Subtransmission structures require their own unique mitigation solutions, designed for high voltage and to be easily installed

Subtransmission structures are a crucial link between the high-voltage transmission grid and the local electrical distribution system. These structures play a vital role in ensuring power flows efficiently from the transmission network to end users. However, they are also vulnerable to wildlife-related outages, which have historically been difficult to mitigate. Power Line Sentry’s subtransmission product category offers innovative solutions designed to address the unique challenges posed by wildlife interactions at these critical junctions.

Building resilient energy infrastructure

The potential for wildlife to cause outages at subtransmission structures is significant due to their high-voltage equipment and elevated access points. Protecting subtransmission assets is essential for preventing disruptions to power delivery and reducing the likelihood of expensive repairs. By implementing proactive wildlife protection, utilities can improve their distribution management systems, minimize environmental impact, and ensure reliable power for the communities they serve.

Wildlife risks

Subtransmission systems cover vast geographic areas with exposed lines, making them particularly vulnerable to wildlife interactions. Birds frequently collide with power lines, especially in low-visibility conditions, while nesting birds can cause faults by bridging connections. To address these challenges, subtransmission structures rely on solutions such hawk eye bird flight diverter line markers, which enhance visibility and reduce avian risks across extended distances, as well as raptor guard nesting diverters and raptor guard perching diverters.
