based on field conditions and as directed by the engineer. Equip each span with 2 strain insulators unless otherwise directed by the engineer. Install t he strain insulator no less than 8 feet above the ground if the span wire is broken below the insulator.
with the end of the span wire extending back parallel with the span. Do not allow the span wire to cross over or overlap itself on the pole.
and place the second clamp 1 -inch away from the first.
