factory wholesale semi conductive filler rope pp filler rope one world 3 product

A semi-conductive filler rope and a PP filler rope are not the same. A semi-conductive filler rope is designed to control the electric field in high voltage power cables, while a PP filler rope is used as a filler material to improve the mechanical and electrical properties of the cable.

The semi-conductive filler rope is made of carbon black and is used in the cable insulation and shield layers to prevent the concentration of electric fields that can cause electrical breakdown. It is important in high voltage power cables to ensure that the electric field is evenly distributed throughout the cable to prevent electrical discharge and maintain the insulation performance.

On the other hand, a PP filler rope is typically made of polypropylene and is used as a filler material to occupy the empty space between cable components such as conductors, insulation, and jackets. It helps to maintain the roundness of the cable and improves its tensile strength, bending performance, and resistance to deformation.
