How to make cable terminals and intermediate joints
2024-09-27
The joint at the two ends of the cable line is called the cable terminal head, the joint in the middle is called the intermediate joint, and the terminal head and the intermediate joint are collectively referred to as the cable head. The cable head is generally made on site after the cable is laid in place. Its main function is to keep the cable sealed, so that the line is smooth, and the insulation level at the cable joint enables it to operate safely. There are many ways to make cable heads, but most of them are heat-shrinkable and cold-shrinkable.
Compared with the heat-shrinkable cable head, the cold-shrinkable cable head is easy to make; it is less affected by human factors, and the cold-shrinkable cable accessories will maintain a synchronous breathing effect with the cable as the cable expands and shrinks, so that the cable and accessories always maintain Good combination status and other advantages, but high cost. The main advantage of the heat-shrinkable cable head compared with the cold-shrinkable cable head is only low cost, so the cold-shrinkable cable head is widely used in the field of more than 10KV.
