A semi-conductive cushion tape and a semi-conductive water-blocking tape are two different types of tapes used in cable manufacturing.
A semi-conductive cushion tape is used to provide electrical conductivity between the cable’s conductor and its semiconducting layer. It is also used to provide cushioning and to maintain a uniform separation between the conductor and the semiconducting layer.
On the other hand, a semi-conductive water-blocking tape is used to provide water-blocking properties to the cable. It is designed to prevent the ingress of water into the cable’s core, which can cause damage and affect the cable’s performance. The semi-conductive layer provides electrical continuity between the conductor and the water-blocking layer, and the tape is typically made of non-woven materials that can absorb and retain water.
