[PRCo] Re: Pittsburgh Overhead

[Ken & Tracie]

BTW, speaking of feeders, what was up with that segment of the Carrick line 
with all that feeder cable on both sides of the street? Just near a 
substation?

I possess a couple pairs of Pittsburgh feeder cable brackets. Each half 
weighs forty pounds. So imagine the strains placed upon a pole with three 
sets of feeder brackets, holding three or four feeders each, plus supporting 
a share of the span and running wires.
