Description

[0002] With the increasing dependence of society on electricity and the need for beautification of urban construction, the cable rate in urban areas has increased year by year. As the difficulty of cable operation gradually increases, the 10kV medium-voltage distribution network is the most common and widely used distribution network system. Due to the limitations of high-voltage cable manufacturing technology, the maximum length of jointless manufacturing is 10km. It is necessary to process the joints of a single cable and splice multiple cables together to achieve ultra-long-distance transmission. At the cable joint, due to the presence of two different insulating materials, the cable body insulation and the additional insulation, their electric field distribution is different from that of the cable body, which causes a certain potential difference between two adjacent points on the same layer of insulation, namely the axial field strength, or axial stress. The insulation close to the conductor connection end is cut into a conical surface, namely the reaction force cone, and then wrapped with additional insulation. Stress cone surfaces are formed at both ends of the additional insulation, which changes the potential distribution on the insulation surface, plays a role in uniform electric field, and ensures the safety of the joint.
