Semi-conductive nylon tape and semi-conductive cushion tape are commonly used in the cable industry for shielding, insulation, and protection purposes. The semi-conductive property of these tapes helps in maintaining the electric field uniformity and reducing the electrical stress concentration in the cable. The nylon material provides mechanical strength and resistance to abrasion, while the cushion tape provides additional insulation and protection against moisture. These tapes are often used in high-voltage power cables and other applications where electrical insulation and shielding are critical.
