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.

* 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.

■ Red ultimate 7,711 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.
