PHILLYSTRAN®HIGH PERFORMANCE TOWER GUY, HPTG-I ARAMID
The excellent dielectric properties of aramid fiber plus its strength-to-weight ratio five times greater than steel plus its low-stretch, low-creep characteristics add up to an ideal material for broadcast tower guys. Today's Phillystran tower guying systems based on aramid fiber are the result of long years of experience. Starting in 1973, Phillystran's tower installations include megawatt arrays as well as towers up to 1300 feet high. Phillystran HPTG-I systems eliminate problems associated with EHS steel cable such as:
  • Electromagnetic interference (EMI)
  • Radio frequency interference (RFI)
  • Signal suppression
  • Directional irregularities
  • Zapping and white-noise arcing associated with ceramic insulators interference with TV reception near broadcast sites

CAUTION:

Break Strength:The breaking strength of a rope is the load at which a new rope will break when tested under laboratory conditions. Break strength should not be mistaken for safe working load.

Safe Working Load: Because of the wide range of rope use, rope condition and the degree of risk of life or property, it is not possible to make a blanket recommendation for safe working load. It is ultimately dependent on the rope user to determine what percentage of break strength is their own safe working load.

Wear: Ropes wear out with use; the more severe the usage, the greater the wear. It is often not possible to detect wear on a rope by visible signs alone. Therefore, it is recommended that the rope user determine a retirement criteria for ropes in their application. For assistance in developing safe working load and retirement criteria for each application please call or write Phillystran, Inc.
