Uniline is a parallel-core cable of PET (polyester) filament. The Uniline core is bonded together with a rubber-based adhesive, wrapped with red rubber tape, over-braided with a tough polyester sleeve and entirely saturated with another rubber solution.
The cable is then cured in an oven, causing the rubber to advance to a solid layer with very tough mechanical properties. The red rubber layer not only acts as a moisture barrier, but is also a wear indicator. This cable carries a 4:1 workload rating for overhead work and a 3:1 rating for underground work.
Uniline is the toughest conventional polyester stringing line you can buy and minimizes the elasticity and stretchiness seen in polyester ropes. Ropes removed from machines having seen 20 years of service regularly test at 75% of the original strength and above. Uniline can be spliced both in eyes and as a running splice, delivering the full strength as cataloged. Alternately, Uniline can be terminated and/or end-for-end joined together with our TechEye3 and TechJoin3 products.
Uniline Lifeline is a specialized construction utilizing a solution-dyed polyester sleeve and no additional external coating. Uniline Lifeline is only available in 1/2” and 5/8” diameters in the following color options - solid orange, solid black and solid gray.
|Diameter (Inches)||Average Spliced Break Strength *(Lbs)||Minimum Spliced Break Strength *(Lbs)||Maximum Working Load 4:1 **(Lbs)||Weight (Lbs/100f)|
* Knots and abrupt bends significantly reduce the strength of all ropes and lower the 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 the rope’s rated working load constitute hazardous shock load and would void the normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and the safe use of rope.
Green working 262 ft. lbs./lb.
Red ultimate 5,230 ft. lbs./lb.
Specific Gravity: 1.38
Dielectric Strength: The maximum allowable leakage for clean, dry Uniline is 50 micro- amperes when tested at 100kV per Yale Method 712-1701 Rev 1 "Routine Production Test". Absorbed and entrained moisture or impurities will increase rope’s conductivity dramatically.
Approved Splice Technique: #10018010, #10018051.
