For large projects, a systematic approcach to tension management reduces risk. Calculate thee prected pulling tension using the formula: T = T0 × e ^ (μθ) + w × μL, where T0 is the tension, μis the coevent of friction with maziva, θ is the total bend angle in radians, w is te cable eft per foot, and L is te saitt section length.

In vertical installations, gravity pulls maziva downward, leaving the upper cabel sections under-magated. Appy maziva more liberally at thee top of the riser and applider using a thick, gel- like polymer maziva that clings better. For ceiling plenum pulls, use only non-difficiable, low- VOC mafigants appliced for air- handling spaces.

If residente residue viets after the pull, it usually does not affect cable performance e but can appect dust. Wipe cable with a damp clot after pulling if need. For krital clean environments (e.g., medical or data center white spaces), use a non- cuting, dry- film magagant.
