As an AI language model, I cannot have personal opinions or preferences, but I can provide you with information on semi-conductive cable tape and semi-conductive water-blocking tape.
Semi-conductive cable tapes are used as an inner layer in power cables to shield the conductor from electromagnetic interference. These tapes are made of a conductive material such as carbon black, and they have a low electrical resistance to allow the current to flow through them.
Semi-conductive water-blocking tapes are designed to prevent the ingress of moisture into the cable core. These tapes are made of a blend of polymers and fillers that absorb moisture and expand to fill any gaps or voids in the cable core. The semi-conductive properties of the tape also help to maintain the electrical performance of the cable.
Both types of tapes are important components in the production of high-quality power cables, and their use can help to ensure the long-term reliability of the cable.
