Overview

Product Description

Preformed Line Products TTC-1100SC C-NECK PLASTIC LINE TIE SEMI-COND NEW INTENDED USE: -Plastic Line Ties and Plastic Side Ties are intended for use with plastic jacketed conductors and tie top ANSI C29 compliant insulators only. They are suitable for use with any plastic covered conductor such as Tree Wire or Spacer Cable. MATERIAL: -Plastic Ties are offered in two versions: Standard "PVC" and "Semi-Con" for higher voltage applications. PVC Plastic Ties are made from grey polyvinyl chloride. This material was selected for "standard" applications because of its UV resistance, tensile strength, impact strength, flexural strength, low moisture absorption and self-extinguishing properties. -Semi-Con Plastic Ties are made from a base of clear PVC (with similar mechanical properties of the PVC Plastic Ties) with a proprietary black co-extruded outer covering selected for its superior electrical tracking resistance properties. Use of this co-extruded material allows application on higher voltages and/or more stressful electrical environments than with the standard PVC Plastic Ties. VOLTAGE APPLICATIONS: -Electrical performance of any tie for covered conductors made from plastic materials (or metal) is dependent upon a number of factors, such as the line voltage, insulator style, the BIL of the line/pole, atmospheric contamination levels, type and condition of the covered conductor, etc. -The design of the insulator being used may particularly affect the electric stress environment of an installation. For example field experience suggests multi skirt porcelain insulators may provide a less stressful electrical environment than similarly rated voltage single skirt porcelain insulators, and thus offer a greater electrical "safety margin". Multi skirt polymer insulators may also provide a less electrically stressful environment due to larger leakage distances vs. porcelain insulators, and the similar dielectric characteristics of the materials used to make polymer insulators, the plastic conductor jacket, and a Plastic Tie. -Because of the complex, interwoven nature of these factors, it is difficult to make absolute voltage application recommendations for Plastic Ties on covered conductors. However as a general policy, Preformed Line Products suggests the following operating line voltage applications may be suitable: -"Standard" PVC Plastic Ties: 13kV or below. -"Semi-Con" Plastic Ties: Up to 30-35kV. ****Caution: Because of the line construction and environmental factors noted above, under certain conditions Plastic Ties (particularly the "standard" PVC Ties) may be subjected to burning or tracking, so it is important the product be evaluated by the intended user and Preformed Line Products to determine if it is suitable for use in a particular installation.**** MECHANICAL: -Testing has shown Plastic Line Ties and Plastic Side Ties will develop unbalanced and lift-off loads equivalent to, or in excess of, a hand tie over jacketed conductor. INSULATORS: -To insure proper fit and performance, it is recommended that only ANSI C29.5 or C29.7 compliant insulators having nominal neck diameters corresponding to 2-1/4" C-Neck or 2-7/8" F-Neck be used. Plastic Ties are suitable for use with either ANSI Compliant Polymer or porcelain insulators. COLD WEATHER INSTALLATION/REMOVAL: -Caution should be exercised when installing or removing any Plastic Tie in very cold weather, as the plastic material may become brittle and break at very low temperatures. It is suggested Plastic Ties be kept in a warm environment before installing at outside temperatures below approximately 25° F, although laboratory installation tests indicate they may remain supple at temperatures as low as -20°F.
