Preformed Line Products STF-1154P F-NECK SIDE TIE .316-.357 NEW
Tie Tube:
-For bare conductor, each tie is furnished with a Tie Tube Component. The Tie Tube is detached and applied over the bare conductor.
Identification Tape:
-Shows catalog number, nominal sizes.
Insulator Identification Mark:
-Identifies the correct insulator headstyle by colors corresponding to information on catalog pages.
Color Code and Applied Length:
-Assists in identification of conductor size, corresponding to tabular information appearing on catalog pages.
INTENDED USE:
-Side Ties manufactured of aluminum covered steel secure conductors in the side groove of interchangeable headstyle insulators. Side Ties provide an improved method of securing conductor compared to clamp-top insulators or hand ties over Armor Rods.
GROOVE-FORMED:
-The Groove-Formed design broadens conductor diameter ranges, matching DISTRIBUTION Tie. The formed loop section permits better utilization of insulator groove space so that larger conductors can be accommodated on a given insulator.
SIDE TIE WITH TUBE:
-Side Ties provide superior abrasion protection for the conductor under all types of motion, including low frequency sway oscillation, high frequency aeolian vibration and galloping.
-The tube component is recommended because it surrounds the bare conductor with a resilient cushion where the conductor would come into contact with the insulator and with the center section of the tie.
-With the Tie Tube, the Side Tie not only replaces our original armoring product, but provides superior protection by eliminating abrasion rather than sacrificing outside surfaces to abrasion. In the case of Side Ties applied over plastic jacketed conductor, Side Ties can be used without tubes because contact with the bare conductor is prevented by the jacketing itself.
-PREFORMED Plastic Side Ties are also offered as an alternate to metal ties applied over plastic jacketed conductor.
-Side Ties used without tubes can replace hand tie wire in areas where abrasion damage has not been experienced.
VIBRATION DAMPERS:
-By using Side Ties with tubes abrasion cannot reduce the fatigue life of the conductor. However, for lines where experience indicates that prolonged periods of vibration might lead to fatigue of the conductor, cause inner wire fretting, or score the insulatorÂ’s glaze, SVD's are recommended.
"Excessive" Vibration:
-Areas where abrasion damage has been known to require replacement of both hand tie wire and protective rods, or where fatigue has been found under clamps. Protective rods should be replaced when visual inspection shows approximately one-half or more of the rod diameter has been abraded.
"Severe" Vibration:
-Areas where abrasion has required replacement of hand tie wire, but damage to protective rods has not progressed to the point where replacement is necessary.
"Moderate" Vibration:
-Areas where replacement of hand tie wire has not been required, and damage is minor.
-Side Ties, with pads, provide protection on areas of "moderate" vibration.
****For areas experiencing "severe" or "excessive" vibration, supplemental use of SVD is recommended. Spiral Vibration Damper's purpose is to suppress aeolian vibration.****
MECHANICAL STRENGTH:
-The Side Tie is designed to provide longitudinal holding strength in excess of values required by the National Electric Safety Code. The holding strength is usually sufficient to contain the broken conductor to a single span, however, the Side Tie is designed to relieve the load before severe damage is done to the pole's structural components. TM-167E covers the mechanical testing of the Groove Formed Side Tie and is available upon request.
INTERCHANGEABLE HEADSTYLE INSULATOR:
-To insure proper fit and service life, it is recommended only insulators corresponding to C-Neck, FNeck, or J-Neck be used. These neck-diameter and groove-height dimensions appear on ANSI standards.
CONDUCTOR SIZE:
-The Side Tie exactly matches the DISTRIBUTION Tie's ranges, which means identical color codes on armless construction. Conductor sizes up to 1.240" O.D. can be accommodated depending on the insulator's side groove radius.
-The Side Tie is designed to permit controlled movement of unbroken conductor, reducing cantilever loading at the base of the insulator or bracket, then restore itself. We refer to this unique feature as "resilience".
RADIO INTERFERENCE:
-The RIV/TVI characteristics of Side Ties are equivalent to those of a well-made hand tie when originally installed. During service life the precontoured Side Tie assures continued fit, which would have better RIV/TVI performance than a loosened hand tie wire.
TAPPING:
-Compared to the use of protective rods, placing hot-line clamps directly over the applied legs of Side Ties cannot be recommended. Tapping over protective rods will remain permissible, however, there are now stirrups available that provide a superior method of making hot-line taps.
LINE ANGLES GENERAL GUIDELINES:
-On horizontallymounted insulators, Side Ties can normally accommodate line angles up to 10°. On vertically-mounted insulators, line angles up to 40° can normally be achieved. When insulators are mounted at various degrees of cant between the horizontal and the vertical, line angles between 0° and 40° may be accommodated depending upon the actual cant of the insulator.
