Every year, the manufacturing amount of high-voltage cables in China is continuously increased at a high proportion, and the total yield exceeds the United states at present, so that the high-voltage cables become the first major wire and cable producing country in the world.

Most of the common high-voltage cables are insulated by crosslinked polyethylene, so that crosslinked polyethylene insulated cables, called crosslinked cables for short, are formed, and are suitable for power frequency alternating-current power lines of 500KV and below.

In the production process of the crosslinked cable, a crosslinked cable production line is mostly used. In production, since the length of each coil of conductor is limited, in order to ensure continuous production of the crosslinked cable, the ends of the conductors need to be spliced. Currently, a production worker generally uses a sleeve 100 (as shown in fig. 1) to connect the ends of two conductors, and in more detail, first, two front and rear conductor ends to be connected are respectively inserted into cavities at two ends of the sleeve 100, and then, the sleeve 100 is crimped by using hydraulic pliers, so as to finally realize the butt joint of the two conductors. The sleeve here functions as a joint. Since it takes time to crimp the ends of two conductors by using the sleeve, in order to ensure the continuous operation of the production line, when the last coil of conductor has a length of 20 m, the end of the conductor needs to be pulled out from the coil in advance, and then butt-jointed with the end of the next conductor, and during the butt-jointing process, the pulled conductor will slide in contact with the ground, so that the pollution of the conductor is caused, and the quality of the cross-linking process and the safety during the subsequent use are seriously affected.
