For instances where pulling cables through electrical conduits or innerducts is required, many opt to utilize a pull tape over a pulling rope. But why is this?
We had previously discussed how to use these tapes effectively. Now, however, it is important we take a comparative approach to see how the benefits of this tape outweigh that of a pulling rope.
Preventing Burn Through
When a polypropylene rope shreds through the walls of PVC conduits and/or ducts, this is known as conduit burn through. Pulling ropes, when pulled, are known to be extremely abrasive against the conduit walls, ultimately resulting in conduit damage and the destruction of the cable insulation.
On the other hand, a pull tape has been designed to offset the heat and friction produced, especially via the pre-lubrication they have undergone. These qualities allow them to prevent conduit breakage and cuts when pulling cables.
Maintain Cable Functionality
The burn through produced by pulling ropes discussed above leads into another detrimental effect – fibre optic damage. As a by-product of the conduit damage that occurs on the cable’s outer sleeve, unequal loading and stress is placed on the fragile optical fibres, resulting in uncharacteristic deformations to the cable that can result in failure.
Unlike what you will encounter for pulling rope, pull tapes are frequently seen to display meter graduations along the tape – allowing the installer to determine the precise location of the cable during installation. This small, yet effective, solution removes the need for measuring tapes – saving costs, and diminishing downtime.
Equipment You Can Rely On
We’ve been supplying clients, across a multitude of industries, with some of the strongest pull tape available for nearly 60 years.
