[TowerTalk] Phillystran suppliers

[Grant Saviers]

Not much hurts the Kevlar core other than UV, crushing, and very sharp 
bends.

There is "original" Phillystran that can't be terminated with grips as 
the cover does not adhere to the core.  I used 25K# reclaimed "original" 
for my tower using potted terminations, see NCJ 11/2014.

Guy grips IMO are a bad termination for any but the smallest Philly.

You could also get a pull test done on a sample guy. Probably a good 
idea for "a couple of 160ft towers."  Many commercial rigging suppliers 
have the pull test beds to way beyond 6700#.

The pile was all 6700 pound Phillystran, just as they were installed, with thimbles and short Rohn EHS guys attached to each end.  I bought the whole pile for a good price.  I am thinking of using them to put up a couple of 160 foot towers.    On Friday, September 10, 2021, 04:59:49 AM CDT, Mpridesti via TowerTalk <towertalk at contesting.com> wrote:

Amazingly strong and D4C with all their trade winds, holds towers without issue. Recall it was nearly a 1/2 inch OD.
