PP filler rope is a type of cable filler material made of polypropylene (PP) fibers. It is commonly used in the cable industry as a filler material to occupy the interstitial spaces between the cable cores or between the cores and the cable jacket. This helps to maintain the round shape of the cable and prevent deformation, while also reducing the cable’s weight and cost.
On the other hand, a semi-conductive filler rope is a type of filler material that is made conductive by incorporating conductive particles into the material. The semi-conductive properties of the filler rope help to maintain the electric field uniformity and reduce the concentration of the electric field stress at the interface between the conductor and the insulation. This reduces the risk of electrical breakdown and increases the lifespan of the cable.
