Chattanooga, Tenn. – an electrical and telephone equipment manufacturer – is using stringing lines
with Morristown, N.J.-based Honeywell International Inc.’s Spectra® fiber to pull electrical wires
through transmission towers to lower voltage areas.
The low elastic stretch lines – manufactured by high-tech rope maker Yale Cordage, Saco,
Maine – are an alternative to traditional polyester lines, which often sag because they are heavy,
and require the use of additional machinery or wire rope to complete installation.
“Our pulling machines loaded with Spectra fiber-based ropes can carry longer lengths and
work greater spans since they have a lower elongation than traditional polyester-based lines,” said
John Whitt, senior vice president, Sherman & Reilly. “In the field, these properties translate
into linemen doing their work faster and safer.”
