Water blocking in MV XLPE cables is a crucial requirement for ensuring their reliability and durability. Water blocking technology prevents the penetration of water into the cable, which can cause damage and compromise its electrical performance. Semi-conductive water-blocking filler rope is a type of material used to achieve this water blocking in MV XLPE cables.
Semi-conductive water-blocking filler rope is made of a combination of materials, including conductive particles and a hydrophobic compound. The conductive particles enable the filler rope to create an electric field within the cable that attracts any water present towards the filler rope. The hydrophobic compound, on the other hand, repels the water and prevents it from penetrating further into the cable.
The semi-conductive nature of the filler rope helps to reduce the risk of electrical discharges and ensures the cable’s electrical performance remains optimal. It also helps to maintain the cable’s structural integrity by preventing the formation of voids or air pockets that can weaken the cable over time.
In the wholesale market, semi-conductive water-blocking filler rope is available for purchase in bulk quantities. This makes it an ideal option for cable manufacturers or suppliers who need to ensure a steady supply of high-quality water-blocking materials for their products.
Overall, the use of semi-conductive water-blocking filler rope in MV XLPE cables is a reliable and effective way to achieve water blocking. Its ability to attract and repel water, while also maintaining the cable’s electrical performance and structural integrity, makes it an essential component of many MV XLPE cables in various industries.
