Do CCS Conductors Really Endure Stress Longer than Copper?

Published

on

BRENTWOOD, Tenn., June 5, 2024 /PRNewswire/ — For decades, Copperweld Copper-Clad Steel (CCS) conductors have been widely regarded as the paragon of strength and resiliency in the power grid and utility markets. CCS is used in some of the most unforgiving environments and applications — frost-heaving soils in substation ground grids, gale-force winds in pole-top transformer connections, and the unearthly cold and relentless radiation of space.

Copperweld CCS conductors displayed up to 5 times greater flex endurance than the equivalent copper samples.

CCS is trusted because it has proven its reliability and performance for nearly 100 years.

The Challenge
To back up CCS’s century-long reputation for superior strength, Copperweld’s engineering team received several requests from customers to perform lab tests that measure the flex-fatigue endurance of Copperweld CCS products compared to equivalent-ampacity copper conductors. So, they stepped up to the challenge.

Flex Fatigue Testing
In conductor manufacturing, breakload tests are popular for assessing conductor strength. Copperweld performs dozens of breakload batch tests every day to ensure that every foot of our CCS conductors is performing to specification. But while breakload tests are excellent for measuring tensile strength, they only measure mechanical strength across a single, linear event. Real-world abuse involves a wide range of motion and a high level of repetition.

Whether simulating the high-pressure contraction and expansion in buried applications or the repetitive stresses in overhead applications, an accurate way to measure real-world endurance is a flex fatigue test. Flex fatigue testing measures the number of stress cycles (180-degree bends) endured before conductor breakage is observed. A conductor’s breaking point is typically measured when continuity is interrupted. Unfortunately, stranded conductors expose an inherent limitation when simply testing for continuity.

Finding the True Breaking Point
Because a stranded conductor can maintain continuity after one or more strands have broken, a traditional flex-fatigue test that measures continuity disruption is more suited for single-end conductors. This method of testing endurance provides an unfair advantage to stranded conductors like our stranded CCS products. So, we devised a test method to more accurately and fairly measure the comparative flex-fatigue performance of both stranded and solid conductors.

This new test setup utilizes the sound spike created when a single strand of a stranded conductor breaks to identify the cycle at which the conductor is compromised, despite maintaining some conductivity. With this setup, a sound meter and monitoring software are used to cross reference elapsed test time of the sound spike (breaking point) with the number of bend cycles in the flex fatigue test. This provides a reliable method of testing the flex endurance for both conductor construction types. 

‍Our Test
To test the flex endurance of products that traditionally receive significant abuse in the field, we focused the study on our most popular transformer riser cables (Stingray 135 and Stingray 195) and their copper equivalents (6 AWG and 4 AWG). Pole-top transformer riser cables are subjected to a high level of shear force trauma in the form of flexing, bending, jerking, and vibration — making them ideal test subjects for this study.

In each test, five samples of each conductor — CCS and copper — were cut into two-foot sections with 1 inch of insulation removed from both ends to connect to the Flex Fatigue Tester. A Reed R8080 Sound Level Meter was then connected to monitoring software to capture single-end strand breakage. To mimic the extreme stressors that many conductors encounter in the field, we performed a standard 180-degree test consisting of a 90-degree bend to the left and a 90-degree bend to the right constituting a full cycle.

Stingray 135 vs 6 AWG Solid Copper Results
When comparing Copperweld CCS samples (Stingray 135) to solid-copper samples (6 AWG), CCS displayed greater flex endurance than copper. The average full-cycle count for the Stingray 135 samples was 224.8 cycles while the average full-cycle count for the 6 AWG copper samples was 36.2 cycles. This indicates that the CCS sample (Stingray 135) has 5.2 times more flex endurance than copper (6 AWG).

Stingray 195 vs 4 AWG Solid Copper Results
When comparing Copperweld CCS samples (Stingray 195) to solid-copper samples (4 AWG), CCS displayed greater flex endurance than copper. The average full-cycle count for the Stingray 135 samples was 87.6 cycles while the average full-cycle count for the 6 AWG copper samples was 30.6 cycles. This indicates that the CCS sample (Stingray 195) has 1.9 times more flex endurance than copper (4 AWG).

‍Conclusion
Using flex fatigue testing and sonic breakage detection, Copperweld CCS conductors displayed up to 5 times greater flex endurance than the equivalent copper samples.

Whether it’s for overhead tap wire or below-grade grounding for a substation, CCS can be the perfect solution for upgrading system design strength and meeting your electrical performance needs.

Global Customers Are Taking a Closer Look at Focused Photonics Inc.

Published

HANGZHOU, China, April 24, 2026 /PRNewswire/ — For scientific instrument companies competing globally, differentiation increasingly depends on more than product specifications alone. Customers are looking beyond performance claims to assess whether a company can consistently translate technology into manufacturable products, proven applications, reliable delivery and long-term service support.

That shift was evident during Focused Photonics Inc.’s (FPI) Global Customer Experience Day 2026 in Hangzhou, where customers and partners from dozens of countries visited the company’s Qingshanhu Innovation Base, headquarters and live application sites. For many attendees, the event offered a closer look at how a China-headquartered scientific instrument company is building capabilities across R&D, manufacturing, systems integration and lifecycle support.

At Qingshanhu Innovation Base, visitors saw key stages of FPI’s operations firsthand, including engineering, precision manufacturing, system integration, testing and service readiness. For many international customers, these visits are less about viewing a production line and more about assessing execution: whether a supplier has the engineering discipline, manufacturing depth and support infrastructure required to deliver consistently in real operating environments.

This is becoming increasingly important across the industry. As customer expectations evolve, competition is moving beyond stand-alone instrument performance toward integrated solutions, automation, data integrity, compliance and lifecycle value. In industrial and environmental applications in particular, uptime, stability and workflow fit often matter as much as analytical capability.

At its global customer conference, FPI outlined how it is responding to that transition, highlighting continued investment across environmental monitoring, industrial process analysis, laboratory analysis and life science applications. The company is also expanding the role of digitalization, automation and AI to improve application readiness and solution delivery.

Application-focused exchanges during the event reinforced the same point. In discussions on environmental, industrial and laboratory scenarios, customers focused not only on performance metrics, but also on regulatory fit, workflow integration, long-term operation under complex conditions, and the ability of solutions to function reliably once deployed. These are increasingly central criteria in global purchasing decisions.

The clearest proof came from real-world settings. At the Hangzhou Ecological Environment Monitoring Center, visitors saw FPI’s automated water quality laboratory in operation, where sample handling, workflow continuity and data generation are integrated into day-to-day use. For customers, this offered a more concrete view of how a solution performs not just in demonstration, but in routine operation.

Taken together, the event underscored a broader industry reality: global competition in scientific instruments is increasingly defined not only by what a product can do, but by whether a company can manufacture it at scale, deploy it effectively, support it locally and sustain performance over time. That broader operational capability is becoming a decisive part of how international customers evaluate suppliers.
