Overhead Line Pin Insulator

The Overhead Line Pin Insulator 55-4 is an ANSI-standard model designed for overhead lines. Its rated voltage is 13.2 kV. The structure height is 127 mm, and the disc diameter is 142 mm. The mechanical failing load is 11 kN. This product complies with ANSI C29.5. The creepage distance is 229 mm, while the dry arcing distance is 127 mm. The 13.2 kV rating is commonly used for distribution applications in North America. This model follows the standard 55-series configuration for this voltage class. The disc diameter is larger than those of lower-rated models, and the creepage distance is also longer. These features provide a longer surface path for outdoor operation in rainy or foggy conditions. The porcelain material has been optimized through multiple formula adjustments to provide high mechanical strength and stable electrical performance. This Overhead Line Pin Insulator is mounted on 13.2 kV overhead line straight poles and tension poles.
