Strategies for Electrocution Minimization
Creating raptor-safe configurations

• New construction
• Reframing
• Retrofitting

Raptor-safe Construction
Building structures to raptor-safe standards can
save time and money in the long run.
Lowered crossarm
10-foot crossarm
4
Reframing
Existing crossarms can be replaced to obtain 60
inches of spacing between lines...
Replacing streamline arm with 10 foot arm
5
Reframing
...or lowered to obtain 60 inches of spacing
between lines.
6
Retrofitting
Devices can be installed to either
prevent birds from perching
allow birds to safely perch
-or-
Perch guard, or triangle
Insulator cover
7
Improperly sized or placed perch guards do not
work.
8
Retrofitting
Post-mounted Poles
When bases are bonded, birds perching on
insulators can make contact with the base and the
conductors.
9
Triangular perch guards mounted to the conductor
have been successful in some areas...although
mortalities have continued to occur in others.
10
Utilizing 138kV polymer insulators has proven
successful in areas with eagles and is a better
alternative.
