Abstract
An adapter for use between a two-hole blade end fitting of a line post insulator arm and a Y-clevis bolt eliminates the need to replace the entire insulator arm when the end fitting fails or becomes distorted due to wear of the Y-clevis bolt. The adapter includes a body with a two-hole insulator end that connects to the end fitting and a single or double eye conductor end that supports the Y-clevis bolt. The conductor end is configured to align the load axis of the insulator arm with the Y-clevis bolt to transfer the tension load effectively through the adapter. Annular shoulders surround the two holes in the adapter back and the insulator end of the body. The shoulders extend into the bolt holes in the end fitting to center the bolts and form a clamp on the blade end to prevent further damage to the end fitting.
