So-called "enhanced THHN" cables have slippery jackets that purportedly require no lubricant for pulling. If William Shakespeare were a cable installation engineer pondering the advent of enhanced THHN cables, he might pen the following prose in his specifications: "To lube or not to lube? That isn't even a question!" Alas, but Willy is no longer around to help us flesh out the full tale of whether 'tis nobler to supplement enhanced THHN cables with pulling lubricants. We had to do it ourselves. Enhanced THHN may be slipperier, but the slipperiness varies depending on conduit type. And, regardless, the relevant question is: is it slippery enough? We don't wish to create a tempest in a teapot, but even the average merchant of Venice understands that lower friction is better. Our Enhanced THHN Position Paper presents data proving that high-performance Polywater Lubricants lower the coefficient of friction on enhanced THHN cables in all circumstances. They are the cheapest insurance installers can buy to prevent expensive cable damage or installation delays. Verily, the literature explains--with photographic evidence--that contractors sometimes learn the hard way that enhanced THHN's lower COF is insufficient, and that in all cases Polywater can reduce the friction further. Would a cable by any other name pull as easily? Using Polywater, the answer is yes--even more easily. The literature's message is that pulling without lubricant can be risky, even with no-lube cables. Aye, from even the smallest hamlet we hear the plea when pulls go awry: "A lube! A lube! My kingdom for a lube!" Heed the data, gaze upon the images, and recall that discretion is the better part of valor. 'Tis best to avoid the foreman's cry of woe, "O Polywater, Polywater! Wherefore art thou, Polywater?" |
