Cause of cable joint manufacturing
Before the high-voltage cable joints, such as wrapping, mold casting, molding, and other types, it is necessary to make a large amount of work in the field. And because of the limitation of the field conditions and the reasons for the production process, there will inevitably be air gaps and impurities between the insulating layers, so it is easy to have problems. The types commonly used in China are assembled and prefabricated.

Cable connector is divided into cable terminal joint and cable intermediate joint. No matter what joint form, the cable joint failure usually occurs at the cable insulation shield fracture, because it is the part of the electrical stress concentration. Because of the cause of the failure of the cable joint, the cause of the cable joint failure is the defect of the stress cone body, the problem of insulation filler, the seal. Ring oil leakage and other reasons.
