FIGURES <br />Figures 44 Revision Date: 7/21/20 <br /> Revision No.: MR-235 <br /> <br />Figure 4.18-5 Typical Distribution Three-Phase Pole Configuration. <br /> <br /> <br /> <br />Typical distribution three-phase pole configuration. <br /> <br />Three-phase power lines are usually constructed with an 8-foot crossarm supporting two <br />conductors. 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 /> <br />Location of implementation for: <br />PERCH GUARDS AND BIRD <br />SPIKES <br />Location of implementation for: <br />POLE-TOP GROUND MOLDING
