The torque-to-capacity relationship for helical anchors and piles is an empirical method originally developed by the A. B. CHANCE Company beginning in the late 1950s. Today, the relationship is well recognized in the deep foundation industry. It is commonly referred to as torque correlation.
Electric Utility Engineers who design and maintain transmission lines face many challenges including weak, soft soils that can’t bear much weight and aggressive soil that corrodes metal. Whether you are facing Virginia’s Coastal Plain or western Colorado’s Mancos Shale, CHANCE® offers protection to ensure the helical foundations and anchors beneath transmission towers will function properly and withstand the test of time.
Responding to concerns that conventional brackets were difficult to install, Hubbell Power Systems, Inc. engineers designed a crossarm bracket that saves time, improves safety, and offers a better fit. The Hubbell Easy-On Crossarm Mounting Brackets are used for mounting cutouts, arresters, cable terminators, or cutout-arrester combinations to a distribution pole crossarm.
When utility crews are dealing with the aftermath of storms, they cannot forget to evaluate how the guy anchors have been impacted. Rebuilding the overhead lines depends more than ever on the holding capacity of the guy anchor.
