New developments in transmission compression technology are limited due to the success and reliability of the standard two-die compression systems available. Most full-tension compression accessories suitable for elevated conductor temperatures require two sizes of dies for installation, as well as field-injection of filler compound. A compression system that involves only a single die set without requiring filler compound would simplify power transmission line construction.
With a continual need for new construction and replacement of existing aerial conductors, in conjunction with a new generation of linemen, efficiency is critical for installation – including speed, consistency and reliability. The new ANSI-qualified AFL SOLO HD® compression system utilizes a specialized core grip to eliminate speculation from the compression process, removing obstacles and providing a consistent and quality installation.
