The new Buddy Bushing from LineWise increases the lifespan and strength of the crossarm attachment in transmission lines. Designed by Buddy Phillips, a Georgia Power line specialist with more than four decades of experience, the innovative device is a cost-effective measure that mitigates wear issues, inspection time and expensive repair or replacement.
The key to the Buddy Bushing is its unique two-part construction: an inner hub of 17-4 stainless steel and an outer hub of 416 stainless steel. These differing steel hardnesses prevent galling between the surfaces, while the Buddy Bushing’s unique design eliminates the sawing action that previously caused insulator attachment holes to fail. It can be installed on partially worn attachment holes to stop failure, or placed in new construction to extend the life of an arm. Third-party tests prove that not only does the Buddy Bushing solve wear problems, but it also increases joint strength by 25 percent.
Georgia Power’s field workforce installed a number of Buddy Bushings on 230-kV lines through its service territory, effectively reinforcing hundreds of worn crossarms. They found technicians required minimal training to install the device, and the savings on a single project for labor, equipment and materials were significant.
