The specific functions of heat shrinkable cable accessories, lightning arrester manufacturers
Commonly used power cables are composed of four main structural layers: conductors, insulation, shielding and sheath layers. The heat shrink cable terminals and heat shrink cable intermediate joints in the heat shrink cable accessories, which are components of the cable line, must continue the four structural layers of the cable respectively. The cold shrink cable terminal must also achieve good conductor connection, reliable insulation, good sealing and sufficient mechanical strength to ensure the quality of the cable terminal and cable joint to ensure the power supply reliability of the entire cable distribution network.
At cable terminals and joints, due to the disconnection of the cable metal sheath and shielding layer, the electric field distribution is much more complex than the cable body. There is axial stress in the electric field at the cable terminal. Therefore, heat shrinkable cable accessories need to be used to achieve cable continuity and connection, that is, a connection device that can meet certain insulation and sealing requirements.
