Fiber-reinforced polymers versus traditional cross arms materials
BY JANOS TOTH & GRANT LOCKHART, FRP Transmission Innovations Inc.
Recently, utilities have started using newer options such as component polyurethanes instead of older, widely used conventional materials. Specifically, fiber-reinforced polymer shows promise in providing reliable, cost effective, and durable support for conductors, under challenging environmental conditions. This issue’s Overhead T&D Channel weighs the pros and cons of traditional cross arm materials and makes the case for use...
Resiliency is a term used more and more by transmission line stakeholders including designers, operators, and owners. Resilience is simply defined as toughness or the capacity to recover quickly from difficulties. It can be used to describe a system, an object or even a person. Dr. Ginsburg, child...
INTRODUCTIONIn 2005 an article about toughened glass insulators (TGI) titled “Return to Clarity” was published. Fifteen years later, this sequel article by a team including the two original authors, picks up where the former concluded with optimism about the future of TGI technology...
In a strategic move aimed at enhancing its power supply reliability, FirstEnergy is actively exploring alternatives to the PJM capacity market. This development reflects the company’s proactive approach to addressing challenges within the existing market structure and ensuring a more robust...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...

Sediver has established in the USA an assembly factory for glass insulators in 2017 but also, and perhaps more interesting for some engineers, a laboratory capable of performing all the tests required by the world’s standards. Large test campaigns have already been conducted in this...
Insulators under fire, what are we talking about? A line directly in the fire is considered as lost A line near the heat of a fire can be saved What is the condition of insulators on a line nearby a fire? Reliability of insulators during or after a fire is a key consideration for T&D...
