To install a helical rod splice, the damaged or weak hole is first drilled out to a larger diameter. Then, the helical insert is threaded into the enlarged hole using a special installation tool. As the insert is twisted into place, it cuts new threads into the surrounding material, providing a secure and reliable connection.

Provides uniform spacing of horizontally bundled sub-conductors

Prevents sub-conductors from tangling due to gallop, ice unloading and fault currents.
