While looking through the Glen Martin Engineering web page I came across the
fact that they sell Kevlar cable. The Phillystran name is nowhere to be
found. Kevlar is made from an aramid fiber produced by E. I. Dupont.
They sell 2100, 4000, and 6700 lb breaking strength versions that run quite
a bit higher than Phillystran (I have 1997 prices maybe its gone higher).
HP-2100 60 cents/ft
HP-4000 98 cents/ft
HP-6700 $1.36/ft
no mention of volume pricing.
Unlike Phillystran they recommend heavy duty thimbles, U-bolt cable clamps
(4 per end) and an end cap to keep the kevlar from unravelling. This is for
all sizes not just 2100.
Refer to http://www.glenmartin.com/catalog/page18.html for the full info.
No relationship with Glen martin just information I though towertalkers
would want the info.
