Extending the Life of Overhead Aging Assets with Focus on the Energized Portion of Transmission Line

CARL R. TAMM Classic Connectors, Inc USA SUMMARY The 21st Century has been deemed “The Era of Rebuilding.” Infrastructure around the globe, much built in the early 20th century, including roads, bridges, pipelines, and not to be ignored, our electrical…


A new Idea For: Grid Resilience, Wildfire Mitigation & Asset Management

The weakest link in any overhead system will always be connection points, such as; deadends, suspension clamps, and splices. Conductors and well-maintained towers will always outlast connectors. Even though some connectors fail due to mechanical stress,…


Overhead Powerline Mitigation Update

With wildfire season coming in hot this year due to record low precipitation this past winter, and with hurricane season in full swing, we want to take this opportunity to re-introduce ClampStar® as a simple and effective way to harden the grid.…


Mitigate Wire-Down Incidents and Wildfires

During a routine wildfire mitigation inspection on this 500kV 2300 kcmil, AAC line, a suspect repair sleeve adjacent to a suspension clamp was identified. Rather than taking a risk to spend time and money performing a detailed inspection and analysis of…


Conductor Repair After Spacer Damper Damage

Damage caused by worn Spacers, Spacer Dampers, Dampers, Aircraft Markers, or other line hardware - or lightning and gun-shot - is easily and quickly repaired. An Australian utility corrected conductor damage on a 29.3 mm O.D. transmission conductor using…


ClampStar Units Have Protected This Major Utility’s Transmission System For The Last Decade

Recently, an existing 230kV ACSR-SD (self-damping) transmission line was rerouted to a new substation approximately ½ mile away. To accomplish this task and to accommodate right-of-way allowance, 6 new monopoles were set in the approximate center of an…


Connectors, Clamps, and ClampStar® - How are they different?

Connectors: A connector can be defined as a device for joining two or more conductors to provide a continuous electrical current path. Connectors generally fall into four types; automatic, compression, wedge, and bolted. The electrical and mechanical…


How Engineered Mechanical Shunts Are Superior For Overhead Connector Repairs

Have you ever found yourself in a situation where you believed one thing to be true and then found out years later that it wasn't? For many years, experienced lineman and engineers believed that cutting out a splice on an overhead line and replacing it…


How To Properly Repair Damaged Conductor Caused By Spacer Dampers

Spacer dampers, designed to provide proper damping of wind-induced vibrations for bundled conductor lines, have been around for more than 50 years and like most hardware exposed to the elements, needs to be replaced at some point in time. Most often,…
