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.
