Semi-conductive cushion tape is typically made from semi-conductive materials and is used to provide cushioning and electrical conductivity in high-voltage cables. On the other hand, semi-conductive nylon tape is made from nylon material and is used as a semi-conductive layer in power cables to reduce the electrical stress at the interface between the conductor and insulation. Both types of tape are important components in high-voltage power cables to ensure proper electrical performance and reliability.
