A single energized phase conductor typically sits on a pole-top insulator. <br /> Distribution three-phase tangent structures, without pole-top grounds or pole-top mounted <br /> equipment, generally provide adequate separation for all but the largest raptors since 44 inches of <br /> phase separation is provided. There is also a 20-degree angle between the outer and center phase <br /> wires. This separation is appropriate in areas where large raptors are less likely to occur. In areas <br /> where eagles use these poles as preferred perches, additional protection to minimize the <br /> electrocution risk would be required. A couple of different raptor protection device alternatives <br /> and their locations are shown above in Figure 4. <br /> Figures 42 Revision Date: 11/18/19 <br /> Revision No.: MR-211 <br />
