wholesale price semi conductive water blocking filler rope water blocking filler rope one world 2 product

Semi-conductive water-blocking filler rope is a specialized material used in the cable industry to provide electrical conductivity and water-blocking properties. It is designed to fill the space between cables and cable components, preventing water and moisture from entering and causing damage to the cables.

Water-blocking filler rope is typically made of superabsorbent polymer (SAP) or other water-absorbing materials, which swell when exposed to water, effectively blocking its passage. The semi-conductive property is achieved by incorporating conductive particles or carbon black into the material.

Semi-conductive water-blocking filler rope is commonly used in high voltage (HV) and extra-high voltage (EHV) power cables to improve their electrical performance and reduce the risk of cable failures caused by water ingress. It is also used in communication and fiber optic cables to prevent moisture from affecting signal transmission.

Overall, the use of semi-conductive water-blocking filler rope in cables is critical for maintaining cable performance and reliability, especially in harsh environments with high moisture levels.
