Explain in detail the reasons for the manufacture of cable connectors. Usually, the problems that are prone to occur in the cable production process are insulation eccentricity, uneven thickness of the insulation shielding layer, impurities in the insulating layer, protrusions in the inner shielding layer and outer shielding layer, The degree of cross-linking is uneven. The reasons for the manufacture of cable connectors are explained in detail. Usually, the problems that are easy to occur in the cable production process are insulation eccentricity, uneven thickness of the insulation shielding layer, impurities in the insulating layer, inner shielding layer and Protrusions in the outer shield, uneven degree of cross-linking, moisture of the cable, poor sealing of the metal sheath of the cable, etc. Seriously, failures can occur during completion testing or shortly after operation. And most of them exist in the form of defects in the cable system, which constitute a serious hidden danger for operators.

Long-term safe operation of cables, manufacturing reasons for cable connectors High-voltage cable connectors used in previous packaging types, die-casting types, molded types, etc. require a lot of work, and due to the limitations of field conditions. Due to the manufacturing process, there are inevitably air gaps and impurities between the layers of the insulating tape, which are prone to problems. The types commonly used in China today are assembled and prefabricated, and cable connectors are divided into cable terminal connectors and cable intermediate connectors.

Regardless of the type of connector, cable connector failures usually occur where the cable insulation shield breaks. Because electrical stress is concentrated here and the cable is caused by manufacturing. The reason for the failure of the joint is the manufacturing defect of the stress cone, the problem of the insulating packing and the oil leakage of the sealing ring. layer protectors) and cable cross junction boxes.
