Abstract:As an important part of high voltage alternating and direct current cable, semi-conductive shielding layer has the function of eliminating defects at the interfaces between cable insulation and conductor or metal shielding, thus making the interfacial electric field uniform. In this paper, the conductive mechanisms of semi-conductive shielding composites are discussed, as well as the positive/negative temperature coefficient (PTC/NTC) effects. In view of the research progress of the semi-conductive shielding layer, the influencing factors of surface smoothness of shielding layers was analyzed, and an accurate evaluation method of surface smoothness by using surface 3D profiler scanning based on white light interferometry was proposed. The effects of polymer matrix and conductive filler on the volume resistivity and the PTC effect of semi-conductive shielding composites were systematically reviewed. It is presented that a semi-conductive property at high temperature can be modified by using the combination of high aspect ratio filler and carbon black filler. Aiming at the high-voltage direct-current (HVDC) cable, the mechanism of the interface energy band structure of semi-conductive shielding layer on the space charge injection and accumulation is analyzed. Finally, the current limitations of domestic semi-conductive composites are analyzed, and the development directions of semi-conductive composites for thermoplastic environment-friendly HVDC cable is prospected.
