Semi-conductive single-side water-blocking tape and semi-conductive cushion tape are two different types of tapes used in different applications.
Semi-conductive single-side water-blocking tape is typically used for cable insulation and is designed to prevent the penetration of water into the cable core. This tape has a semi-conductive layer on one side and a water-blocking layer on the other side.
On the other hand, semi-conductive cushion tape is used to provide a cushion between the cable core and the cable sheath, and also to provide semi-conductive properties to the cable. This tape has a semi-conductive layer on both sides, and is typically thicker than the water-blocking tape.
Both tapes are important components in cable manufacturing and serve different purposes in ensuring the proper functioning and longevity of the cable.
