A graphene-enhanced composite resin is currently undergoing field trials on railway networks across South America, offering a promising solution to a persistent issue that has disrupted service for thousands of passengers.

In recent months, extensive copper cable theft has caused severe interruptions to rail services, posing significant risks to the safety and reliability of electrical infrastructure throughout the region. To address this growing concern, Graphenano Brasil, in partnership with Graphenano Composites, has developed an innovative protective system that is now being successfully tested in several South American countries, including Brazil.

"Graphene is emerging as a crucial ally in the fight against vandalism and transport disruptions."

The system employs a high-strength resin infused with graphene to encase copper cables, rendering unauthorized removal nearly impossible without the use of industrial-grade equipment. This dramatically lowers the appeal of such cables to potential thieves. In addition to its exceptional mechanical durability, the graphene-enhanced resin offers superior thermal conductivity, which helps dissipate heat, prevents cable overheating, and ensures consistent electrical performance along with electromagnetic shielding.

“Cable theft results in millions of dollars in damages and compromises public safety. Our technology is designed to safeguard critical infrastructure by leveraging advanced materials such as graphene,” said a spokesperson for Graphenano Composites.

The positive outcomes observed in the initial deployment have attracted interest from railway operators and electric utilities in other regions. Beyond physical protection, the solution offers substantial reductions in maintenance and repair costs, while also enhancing service reliability.

With this pioneering application, Graphenano Composites reinforces its position as a global leader in the development of advanced materials for the protection of essential infrastructure.
