In today’s infrastructure landscape, cable durability is vital. Tratos Group, a leader in electrical and fibre optic cable technology, emphasises innovation in its R&D activities. The durability and reliability of underground cables are critical, especially in utility-scale photovoltaic plants. The article “A New Technology for Termite-Proof Underground Cables” published on IEEE Xplore, marks a revolutionary advancement in protecting vital electrical infrastructure from biological threats.
This recently published paper, with the contribution of Tratos Group Vice President, Elisabetta Bragagni Capccini, who also serves as Health & Safety Director, addresses the severe consequences of termite attacks on buried lines and presents innovative solutions that integrate advanced materials and engineering practices to extend cable life and ensure operational efficiency.
The paper discusses a persistent yet often overlooked challenge: termite damage. As the study explains termite-induced deterioration not only affects cable insulation but can also lead to significant outages in power delivery.
The article encapsulates the core issue of damage due to termites in buried lines, which are usually installed in utility-scale photovoltaic plants. The insulation damages and out-of-service due to the insulation breakdowns are identified in a real case plant in Brazil.
With a robust history of developing high-performance electrical and fibre optic cables, Tratos Group has consistently pushed the envelope of technology. The strategic acquisition of complementary businesses and continuous investment in R&D have strengthened its position as a global leader
Moreover, the company’s forward-thinking approach has enabled the conception and production of a reinforced MV cable featuring a termite/rodent-proof layer made of fibreglass. This innovative design not only addresses the immediate threat of termite damage but also sets a new benchmark in cable protection technology, thereby reducing maintenance costs and enhancing overall system reliability.
The implications of this research extend far beyond a single case study. By providing a viable solution to termite-induced failures, this technology promises to revolutionise the design and deployment of underground cables in photovoltaic plants and other critical infrastructures worldwide. The successful integration of this technology signals a broader shift towards more resilient and sustainable energy systems. Future work will likely focus on refining diagnostic tests for early failure detection and further enhancing cable materials to withstand diverse environmental challenges.
As the industry evolves, collaboration between research institutions, industry leaders, and regulatory bodies will be crucial. The integration of innovative materials and advanced testing methods could pave the way for new standards in cable manufacturing and maintenance, ensuring long-term operational reliability and safety.
Along with the innovative drive of Tratos Group, the reinforced MV cable with a termite/rodent-proof fibreglass layer stands as a testament to the power of interdisciplinary collaboration and forward-thinking management. This pioneering work promises to secure critical infrastructure and inspire further advances in cable technology.
