Beimg in Michigan... lower Michigan, I'm in a bit cooler climate but I
have a 100' (97 ft according to the book) of 45G guyed with
Phillystran. It's been up now for close to 10 years and shows no sign
of deterioration. The bottom two tier of guys are HPTG4000I while the
top tier are HPTG6700I. They have had to be retensioned once, but
mainly due to the elevated guy anchors shifting a couple of inches even
though they weigh 17,000#. Back guying the anchors was not an option,
but would likely have kept them from shifting.
If I'm not mistaken, Phillystran is Kevlar with a strong jacket to
protect it from the elements... I just looked it up and to quote the
Texas Towers catalog "Phillystran® is an electrically transparent
nonmetallic guy cable which offers complete guy line isolation,
eliminating the need for insulators. It's constructed of Kevlar® fiber,
covered with an extruded copolymer jacket which provides full UV
protection."
You do need to use "Guy Grips" with thimbles at both ends of the guys.
Also the bottom 10-15 feet of each guy should be made up of EHS of the
proper size to protect the Phillystran from Critters, Implements, fire,
and vandals.
Prepare to expand your vocabulary when you install the first couple of
"Guy Grips". Once you get the hang of it they are *relatively* easy to
install. <:-)) The cable should be under tension when you install the
grips (recommended in the guide...ask for one to make sure you get one)
. I use a double cam like device (I've forgotten the name) to grip the
cable. I measured them to length plus enough to tie one end to a guy
anchor pole and the other to my "come along" AND allowing for the 10 -
15 feet of EHS on the bottom end. IIRC You'll need to install the
thimble at this point . I used a large screw driver with a smooth,
round, shank as a winding too. Be sure to follow the directions as to
which side of the Guy Grip to start winding first. They are color coded
and one side is slightly longer than the other.
