components to replace wood and steel. Their corrosion resistance, insulation performance, and long service life make them suitable for various installation environments, including coastal, humid, and industrial regions. This article presents a practical, engineering-focused overview of how FRP crossarms support distribution line stability, installation efficiency, and long-term asset management.
Utilities are moving away from traditional wooden and steel arms as maintenance costs rise and field reliability requirements increase. Composite crossarms, especially fiberglass crossarm systems used in distribution networks, offer consistent long-term strength, excellent dielectric performance, and complete corrosion resistance. This article explains why composite structures have become a preferred choice for modern utilities and how they support long-term grid stability.
