25kV 200A Bushing Insert – Reliable and Flexible Termination for Medium Voltage Systems

Winding Wire’s 25kV 200A Bushing Insert provides a dependable interface between a loadbreak elbow connector and a universal bushing well, enabling safe and efficient loadbreak operation in medium-voltage distribution systems. Designed for pad-mounted transformers, switchgear, and junction cabinets, this bushing insert converts a standard bushing well into a fully operational loadbreak interface, compliant with IEEE 386 standards.

Manufactured from high-quality peroxide-cured EPDM rubber and corrosion-resistant copper alloy components, our bushing insert ensures long-term electrical reliability, thermal stability, and excellent mechanical strength, even in harsh environments. Its compact, dead-front design ensures safe live-front operation and is fully submersible for use in demanding underground distribution networks.
