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.
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 climbing animals can cause faults by bridging connections on poles or conductors. To address these challenges, subtransmission structures rely on solutions such as line markers and bird flight diverters, which enhance visibility and reduce avian risks across extended distances.
Balancing wildlife safety & power stability
Wildlife protection in subtransmission systems requires targeted strategies to address the challenges posed by their expansive structures and energized components. Effective mitigation protects wildlife and maintains the reliability and safety of the electrical grid. Key approaches include:
Safe maintenance
Keep crews safe without de-energizing lines or disrupting service while working on energized equipment.
Wildlife challenges
Due to their extended spans, elevated structures, and exposed equipment, subtransmission systems face unique wildlife challenges. These factors create risks for both the grid and local wildlife, requiring proactive measures to minimize disruptions and protect the environment.
