Semi-conductive cushion tape for cables is a specialized type of tape used in high-voltage power cable systems. It is designed to provide electrical insulation and mechanical support to the cable, while also maintaining a semi-conductive surface to ensure the even distribution of electrical stresses.
The tape typically consists of a semi-conductive layer sandwiched between two layers of insulating material, such as rubber or plastic. The semi-conductive layer is typically made from carbon or metal particles, which provide the necessary conductivity.
The cushioning effect of the tape helps to absorb mechanical stress and reduce the risk of damage to the cable during installation and operation. The semi-conductive surface of the tape ensures that electrical stresses are evenly distributed across the cable, reducing the risk of electrical breakdown.
Semi-conductive cushion tape is commonly used in high-voltage power cable systems, including underground and submarine power cables, as well as in overhead transmission lines. It is typically applied in multiple layers and is used in conjunction with other types of cable accessories, such as joints and terminations, to ensure the safe and reliable operation of the cable system.
