Double Esterlon™ - 1

DOUBLE ESTERLON Double Esterlon is a double braided rope constructed of high tenacity 1W81 polyester fiber, which has a unique cordage finish. This yarn with an average strength of 9.2 grams per denier, along with Yale's careful attention to converting machinery setup, and the yarns extraordinary lubricity, yields the highest strength double braid polyester available. Double Esterlon has low stretch, high strength, excellent wear life, dielectric strength and is completely spliceable delivering the cataloged strengths when spliced properly. It is identified by two green strands braided into the cover structure, and is available with optional Maxijacket urethane coating to further enhance the ropes wear resistance. Average Spliced Break Strength* Minimum Spliced Break Strength* * Knots and abrupt bends significantly reduce the strength of all ropes and lowers maximum working load. ** Working load is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of line's rated working load constitutes hazardous shock load and would void normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and safe use of rope. Double Esterlon is made to Yale Cordage Specification #YCI-DE-022. Energy Absorption The colored area under the curve represents the rope's ability to do "work" and is expressed in foot-pounds per pound of rope in tension. ■ Green working 291 ft. lbs./lb. Dielectric Strength: The maximum allowable leakage for clean, dry Double Esterlon is 100 Micro Amperes when tested at 90KV per ASTM 1701-05 "Routine Production Test". Absorbed and entrained moisture or impurities will increase ropes conductivity dramatically.
