Processing technology of cable for high-power energy storage power station with easy heat dissipation

Abstract

The present application relates to cable processing technical field, specifically, it relates to the cable processing technology for easy heat dissipation high-power energy storage power station. It includes the following steps: the oxygen-free copper pole is made into the conductor core; the boron nitride is treated by surface amido functionalization, then the aminated boron nitride is mixed with phosphorus hetero triazine compound to form covalent hybrid; the hybrid is mixed with other raw materials to prepare the master batch, then the master batch is used as the additive to obtain the insulating layer; the surface of the insulating layer is continuously coated to complete the preparation of the cable. In the present application, the conductor interface air gap is eliminated and the electric field is homogenized by the inner shielding layer, the thermal stress is buffered by the transition layer, the hybrid axial orientation is realized under the induction of ultrasonic standing wave field, and the phosphorus hetero group is activated to form carbon by step-by-step radiation crosslinking, the insulation and flame retardant properties are simultaneously strengthened; finally, the longitudinal heat conduction is enhanced by the copper shielding layer dendritic micro channel, the heat dissipation area is expanded by the corrugated aluminum sheath, so that the interface thermal resistance of the cable is reduced and the heat dissipation performance of the cable is improved.
