Composite Cross-Arm Post Insulator

Composite cross-arm post insulators are used in overhead transmission and distribution lines to support and insulate conductors. They are made with a fiberglass core rod, silicone rubber sheds, and metal fittings, providing high mechanical strength, reliable insulation, and excellent resistance to pollution and weathering. Compared with porcelain insulators, they are lighter, easier to install, and offer superior anti-aging and contamination performance, ensuring long-term reliability of power lines.
