Specific functions of heat shrinkable cable accessories, surge arrester manufacturers

Commonly used power cables are composed of four main structural layers: conductor, insulation, shielding, and sheath. The heat-shrinkable cable terminal and heat-shrinkable cable intermediate joint as part of the cable line in the heat-shrinkable cable accessories must be The structural layers are respectively continued, cold-shrinking the cable terminal and realizing good conductor connection, reliable insulation, good sealing and sufficient mechanical strength, ensuring the quality of the cable terminal and cable joint, and ensuring the reliability of the power supply of the entire cable distribution network.

At the cable terminal and joint, the electric field distribution is much more complicated than the cable body due to the disconnection of the cable metal sheath and shielding layer. There is axial stress in the electric field at the cable terminal. Therefore, it is necessary to use heat shrinkable cable accessories to realize the continuity of the cable Docking is a connecting device that can meet certain insulation and sealing requirements.
